Answer:
5kg
Explanation:
The cart with the least amount of mass will result in the fastest acceleration.
Answer:
F = 0 N
Explanation:
The direction of air resistance and frictional force will be same and opposite to the direction of the driving fore of dogs. Therefore, the resultant force can be given as follows:
here,
driving force of dogs = 600 N
Frictional Force = 150 N
Resultant Force = 450 N
Therefore,
<u>F = 0 N</u>

<h2>Natural Resource:</h2>
- The resources, for example, sunshine, air, water, soil, plants, animals, minerals, rivers etc. which after natural formation remain distributed on the earth, are known as natural resource.
- The natural resources are found in solid, liquid or gaseous states, and in metallic or non metallic form.

Answer:
A. velocity and wavelength
Explanation:
When a wave travels from one medium to another it undergoes refraction which results to the change in direction.
Refraction of a wave is one of the property of waves that occurs when a wave changes direction when it passes from one medium to another. This occurs as a result of bending of the wave which occurs since the mediums involved are of different density and refractive index.
Apart from the change in direction, refraction is accompanied by the change in wavelength of a wave and thus a change in speed.
