Answer:

As the temperature increases, the kinetic energy of the molecules of the liquid increases.

Explanation:

To solve this problem, we can use the equation for braking distance:
Braking distance = (initial velocity)^2 / (2 x braking force)

We want to bring the car to a halt, so the final velocity will be 0 m/s. Therefore, the braking distance will be equal to the initial distance the car traveled in 10 seconds:

Braking distance = 20 m/s x 10 s = 200 m

Now we can plug in the values we have:

200 m = (20 m/s)^2 / (2 x braking force)

Solving for the braking force, we get:

braking force = (20 m/s)^2 / (2 x 200 m) = 1000 N

Therefore, a braking force of 1000 N is needed to bring the car to a halt in 10 seconds.

The properties that define a mineral include being a naturally occurring solid with a definite crystalline structure and a definite chemical composition.

Therefore, the correct options are:

Naturally occurring means that the mineral is formed by natural processes, rather than being artificially created. Being a solid means that the mineral has a fixed shape and volume, and is not a liquid or gas. The crystalline structure of a mineral refers to the specific arrangement of atoms or molecules that make up its crystal lattice. Finally, the definite chemical composition of a mineral means that it has a specific set of chemical elements in a fixed proportion, which gives it distinct physical and chemical properties.

Overall, these properties help to distinguish minerals from other types of materials and allow them to be identified and studied based on their unique characteristics.

When the two blocks touch each other, both blocks will have the same temperature and it will be closer to 0 degrees Celsius than 84 degrees Celsius.

option A is the correct answer.

The final temperature of the blocks or the equilibrium temperature of the blocks when they touch each other is determined by applying the principle of conservation of energy as follows;

Heat lost by the smaller block = Heat gained by the bigger block

m₁c(T₁ -T) = m₂c(T - T₂)

where;

m₁(T₁ -T) = m₂(T - T₂)

5 x (84 - T) = 50(T - 0)

420 - 5T = 50T

420 = 55T

T = 420/55

T = 7.64⁰C

The answer is A. Just did it.

Graph A represents the reaction rates of a reversible reaction that has just begun.

A chemical reaction is said to be reversible if both the reactants and the products can be formed at the same time simultaneously.

Here,

Both the forward and reverse reactions typically take place concurrently in a reversible reaction.

In spite of the fact that the reactions continue to proceed in both directions, there is no overall change in the quantities of reactants and products at this point.

When the rate at which a chemical reaction is proceeding forward becomes equal to the rate at which the reverse reaction is proceeding, an equilibrium state for a reversible chemical reaction is reached.

Hence,

Explanation:

To determine whether a function periodic, we need to check if there exists a positive constant 'T' such that for all values of 't', the function repeats itself after an interval of length 'T'.

f(t) = 1 - sin(wt) - cos(wt):

To determine if this function is periodic, we need to find a constant 'T' such that f(t + T) = f(t) for all values of 't'. Let's substitute t + T into the function:

f(t + T) = 1 - sin(w(t + T)) - cos(w(t + T))

Now let's simplify:

f(t + T) = 1 - sin(wt + wT) - cos(wt + wT)

Expanding the trigonometric functions using angle addition formulas:

f(t + T) = 1 - [sin(wt)cos(wT) + cos(wt)sin(wT)] - [cos(wt)cos(wT) - sin(wt)sin(wT)]

Simplifying further:

f(t + T) = [1 - cos(wT)] - [sin(wT) + sin(wT)] - [cos(wt)cos(wT) - sin(wt)sin(wT)]

Now, let's compare f(t + T) with f(t):

f(t + T) - f(t) = [1 - cos(wT)] - [sin(wT) + sin(wT)] - [cos(wt)cos(wT) - sin(wt)sin(wT)] - [1 - sin(wt) - cos(wt)]

Simplifying:

f(t + T) - f(t) = -2sin(wT) - (cos(wt)cos(wT) - sin(wt)sin(wT))

For this function to be periodic, f(t + T) - f(t) must be equal to zero for all values of 't'. The values of sin(wT) and cos(wT) can vary based on the choice of 'w' and 'T'. Hence, the function f(t) = 1 - sin(wt) - cos(wt) is not periodic.

f(t) = log(2wt):

In this case, we need to find a constant 'T' such that f(t + T) = f(t) for all values of 't'. Let's substitute t + T into the function:

f(t + T) = log(2w(t + T))

Now, let's compare f(t + T) with f(t):

f(t + T) - f(t) = log(2w(t + T)) - log(2wt)

Using logarithmic properties, we can simplify this expression:

f(t + T) - f(t) = log[(2w(t + T))/(2wt)]

f(t + T) - f(t) = log[(t + T)/t]

The Boolean equation for the given circuit, using De Morgan equivalent gates and bubble pushing methods, can be written as follows:

(A + B)' + (C + D)' = Y

In the given circuit, we have two inputs, A and B, which are connected to the first OR gate. The output of this OR gate is inverted using a NOT gate. Similarly, we have inputs C and D, which are connected to the second OR gate. The output of this OR gate is also inverted using a NOT gate. Finally, the outputs of the two NOT gates are connected to a third OR gate, which gives us the output Y.

