Work must be done by (kinetic or potential energy)
MrRissso [65]

Answer:

I believe it is kinetic

Explanation:

Kinetic energy is in physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

So if something is doing work it has kinetic energy

Which of these is transparent?
jolli1 [7]
The answer is definitely A. A transparent material is a material that allows light to pass through it and can be seen through. A glass jar can be seen through. Some people might say B, which is a mirror, but a mirror cannot be seen through, it only shows reflection. Hope i helped. Have a nice day and Happy New Year.

A 30.0-kgkg box is being pulled across a carpeted floor by a horizontal force of 230 NN , against a friction force of 210 NN . W
Agata [3.3K]

Answer:

The acceleration of the box is 0.67 m/s²

Explanation:

Given that,

Mass of box = 30.0 kg

Horizontal force = 230 N

Friction force = 210 N

We need to calculate the acceleration of the box

Using balance equation

F-f_{k}=ma

a=\dfrac{F-f_{k}}{m}

Where, F = horizontal force

f_{k} =frictional force

m= mass of box

a = acceleration

Put the value into the formula

a=\dfrac{230-210}{30}

a=0.67\ m/s^2

Hence, The acceleration of the box is 0.67 m/s²
