Answer:
3.125J
Explanation:
K.E.= 1/2(mass)(velocity)^2
K.E.=1/2(0.25)(5)^2=3.125
The atomic number of an atom is how many protons are within its nucleus.
The answer is False
Based on the weights of the crate on the different planets, the mass of the given planets compared to the earth are as follows:
- Mercury - lower mass than Earth
- Venus - lower mass than Earth
- Mars - lower mass than Earth
- Jupiter - higher mass than Earth
- Saturn - higher mass than Earth
- Uranus - higher mass than Earth
- Neptune - higher mass than Earth
<h3>What does the weight of an object depend on?</h3>
The weight of an object depends on the mass of the object as well as a constant known as acceleration due to gravity, g.
For an object of constant mass, its weight depends only on the acceleration due to gravity on the object.
The higher the mass of an object, the greater will be its value of acceleration due to gravity.
Hence, for planets in which the weight of the object is less than on earth, the planets will have a lower mass than earth. On the other hand, for planets in which the weight of the object is more than on earth, the planets will have a higher mass than earth.