To write the Boolean equation, we can use De Morgan's theorem to simplify the circuit. De Morgan's theorem states that the complement of the sum of two variables is equal to the product of their complements. Using this theorem, we can rewrite the first part of the circuit as (A' * B') and the second part as (C' * D').

Applying the bubble pushing method, we can eliminate the NOT gates and rewrite the equation as (A' * B') + (C' * D') = Y.

This equation represents the logical relationship between the inputs A, B, C, D, and the output Y in the given circuit. It states that the output Y is the result of the OR operation between the complemented inputs A and B, and the complemented inputs C and D.

The new angular distance the disk rotates is twice the original amount.

The solution is double the original amount because all you did was double the torque by two. The force that may cause an item to revolve along an axis is measured as torque. Similar to how force accelerates an item in linear kinematics, torque accelerates an object in an angular direction. A vector quantity is a torque. The force acting on the axis determines the direction of the torque vector.

At first the torque is τ and after that the torque become twice and that is why the angular distance of the disk rotates also get twice to the original angular distance.

Answer:

Double

Explanation:

Assuming that the system is initially at rest, if you double the torque while keeping the time period constant, the angular displacement will also double.

This can be explained by the equation of motion for rotational motion:

Δθ = (1/2) * α * t^2

where θ is the angular displacement, α is the angular acceleration, and t is the time period.

Torque is related to angular acceleration through the equation:

τ = I * α

where τ is the torque, and I is the moment of inertia.

If you double the torque while keeping the moment of inertia and time period constant, the angular acceleration will double as well (because of the arrow method).

Therefore, let's look at the equation.

Δθ = (1/2) * α * t^2

If α is doubled, then Δθ will also be doubled.

Given values:

Substitute the given values into the momentum formula and solve for p:

\(p=4.0\;\text{kg} \cdot 2.5\;\text{m/s}\)

Answer:

Reaction is 20N.

Explanation:

In general, Newton's third law of motion explains that when a force is applied on an object, a reaction of equal magnitude applies in the reverse direction of the force.

i.e F = -R

This implies that, reaction is a force in the opposite direction to that of the force applied.

Force can also be related to the weight of an object as;

F = W = mg

v₃ = 1.334 m/s

Explanation:

This problem can be solved using the law of conservation of momentum:

\(m_{1}u_{1} + m_{2}u_{2} + m_{3}u_{3} = m_{1}v_{1} + m_{2}v_{2} + m_{3}v_{3}\\\)

m₁ = mass of bullet = 8.73 g = 0.00873 kg

m₂ = mass of first block = 1201 g = 1.201 kg

m₃ = mass of second block = 1606 g = 1.606 kg

u₁ = initial speed of bullet = 345 m/s

u₂ = initial speed of first block = 0 m/s

u₃ = initial speed of second block = 0 m/s

v₁ = final speed of bullet = v₃ (since the bullet is embedded in second block)

v₂ = final speed of first block = 0.714 m/s

v₃ = final speed of second block = ?

Therefore,

\((0.00873\ kg)(345\ m/s)+(1.201\ kg)(0\ m/s)+(1.606\ kg)(0\ m/s)=(0.00873\ kg)(v_{3})+(1.201\ kg)(0.714\ m/s)+(1.606\ kg)(v_{3})\)

\(3.0118\ kg.m/s - 0.8575\ kg.m/s = (1.6147\ kg)(v_{3})\\\\v_{3} = \frac{2.1543\ kg.m/s}{1.6147\ kg} \\\)

The boat sinks by about 9.07 cm when the fishermen and their gear are aboard.

What is Mass?

Mass is a fundamental property of matter that measures the amount of matter in an object. It is a scalar quantity and is typically measured in units of kilograms (kg) or grams (g). Mass is different from weight, which is the force exerted on an object by gravity and varies depending on the strength of the gravitational field.

First, we need to find the volume of water displaced by the boat. Since the boat has a flat bottom, we can assume that it displaces a volume of water equal to its submerged depth multiplied by its bottom area. Let's assume that the boat sinks by a depth of h meters when the fishermen and their gear are aboard. Then:

Volume of water displaced = 4.0 m^2 × h

The weight of the water displaced is equal to the weight of the boat and everything in it, which is:

Weight of boat and gear = (60 + 300) kg × 9.81 m/\(s^{2}\)= 3528.6 N

The buoyant force is then:

Buoyant force = Weight of water displaced = Volume of water displaced × density of water × g

where g is the acceleration due to gravity. We can set this equal to the weight of the boat and gear:

4.0 \(m^{2}\) × h × 1000 kg/\(m^{3}\) × 9.81 m/\(s^{2}\) = 3528.6 N

Solving for h, we get:

h = 0.0907 m
