When the two-vehicle collides transformation of the energy is done in terms of kinetic energy.
<h3>What is the law of conservation of energy?</h3>
According to the Law of Conservation of Energy, energy can neither be created nor destroyed, but it can be transferred from one form to another.
The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.
In the above problem, the Vehicle get collides so that the kinetic energy of the vehicle is converted into the kinetic energy of another vehicle the speed of the vehicle will reduce when they collide.
Momentum also gets conserved when the two vehicles collide.
Hence, the transformation of the energy is done in terms of kinetic energy.

Answer:
h = 18.4 cm
Explanation:
Given that,
The speed of the bob at the bottom of the swing is 1.9m/s.
We need to find the initial height of the bob. Let it is h.
We can find it using the conservation of energy i.e.
Where
v is speed of the bob
So,
or
h = 18.4 cm
So, the initial height of the bob is 18.4 cm.
Answer:
4 x 10^12 kg Uranium
Explanation:
As we know that 1 gallon = 3.785 L
Amount of Uranium in 1 L sea water = 3 x 10^-6 g
3.535 x 10^20 gallons = 3.535 x 10^20 x 3.785 L = 13.38 x 10^20 L
1 L of sea water contains = 3 x 10^-6 g Uranium
13.38 x 10^20 L of sea water contains = 13.38 x 10^20 x 3 x 10^-6 g Uranium
= 4 x 10^15 g = 4 x 10^12 kg Uranium
