Answer:
a for the first one b for the second
An adiabatic process. This occurs when there is no loss or gain of heat, as stated in the question.
Gravity is a pair of forces of attraction between every
two objects. Period !
It doesn't matter whether they're moving together, moving apart,
moving gracefully in synchrony, or at rest. The gravitational forces
of attraction between them are always there.
let the plane is flying at some angle theta with west towards north
Now we can use the components
now since plane has to fly towards west so net speed in north must be equal to speed in south for air
So we can say
so plane has to fly in direction 14.5 degree North of west
Answer
given,
mass of spring, m = 1.12 Kg
spring constant , k = 32.3 N/m
speed. v = 3.58 m/s
a) Kinetic energy of the spring
the mechanical work done by the spring
now,
A =0.666 m
Amplitude of Oscillation = 0.666 m
b) Total mechanical work done by the spring
E = 7.17 J
