Answer:Momentum
Explanation:
Product of an object mass and velocity is called Momentum. Basically momentum is the measure of mass in motion . More is the mass more will be the momentum and similar applies for velocity.
For example a bus moving with low velocity can have a same momentum as that of a bullet moving with a very high velocity
Momentum is denoted by Symbol P

Answer:
Speed of the aircraft = 36.64 m/s
Explanation:
Consider the vertical motion of the projectile,
We have equation of motion s = ut+0.5at²
Let the velocity of plane be v.
Vertical velocity = vsin55 = Initial velocity of projectile in vertical direction = u
acceleration, a = 9.81 m/s²
displacement , s = 554 m
time, t = 8 s
Substituting,
554 = vsin55 x 8 +0.5 x 9.81 x 8²
v = 36.64 m/s
Speed of the aircraft = 36.64 m/s
Answer:
a long time after the switch is closed
Explanation:
Energy stored in an inductor is given by
E = 1/2 L i²
A). Before the switch is closed the current in the circuit is zero so energy in inductor will be zero.
B). Inductor opposes the flow of current. It takes some time for current to reach its maximum value. So immedialtly after closing the switch the current and energy in inductor will still be zero.
C). After closing the switch it takes some time for current to reach its maximum value as inductor opposes the flow of current. so after a long time the current in inductor will reach its maximum value and hence the energy stored will be maximum.
