Answer:
Acceleration of the meteorite, 
Explanation:
It is given that,
A Meteorite after striking struck a car, v = 0
Initial speed of the Meteorite, u = 130 m/s
Distance covered by Meteorite, s = 22 cm = 0.22 m
We need to find the magnitude of its deceleration. It can be calculated using the third equation of motion as :



So, the deceleration of the Meteorite is
. Hence, this is the required solution.
Answer:
Of the three stars in the system, the dimmest - called Proxima Centauri - is actually the nearest star to the Sun. The two bright stars, called Alpha Centauri A and B form a close binary system; they are separated by only 23 times the Earth - Sun distance.
Answer:
Angular velocity, 
Explanation:
The mass of the skater, M = 74.0 kg
Mass of each arm,
( since it is 13% of the whole body and each arm is considered)

Mass of the trunk, 

Total moment of Inertia = (Moment of inertia of the arms) + (Moment of inertia of the trunks)


The final moment of inertia of the person:

According to the principle of conservation of angular momentum:

D) Less than 20.
Explanation:
Equivalent resistance in a parallel combination is less than their individual value.
Answer:
Their is a direct relationship between the number of batteries and the increase in power. The voltage is the product of the number of batteries and the voltage which is 9 volts. As the batteries touch ends the voltages of all three combines.
