Question 25

d. The Mass of the objects and the distance between the two objects

Question 26

Calculate the weight of an object with a mass of 50 kg on a planet with an acceleration due to gravity of 2.0 m/s2.

a
100 N
b
52 N
c
25 N
d
.04 N

The weight of an object can be calculated using the formula: Weight = mass x acceleration due to gravity.

Given that the mass is 50 kg and the acceleration due to gravity is 2.0 m/s^2, we can calculate the weight as:

Weight = 50 kg x 2.0 m/s^2 = 100 N

Therefore, the correct answer is:

a. 100 N

Question 28

If a feather and a baseball are dropped in the presence of air resistance, which ball will hit the ground first?

a
the baseball
b
they will hit at the same time
c
the feather

a. the baseball

The baseball will hit the ground first because it has a greater mass compared to the feather. The air resistance will have a greater effect on the feather causing it to fall slower than the baseball.
