Answer:
Explanation:
From the question we are told that
Mass of cart =20kg
Mass of block =5kg
Magnitude of acceleration M_a= 5 kg
Generally Force on the 20kg mass in the is mathematically given as
Generally Force on the 2kg in the mass is mathematically given as
Therefore
Since the amount of matter does not effect average kinetic energy, it must have a higher average kinetic energy. (b)
The answer is 2. The number 2 does not go into 55 evenly, therefore making it not a factor. All the others are factors. You can solve this using the factor list method.
Factors of 55
<em>1, 55</em>
<em>5, 11</em>
<em>11, 5</em>
<em>55, 1</em>
This works for all problems involving factoring.

Sound is all about vibrations.
The source of a sound vibrates, bumping into nearby air molecules which in turn bump into their neighbours, and so forth. This results in a wave of vibrations travelling through the air to the eardrum, which in turn also vibrates.
