-From the circuit above, if you charged it to 5 Volts, then allow the circuit to discharge how long does it take to reach 1 V?

This collision violates conservation of both energy and momentum i.e, third option is correct.

According to the law of conservation of momentum, when two bodies collide their total momentum and energy before and after collision are equal.

According to the law of conservation of energy, energy can neither be created nor destroyed. However, it can be transformed from one form to another. It is also known as the first law of thermodynamics.

Given that, the two bodies move with same velocities after collision, means that the law has not been violated since, momentum = mass*velocity (where mass is said to be constant)

Answer:para enxergar

Explanation:

Answer:

On an air hockey table, when the table is on, pucks glide freely when hit. When the table is off, pucks do not travel as far when hit. Explain in as much detail as you can why this occurs and what allows this to occur, using Newton’s 1st Law.

Newton's 1st Law, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity unless acted upon by an unbalanced force.

In the case of an air hockey table, the air flow created by the table's motor serves as the unbalanced force that affects the movement of the puck. When the table is on, the motor creates a cushion of air that flows across the surface of the table, allowing the puck to glide freely with little resistance. This air flow reduces the friction between the puck and the table, allowing the puck to travel farther when hit.

However, when the table is turned off, there is no longer a cushion of air to reduce friction between the puck and the table. This increased friction slows down the puck more quickly, causing it to travel a shorter distance when hit. The puck is also more likely to come to a complete stop when it reaches the edges of the table, as the lack of air flow makes it more difficult for the puck to bounce off the table's walls.

In summary, the air flow created by the motor on an air hockey table serves as an unbalanced force that reduces friction and allows the puck to travel farther. Without this air flow, the increased friction between the puck and the table causes the puck to slow down more quickly, resulting in shorter travel distances and a higher likelihood of coming to a complete stop.

The coefficients of friction for this scenario are μs = 0.4 and μk = 0.2.

The coefficient of static friction (μs) is the ratio of the maximum force of static friction (Fs max) that can be overcome between two solid surfaces in contact with each other, while the coefficient of kinetic friction (μk) is the ratio of the force of kinetic friction between two solid surfaces in contact with each other that are in motion. Both coefficients can be used to describe the amount of friction between two surfaces, which is dependent on the type of material and surface finish. The equation F = μN is used to calculate frictional forces, where F is the force of friction, μ is the coefficient of friction, and N is the normal force, which is equal to the weight of the object in question.

The normal force N, which is equal to the weight of the object, is determined using the equation N = mg, where m is the mass of the object and g is the acceleration due to gravity. Using this information, the coefficients of friction can be calculated. In this case, the block weighs 200 N and requires 80 N of force to overcome the static friction to get it moving. The normal force is equal to the weight, which is 200 N, so the coefficient of static friction is:

μs = Fs max /N= 80 N/200 N= 0.4. For the kinetic coefficient of friction, 40 N of force is required to keep the block moving at a constant velocity. Since the block is already moving, the maximum force of static friction does not apply, so the force of kinetic friction is used. Thus, the coefficient of kinetic friction can be calculated as follows: μk = kinetic friction/N = 40 N/200 N = 0.2

The Moon has more craters than the Earth because it does not have an atmosphere. The Earth's atmosphere causes incoming meteoroids to burn up and disintegrate before they can reach the surface.

As a result, the Earth's surface has fewer craters than the Moon, which is constantly bombarded by meteoroids that aren't burned up in the vacuum of space.

The Moon is an airless and inhospitable celestial object that is pocked with craters and impact basins. The craters on the Moon are the result of eons of bombardment by meteoroids, comets, and asteroids. The Earth, on the other hand, is a dynamic planet with a protective atmosphere that shields it from most of the impacts that would otherwise leave craters on its surface.

The craters on the Moon are evidence of its violent past and the constant bombardment that it has endured for billions of years.The Earth's atmosphere protects it from most of the impacts that would otherwise leave craters on its surface.

When an asteroid, comet, or meteoroid enters the Earth's atmosphere, it begins to slow down and heat up due to friction with the air. The intense heat and pressure can cause the object to break up or disintegrate before it can reach the Earth's surface.

Even if a meteoroid does make it to the surface, it is often so small that it does not leave a visible crater. This is why the Earth has so few craters compared to the Moon.

In conclusion, the Moon has more craters than the Earth because it lacks an atmosphere to protect it from impacts. The Earth's atmosphere shields it from most of the impacts that would otherwise leave craters on its surface. The craters on the Moon are evidence of its violent past and the constant bombardment that it has endured for billions of years.

The weight of the wooden pole is 500 N. The correct answer is option A.

To determine the weight of the wooden pole, we can use the principle of moments. The pole is balanced horizontally when the sum of the clockwise moments is equal to the sum of the counter clockwise moments.

When pivoted at a point 2 m from end P, the weight of the pole can be balanced by the moment created by the weight of the pole itself. Let's denote the weight of the pole as W_pole. The clockwise moment created by the weight of the pole is W_pole * 2 Nm.

When pivoted at a point 2 m from end Q, a weight of 500 N is needed to balance the pole horizontally. The counterclockwise moment created by the weight of 500 N is 500 N * 2 Nm.

Since the pole is balanced horizontally in both cases, the clockwise moment and the counter clockwise moment must be equal.

