Answer:
-2.66 kJ
Explanation:
At constant pressure, work done is:
W = -P ΔV
W = -(95.000 Pa) (43 m² − 15 m²)
W = -2660 J
W = -2.66 kJ
A generator converts mechanical energy into electrical energy, while a motor does the opposite - it converts electrical energy into mechanical energy
Answer:
= 15 m/s
Explanation:
Considering right side(west) as positive x-axis and south as negative y-axis.
velocity of boat in still water 
velocity of stream 
now relative velocity of boat w.r.t. stream 
this velocity with which ac distance will be covered.
therefore magnitude of 
= 15 m/s
Newton stated 3 laws that rules moving bodies:
First law - an object remains in its state (resting or moving at constant speed) unless acted upon a force
Second law - the force (F) of an object is equal to its mass (m) multiplied by its acceleration (a); F = m x a
Third law - when an object exerts a force upon another, the second object exerts a force that is equal in magnitude and opposite in direction
So, according to the First Law of Motion, the metor moving through outer space will continues its motion until an outside force acts upon it
