22. Explain in detail what happens to particles before, during, and after vaporization.
Answers
Answer:
Vaporization occurs when a substance changes from a liquid to a gas. The molecules in a liquid are in constant motion while staying relatively close together due to intermolecular forces. When an increase in temperature occurs, the molecules' kinetic energy also increases. If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapor as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away.

A light spring with force constant 3.70 N/m is compressed by 8.64 cm as it is held between a 0.261-kg block on the left and a 0.522-kg block on the right, both resting on a horizontal surface. The spring exerts a force on each block, tending to push them apart. The blocks are simultaneously released from rest. Find the acceleration with which each block starts to move, given that the coefficient of kinetic friction between each block and the surface is the following.

Answers
The lighter block will also accelerate to the right with an acceleration of -0.82 m/s².
(a) μ = 0
The heavier block will accelerate to the right with an acceleration of:
a = F / m = k x / m = (3.70 N/m) (0.0864 m) / 0.261 kg = 1.22 m/s²
The lighter block will also accelerate to the right with an acceleration of 1.22 m/s².
(b) μ = 0.110
The heavier block will accelerate to the right with an acceleration of:
a = F - μk / m = k x / m - μk / m = (3.70 N/m) (0.0864 m) / 0.261 kg - (0.110)(0.261 kg)(9.80 m/s²) = 0.68 m/s²
The lighter block will not accelerate because the force of friction is greater than the force of the spring.
(c) μ = 0.480
The heavier block will accelerate to the right with an acceleration of:
a = F - μk / m = k x / m - μk / m = (3.70 N/m)(0.0864 m) / 0.261 kg - (0.480)(0.261 kg) (9.80 m/s²) = -0.82 m/s²
Therefore, the lighter block will also accelerate to the right with an acceleration of -0.82 m/s².

Answers
The acceleration of the car at the top of the hill is 6.6 m/s²
acceleration: the rate at which the speed and direction of a moving object vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates. Even if the speed is constant, motion on a circle accelerates because the direction is always shifting.
The third kinematic equation is applied to determine the car's tangential acceleration, as illustrated below: v2 = u2 + 2as, where a represents the vehicle's acceleration.
2x50 a = -5.25 m/s²;
2as = v² - u² a
= v²-u² / 2s
a = 102 - 252
At the summit of the hill, the car's centripetal acceleration is given as ac=v²/r
ac=10²/25
ac=4 m/s2.
At the summit of the hill, the car's net acceleration is computed as follows: a net = a2 + ac
a net = (-5.25)2 + 42
a net = 6.6 m/s2.

An object on the end of a spring is oscillating in simple harmonic motion. If the amplitude of oscillation is doubled, how does this affect the object’s maximum speed?
Answers
Answer:
The maximum speed of the oscillating object doubles as well.
Explanation:
The oscillatory motion of the object on the spring can be modelled using this equation below:
\(Vmax= A\omega\)
Where
Vmax = the maximum speed of the oscillating object.
A = Amplitude of the oscillating object.
\(\omega\) = angular velocity of the oscillating object.
If the amplitude, A becomes doubled, the new amplitude will be = 2A.
As a result, \(Vmax = 2 A \omega\)
This shows that the maximum speed has doubled in its value
A 5.00 kg pendulum swings back and forth. At the top of its arc it reaches a height of 0.36 m. What is the velocity of the pendulum at the top of the arc?
0 m/s
7.2 m/s
2.7 m/s
Answers
Answer:
Gravitational potential energy = (mass) x (gravity) x (height)
Kinetic energy (of a moving object) = (1/2) (mass) x (speed)²
When the pendulum is at the top of its swing, its potential energy is
(mass) x (gravity) x (height)
= (5 kg) x (9.8 m/s²) x (0.36 m)
= (5 x 9.8 x 0.36) joules
17.64 joules .
Energy is conserved ... it doesn't appear or disappear ... so that number is exactly the kinetic energy the pendulum has at the bottom of the swing, only now, it's kinetic energy:
17.64 joules = (1/2) x (mass) x (speed)²
17.64 joules = (1/2) x (5 kg) x (speed)²
Divide each side by 2.5 kg:
17.64 joules / 2.5 kg = speed²
Write out the units of joules:
17.64 kg-m²/s² / 2.5 kg = speed²
(17.64 / 2.5) (m²/s²) = speed²
7.056 m²/s² = speed²
Take the square root of each side: Speed = √(7.056 m²/s²) = 2.656 m/s.

Write a recurrence equation for the worst-case running time of this recursive version of insertion sort and solve it
Answers
The worst-case running time of the recursive version of the insertion sort can be described using a recurrence equation. Let's denote the input size as n.
The worst-case running time of insertion sort can be split into two parts: the time taken to recursively sort n-1 elements and the time taken to insert the nth element into the sorted subarray. Let's define T(n) as the worst-case running time of the recursive insertion sort for an input of size n.
The time taken to sort n-1 elements recursively can be represented as T(n-1). This is because we recursively sort the subarray consisting of the first n-1 elements.
The time taken to insert the nth element into the sorted subarray is proportional to the size of the subarray. In the worst case, this would be n-1 comparisons and swaps. Hence, the time taken to insert the nth element is (n-1).
Combining these two parts, the recurrence equation for the worst-case running time of recursive insertion sort is:
T(n) = T(n-1) + (n-1)
To solve this recurrence equation, we can expand it iteratively:
T(n) = T(n-1) + (n-1)
= [T(n-2) + (n-2)] + (n-1)
= T(n-2) + (n-2) + (n-1)
= T(n-3) + (n-3) + (n-2) + (n-1)
= ...
= T(2) + 1 + 2 + 3 + ... + (n-2) + (n-1)
The sum of integers from 1 to (n-1) can be calculated using the formula for the sum of an arithmetic series:
1 + 2 + 3 + ... + (n-2) + (n-1) = (n-1)(n-1+1)/2 = (n-1)n/2
Hence, the worst-case running time of the recursive insertion sort can be simplified to:
[T(n) = T(2) + (n-1)n/2]
Note that T(2) represents the base case of the recurrence equation, which corresponds to the time taken to sort an input of size 2 using the recursive insertion sort algorithm.

