Answer:
The answer to your question is: The distance traveled by light in one year.
Explanation:
A light year is a unit of distance.
Answer:
No
Explanation:
According to physics, the work done by porter is zero but in reality porter gets tired as muscular energy is being used up.
In physics, work is the dot product of force and displacement. when the porter moves with the luggage, the weight act downwards while the porter moves forward. The angle between force and displacement is 90°. Thus, work done by the porter is zero.
The muscles are doing work in this case which is not calculated in physics.
Power is the rate of energy consumed during the work.
Answer:
The magnitude will be "2212 N".
Explanation:
The given values are:
Initial speed, u = 250 m/s
Final speed, v = 0
Mass, m = 16.0 = 0.016 kg
Distance, d = 22.6 cm
On converting cm into m, we get
d = 0.226 m
As we know,
⇒ 
⇒ 
On putting the estimated values, we get
⇒ 
⇒ 
⇒ 
Now,
Force, 
On putting values, we get
⇒ 
⇒
(magnitude)

The two pictures attached here shows the solution to the two questions from the problem. thank you and I hope it helps you
I think the answer is a although I'm not 100% sure. I think it's becuase it's natural and nothing man made has ever intervened with it
