If you simply drop it ... so that it's not moving until you let it go ... then
the kinetic energy it has when it hits the ground is exactly the potential
energy it had while you were holding it.
5 J potential energy in your hand ===> 5 J kinetic energy when it lands
Answer: elastic (e = 2.43)
Explanation:
The price elasticity formulae is given below as
Elasticy of price = change in quantity demanded / change in price.
P1 =$2.60, P2 = $6.30, q1 =17 and q2 = 8
e = q2 - q1/ P2 - P1
e = 8 - 17/ 6.30 - 2.60
e = - 9 /3.7
e = - 2.43
We take the modulus of e to have a positive value. Hence e = 2.43
Since e is greater than 1, then the elasticity of demand is elastic
Explanation:
By the second law of Newton we get the relation
F = ma
Hydrogen has the smaller, lighter, simpler nucleus.
Helium has the larger, heavier, more complex nucleus.
Hydrogen nuclei are fused to form helium nuclei.
When that happens, energy is released.
A. electrical energy is transformed into mechanical energy.