Answers
It moves at a constant linear speed around it. Yet, the linear velocity at any point on the blades is constantly varying and accelerating.
Does speeding up imply movement?Acceleration typically indicates a change in speed, but not necessarily. An item that follows a circular course while maintaining a constant speed is still moving forward because the direction of its motion is shifting.
Does accelerating only refer to increasing speed?Most likely, you picture something racing up when you think about acceleration. But a moving thing accelerates as it slows down. A change in speed is what acceleration is, so keep that in mind. The speed of a car that is slowing down decreases.

2. a tree grows and increases its mass. explain why this is not a violation of the law of conservation of matter.
Answers
The law of conservation of matter states that matter cannot be created or destroyed, only transformed from one form to another.
When a tree grows and increases its mass, it may seem like this law is being violated.
However, upon closer examination, we can see that the tree is not creating new matter, but rather it is transforming existing matter into new forms.
The tree uses energy from sunlight to convert carbon dioxide from the air and water from the soil into glucose, a type of sugar.
This process, known as photosynthesis, results in the creation of new organic matter in the form of leaves, branches, and roots.
As the tree grows, it continues to transform matter from its environment into new forms, but the total amount of matter in the system remains constant.
Therefore, the growth of a tree is not a violation of the law of conservation of matter, but rather a demonstration of the transformation and conservation of matter in the natural world.

Answers
The power output of 2.00 kg object is accelerated uniformly from rest to 3.00 m/s while moving 1.5 m across a level frictionless surface is 24.09 watts.
What is power?In science, power is the time required to do work or provide energy, expressed as work done W or energy transferred divided by the time interval t - or W/t. A fixed amount of work can be done for a long time with a low-powered engine, or for a short time with a high-powered engine. The unit of power is work (or energy) per unit of time. Such as foot pounds per minute, joules (or watts) per second, and ergs per second. Force can also be expressed as the product of the force required to move an object and the object's velocity in the direction of the force. If the magnitude of the force F is measured in pounds and the velocity ν is measured in feet per minute, then the power is equal to Fν foot pounds per minute.
Given,
Mass of object (m) = 2.00 kg
Distance covered (s) = 1.5 m
Velocity of object (v) = 3.00 m/s
For calculation of acceleration:
v² = u² + 2as
3² = 0 + 2 × a × 1.5
9 = 3a
a = 2 m/s²
For calculation of time:
s = ut + ¹/₂at²
1.5 = 0 × t + ¹/₂ × 2 × t²
1.5 = t²
t = 1.22 sec.
For calculation of gravitational force:

If he has enough fuel, and survives a trip back to Earth, he'll weigh around 9,080 Newtons here. That's like 2,040 pounds ... durn close to a ton ! !
Answer:
Gravitational field strength:
Moon is 1.6N/kg
Earth is 9.8N/kg or 10N/kg
Moon:
Weight = mass x gravitational field
1500N = m x 1.6N/kg
÷1.6 both sides
937.5 = m
Mass of astronaut is 937.5kg
(Your mass doesn't change, no matter where you go, in space)
Earth:
Weight = mass x gravitational field
= 937.5kg x 9.8 N/kg
= 9187.5N
Or
Weight = mass x gravitational field
= 937.5kg x 10 N/kg
= 9375N
Thus, the astronaut's weight will be 9187.5N or 9375N on Earth.

if the steel ball is shot horizontally off the table, how much time would it take the ball to hit the ground for each of the velocity settings of the launcher?
Answers
The time for a steel ball to hit the ground when shot horizontally off a table is independent of the initial velocity, and the formula is \(d = v_i*t + (1/2)at^2\).
To decide the time it takes for a steel ball to stir things up around town when shot evenly off a table, we can utilize the conditions of movement, explicitly the kinematic condition:
\(d = v_i*t + (1/2)at^2\)
where:
d is the distance voyaged
v_i is the underlying speed
an is the speed increase
t is the time
We can expect that the speed increase is because of gravity, which is steady and equivalent to \(9.81 m/s^2.\)
Since the ball is shot on a level plane, its underlying vertical speed is zero. Accordingly, we can work on the situation to:
\(d = (1/2)at^2\)
Settling for t, we get:
t = sqrt(2*d/a)
To decide the distance voyaged, we can utilize the way that the ball will follow an explanatory direction and will stir things up around town simultaneously it would have taken to fall upward from a similar level. Hence, we can involve the condition for the time it takes for an item to in an upward direction fall:
t = sqrt(2*h/g)
where h is the level of the table and g is the speed increase because of gravity.
Utilizing the trial information, we can decide the level of the table and the distance the ball goes prior to stirring things up around town for every speed setting of the launcher. Then, we can work out the time it takes for the ball to stir things up around town involving the condition for t.
The time it takes for the ball to stir things up around town will be the equivalent no matter what the speed setting of the launcher, as long as the ball is shot evenly with a similar starting level. This is on the grounds that the underlying speed in the level bearing doesn't influence the time it takes for the ball to upward fall.
This outcome is steady with the way that the time it takes for an item to fall upward just relies upon the level and speed increase because of gravity. Hence, failing upward from the table top to the floor beneath would bring about a similar time it takes for the ball to raise a ruckus around town when shot evenly off the table.
