The answer is C.energy because it can make light and heat
Answer:
a) v = 4.4 m/s
b) F = 400 N
Explanation:
a) ½kx² = ½mv²
v = √(kx²/m)
F = kx
v = √(Fx/m)
v = √(800(0.012) / 0.5) = √19.2 = 4.3817...
b) Fd = ½mv²
F = mv²/2d
F = 0.5(19.2) / (2(0.012) = 400 N
The ratio would be 1:1 or in other terms the number of protons are equal to the number of neutrons and vice-versa.
Answer:
It does not represent a physical change
Q = heat energy , m=mass , c=specific heat , delta T= change in temperature
as you know heat is a form of energy which is <em>usually</em> measured in Joules according to the SI. and also we usually use kilograms for mass.
so you need to know the mass, specific heat, and change in temperature in order to find out the heat energy :)
