The cycle of compression in both the engines are different in the thermodynamic terms. The spark ignition engine is a gasoline or petrol engine which is based on the otto cycle. It uses a spark generated ...

By definition, dn/dt = - λ N ,
If you separate the variables which contain N and t, and then integrate w.r.t N and w.r.t t you get,
lnN = -λt + C (1),
...

In all collisions, provided there are no external forces, momentum is conserved. This is the law of conservation of momentum. However, kinetic energy is not conserved in all collisions. An inelastic colli...

Answer: escape velocity v = sqrt[(2GM)/r], where G is the gravitational constant.
Reasoning:
Conservation of energy means that the total initial energy must be equal to the total final energy, ...

The efficiency is calculated using the equation:
((Total useful output energy)/(Total input energy)) *100
We are essentially trying to calculate what percentage of the input energy is converted...
