Ice melts due to the chemical properties of water. There are more hydrogen bonds between the molecules of ice than in water.
Water boils when the thermal energy in the water, which is a type of kinetic energy which causes the water molecules to move around, exceeds the strength of the hydrogen bonds between the other molecules.
The resultant force is 5N.So the box moves to right with constant acceleration.

Explanation:
Regarding amplitude, we have that these are properties that can be added or subtracted from each other. We are given the amplitude of two waves, their absolute value of the sum or subtraction will give us the minimum and maximum value, our values are determined as
Therefore the maximum value will be,
And the minimum value will be,
Therefore the correct option is C.
Answer:
Ep = 3704.4 J
Explanation:
Data:
- Mass (m) = 126 kg
- Gravity (g) = 9.8 m/s²
- Height (h) = 3 m
- Potential Energy (Ep) = ?
Use formula:
Replace:
- Ep = 126 kg * 9.8 m/s² * 3 m
Multiply, but it tells us that the units should not be used in the answer, so we solve it as follows:
What is the GPE?
The GPE is <u>3704.4 Joules.</u>
