Air bags are kept in the steering wheel or
dashboard and expand during a serious collision, usually a front collision that
occurs at over 10 mph. To do its important job, an air bag comes out of the
dashboard at up to 200 mph, faster than the blink of an eye. It is estimated
around 10 inches of space to inflate. The force of an air bag can hurt those
who are too close to it. Driver and front seat passengers should be
moved as far back as practical, mainly people of short built. It is highly suggested
that you be seated no less than 10 inches away from the air bag. Therefore, the answer is letter b.
Yes, the above-given statement is true
<u>Explanation:</u>
- The product of the mass x the velocity will be the same for both. Momentum is the action of a body with a particular mass through space and there is the conservation of momentum.
- Momentum is described as the mass of the object multiplied by its velocity.
- <u>Momentum (p) = Mass (M) * Velocity (v)</u>
- Therefore for two objects with many masses to have a similar momentum, then the lighter one has to be moving quicker than the heavier object.
A :-) F = mv^2 by t
Given - m = 10 kg
r = 10 m
v = 10 m/s
Solution -
F = mv^2 by t
F = 10 x 10^2 by 10
F = 10 x 100 by 10
( cut 10 and 10 because 10 x 1 = 10 )
F = 100 N
.:. The centripetal force is 100 N
It’s true now say thank you
