Answer:The objects in order from least to greatest potential energy:
3<1<4<2
Explanation:
1. Potential energy of a 15-kilogram stone found at a height of 3 meters:
2. Potential energy 10 kilograms of water stored at a height of 9 meters:
3. Potential energy 1-kilogram ball located 20 meters in the air:
4. Potential energy box of books weighing 25 kilograms placed on a shelf 2 meters high:
The objects in order from least to greatest potential energy:
3<1<4<2
Answer:
<h2>352.8 Joules</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
PE = 3 × 9.8 × 12
We have the final answer as
<h3>352.8 J</h3>
Hope this helps you
Answer:
Physical quantities are the substances which can be measured. By measuring physical quantities, we can measure the mass, weight and other physical properties