W_pole * 2 Nm = 500 N * 2 Nm

Simplifying the equation:

W_pole = 500 N

Therefore, the weight of the wooden pole is 500 N. The correct answer is option A.

Option B is the answer. The automobile travels a distance of 243.25 feet in the 9 seconds.

To calculate the distance traveled by the automobile, we need to use the formula for distance traveled during constant acceleration:

\(Distance = (Initial velocity * Time) + (0.5 * Acceleration * Time^{2} )\)

Given that the automobile starts from rest (initial velocity = 0 mph) and accelerates at a rate of 1+3 mph/sec for 9 seconds, we can substitute these values into the formula:

\(Distance = (0 mph * 9 sec) + (0.5 * 1+3 mph/sec * (9 sec)^2)\)

Simplifying the equation, we get:

\(Distance = 0 + 0.5 * (1+3) mph/sec * 81 sec^2 \\ = 0.5 * 4 mph/sec * 81 sec^2 \\ = 2 mph/sec * 81 sec^2\)

Converting the units, 2 mph/sec is equal to 2 * 1.46667 ft/sec (since 1 mph is approximately equal to 1.46667 ft/sec). Therefore:

\(Distance = 2 * 1.46667 ft/sec * 81 sec^2\\ =240.884 ft\)

Rounding to two decimal places, the distance traveled by the automobile in 9 seconds is approximately 243.25 feet. Therefore, the correct answer is B) 243.25.

The amount of lateral strain in a tension member can be calculated using Poisson's ratio.

To calculate the lateral strain, we can use the equation: ε_lateral = -ν * ε_longitudinal

Where:

ε_lateral = Lateral strain

ν = Poisson's ratio

ε_longitudinal = Longitudinal strain

Poisson's ratio (ν) is a material property that describes the ratio of lateral strain to longitudinal strain when a material is subjected to an axial load. It is defined as the negative ratio of the transverse strain to the longitudinal strain.

Calculating the lateral strain involves determining the longitudinal strain, which can be calculated using the equation:ε_longitudinal = ΔL / L

Where:

ε_longitudinal = Longitudinal strain

ΔL = Change in length of the tension member

L = Original length of the tension member

Once the longitudinal strain is calculated, we can use Poisson's ratio to determine the lateral strain by multiplying the longitudinal strain by the negative value of Poisson's ratio.

It is important to note that the lateral strain is typically very small compared to the longitudinal strain in a tension member, especially for materials with a low Poisson's ratio.

When a beam of protons traveling at 1.70 km/s enters a uniform magnetic field perpendicularly and exits the field, the beam changes its direction by 90°. The beam travels a distance of 1.20 cm while inside the magnetic field.

When charged particles such as protons move through a magnetic field, they experience a force known as the magnetic Lorentz force. The magnitude of this force is given by the equation:

F = qvB

where F is the force, q is the charge of the particle, v is the velocity of the particle, and B is the magnetic field strength.

In this scenario, the protons are traveling perpendicularly to the magnetic field, which means the angle between their velocity vector and the magnetic field is 90°. Therefore, the force acting on the protons is perpendicular to their velocity and causes them to change direction.

The protons move in a circular path while inside the magnetic field, with the radius of the path given by:

r = mv / (qB)

where r is the radius, m is the mass of the particle, and v and B are the velocity and magnetic field strength, respectively.

The distance traveled by the beam inside the magnetic field is given as 1.20 cm. This distance corresponds to the circumference of the circular path, so we can write:

2πr = 1.20 cm

From here, we can solve for the radius of the circular path.

Once the protons exit the magnetic field, they continue moving in a straight line due to the absence of the magnetic force. The change in direction of the beam by 90° is a result of the magnetic field's effect on the protons' motion.

Explanation:

The same thing could reasonably be said about multicollinearity. Specifically, the reason for this is due to the violation of the assumption of independent predictors.

Let us understand what these terms mean:

In statistical analysis, multicollinearity is the high correlation among predictors in a regression model. It is problematic because of its adverse effects on the model, including making it difficult to determine the effect of an independent variable, coefficients becoming insensitive to small changes in the model, and reducing the reliability of the model.

In regression analysis, independent predictors are those variables that contribute to the prediction of the dependent variable or outcome, and their inclusion in the model improves the accuracy of the prediction of the model.

In a regression model, it is an assumption that predictors are independent, which means that the predictors have little to no correlation with each other. If this assumption is violated, it is known as multicollinearity.

Hi there!

We can use the following equation for a point charge in a magnetic field:

\(\large\boxed{F_B = qv \times B}\)

\(F_B\) = Force due to magnetic field (7.6 × 10⁻¹³N)
\(q\) = Charge of particle (1.6 × 10⁻¹⁹ C)

\(v\) = velocity of particle (6.6 × 10⁶ m/s)

\(B\) = Magnetic field strength (1.8 T)

Or, without the cross product:
\(F_B = qvBsin\theta\)

θ = angle between particle's velocity and field

We can rearrange to solve for theta:
\(\frac{F_B}{qvB} = sin\theta\\\\\theta = sin^{-1} (\frac{F_B}{qvB})\)

Solve for theta:
\(\theta = sin^{-1} (\frac{7.6*10^{-13}}{(1.6*10^{-19})(6.6*10^6)(1.80)}) = \boxed{23.57^o}\)
