Answer:
Explanation:
Given
Velocity of jet relative to the carrier
Velocity of jet carrier to the wind
Velocity of wind
Length of runway=126 m
thus =20.11+8.94=29.05
=29.05+45=74.05 m/s
to find acceleration
here u=0,v=74.05 m/s
case -2
Velocity of jet relative to the carrier
Velocity of jet carrier to the wind
Velocity of wind
Length of runway=126 m
here u=0,v=77.7 m/s
An object's momentum will change if there is a non-zero net external force acting on it. This assertion is true.
<h3>
</h3><h3>What is momentum?</h3>
The momentum is defined as the product of mass and the velocity of the body. It is denoted by the letter P. It occurs due to the applied force. Its unit is Kg m/s².
p=mΔV
If there is a change in the velocity there must be a force acting on the object.
If an object is acted on by a non-zero net external force, its momentum will not remain constant. is an accurate statement.
<h3>
</h3>
Hence, option B is correct.

Answer:
14 hours 18 minutes.
Explanation:
ratio of number of orbits, so it completes 7 orbits in the time Janus does 6.
(16*60+41)*6/7=858 minutes or 14 hours 18 minutes
