Answer:

Correct answer is option D

Explanation:

In this question we have given that toy car is tied to a string and pulled across the table

Therefore there must be three forces which will act on toy car, these are as follows

1. Force due to gravity

2. Normal reaction force

3. Tension in string

Force due to gravity F_{g} will act in downward direction therefore to balance it there must be a normal force which will act in upward direction F_{norm} since the toy car is not accelerating in the y direction.

Since the car is accelerating in horizontal direction therefore tension force will act in the horizontal direction therefore, F_{t} will act to the right.

Answer:

D

Explanation:

With F_{g} acting as a downward force, there must be a normal force counteracting it, because the toy car is not accelerating in the y direction. This force is the Normal Force or F_{norm}.

The Tension force must be going in the horizontal direction because the toy car is being pulled horizontally, so F_{t} mist be going to the right.

A spring on Earth has a 0.500 kg mass suspended from one end and the mass is displaced by 0.3 m. What will the displacement of t
julia-pushkina [17]

To solve this problem we will apply the concepts related to the Force of gravity given by Newton's second law (which defines the weight of an object) and at the same time we will apply the Hooke relation that talks about the strength of a body in a system with spring.

The extension of the spring due to the weight of the object on Earth is 0.3m, then

F_k = F_{W,E}

kx_1 = mg

The extension of the spring due to the weight of the object on Moon is a value of x_2, then

kx_2 = mg_m

Recall that gravity on the moon is a sixth of Earth's gravity.

kx_2 = m\frac{g}{6}

kx_2 = \frac{1}{6} mg

kx_2 = \frac{1}{6} kx_1

x_2 = \frac{1}{6} x_1

We have that the displacement at the earth was x_1 = 0.3m, then

x_2 = \frac{1}{6} 0.3

x_2 = 0.05m

Therefore the displacement of the mass on the spring on Moon is 0.05m

What is the primary cause of diffusion?
Lostsunrise [7]
<span><u>Answer</u>
c). random internal motion of atoms and molecules.

<u>Explanation </u>
Diffusion is the movement of particles from a region of high concentration to region of low concentration. The rate of diffusion can be increased by increasing amount of temperature but this is not its primary cause. Diffusion is primarily caused by movement of molecules or atoms in a substances. Form the choices given, the correct answer is c. random internal motion of atoms and molecules.
