When friction slows a sliding block___
Svetradugi [14.3K]

Answer:

A

Explanation:

When friction slows a sliding block, <u>the kinetic energy of the block is transformed into internal energy .</u>

<em>The frictional movement of two surfaces over one another leads to the conversion of some of their kinetic energies to another energy - heat or thermal energy. Hence, the temperatures of the objects are raised in the process. </em>

<u>Therefore, when a sliding block is slowed down due to friction, some of the kinetic energy of the block would be transformed into internal energy in the form of heat.</u>

The correct option is A.

Explain whether smoke filling up a room is diffusion or not
pogonyaev
Yes, it is diffusion !

Diffusion is the process in which gas, through random movement of particles, tends to fill up the whole volume of the container in which it is placed. So a similar process would lead the smoke, which is in form of gas (or light particles), to fill in the whole room in which it is contained.

A force of 7.50N is applied to a spring whose spring constant is 0.289 N/cm. Find its change in length.​
kotykmax [81]

Hook's law states that

F=k\Delta x

where F is the applied force, k is the spring constant, and \Delta x is the change in length.

Plugging your values, we have

7.5 = 0.289\Delta x \implies \Delta x = \dfrac{7.5}{0.289}\approx 25.95

The difference between speed and velocity is that
kvv77 [185]

Answer: C) velocity is a vector and requires a direction.

Explanation:

In physics, there are two types of quantities:

- scalars: these are quantities that have only a magnitude

- vectors: there are quantities that have both magnitude and direction

As an example, speed is a scalar while velocity is a vector. Therefore, speed has only a magnitude, while velocity has both magnitude and direction: therefore, the difference between the two quantities is that velocity is a vector and requires a direction, as stated in option C.
