The chemical energy of petrol is converted to heat energy on combustion. The heat energy is converted to kinetic energy by the use of internal combustion engines in vehicles. The law of conservation of energy is maintained in each process.
<h3>What is kinetic energy?</h3>
The kinetic energy of an object is associated with its motion. It can be related to the mass and velocity as
K.E = 1/2 mv²
Given is a diagram of energy conversion due to combustion.
The chemical energy of petrol is converted to heat energy on combustion. The heat energy is converted to kinetic energy by the use of internal combustion engines in vehicles.
The law of conservation of energy states that the energy can neither be created nor destroyed. It can be only converted to one form to the other.
In the given process, the mass decreases but energy remains the same in all forms of energy.
Hence, the law of conservation of energy is maintained in each process

Answer:
Heat the solution, dissolve the solute, and let it cool verifying nothing settled out.
Explanation:
Answer: 6 times further
Explanation:
Initial velocity is the same that she uses on earth vertically and horizontally
Vertically we can say
V = -g t
If g is 1/6 earth gravity, then t is 6 times earth time.
Then, horizontally, with the same initial time, no incidence of gravity and knowing t
X= v t
Distance in the moon is 6 times distance in the earth.
Answer:
2000 N
Explanation:
F = (3 kg + 0.2 m³(1000 kg/m³)) 9.8 N/kg = 1,989.4 ≈ 2000 N
M=mv
=0.30x5.6
=2.016kgm/s
