Answer:D
Explanation:
Given
mass of A is twice the mass of B half the velocity of B
Suppose 
and 
be the average force exerted on A and B respectively
and According to Newton third law of motion Force on the body A is equal to Force on body B but opposite in direction as they are action and reaction force.
Thus 
and option d is correct
Answer:
Gas giants rotate faster than those of earth .
The correct answer for the given question above would be option B. CONCORD. According to Thomas Gage's spies, the town in which the minutemen had been collecting a large amount of arms is in Concord. The minutemen are civilian colonists who established an independent organization forming a <span> well-</span><span>prepared militia. Hope this answers your question.</span>
Answers:
1) 
2) 
Explanation:
1) Acceleration 
is defined as the variation of Velocity 
in time 
:
(1)
A body also has acceleration when it changes its direction.
In this case we have a bus with a velocity of 60m/s to the east, that accelerates in a time 10s. So, we have to find the bus's acceleration:
(2)
(3) This is the bus's accelerration
2) Now we have a car that accelerates 
to the west in order to reach a speed of 
in the same direction, and we have to find the time it takes to the car to reach that velocity.
Therefore we have to find from (1):
(4)
(5)
Finally:
(6)
