Term1/4

An atom of 134 84 PO decays by alpha decay Which atom is left after the decay

Term1/4

For a stationary observer when the source of a sound is moving its

Definition1/4

When the source of a sound moves, the frequency noted by the observer will change. This is an example of Doppler's law.

answer: its pitch appears to change.

Term1/4

If the boats engine has a heat input of 40000 J with 30000 J exhausted into the surroundings the heat sink what is its efficiency

Definition1/4

efficiency = output/input

therefore, in above case it is 3/4= 0.75

or 75%.
