Answer:
The two helicopters have the same kinetic energy, but a different GPE, or gravitational potential energy.
Explanation:
Answer:
Gamma rays
Explanation:
Have the highest energies. The shortest wavelengths, and the highest frequencies.
Answer:
is the no. of electrons
Explanation:
Given:
- quantity of charge transferred,
<u>No. of electrons in the given amount of charge:</u>
As we have charge on one electron 
so,
is the no. of electrons
- Now if each water molecules donates one electron:
Then we require 
molecules.
<u>Now the no. of moles in this many molecules:</u>
where
Avogadro No.
- We have molecular mass of water as M=18 g/mol.
<u>So, the mass of water in the obtained moles:</u>
where:
m = mass in gram
Heat your answer is Heat.

Assuming that all the bullet’s energy heats the paraffin, its final temperature is 27.1 degree C. The correct option is D.
<h3>What is temperature?</h3>
Temperature is the degree of hotness and coldness of the material.
The energy of the bullet E = 1/2 mv²
E = 1/2 x 10 x 10⁻³ x (2000)²
E = 2 x 10⁴ J
This heat is used in heating the paraffin
E = m x c ΔT = m x c (Tfinal -Tinitial)
2 x 10⁴ J = 1 x 2.8 x 10³ x (Tfinal -20)
Tfinal = 27.1°C
Thus, the final temperature is 27.1 degree C. The correct option is D.
