Since the two colliding objects travel together in the same direction after the collision, the total momentum is simply the total mass of the objects multiplied by their velocity
Answer:
Meter marks are on cut-off portion of stick is 100 - 60 = 40 m
Explanation:
Given data:
Spaceship length of L = 100 m
Relative velocity between the ship and stick is given as
The observed length observed by the outside observer is
putting all value to get observe length
put
L' = 60 m
Meter marks are on cut-off portion of stick is 100 - 60 = 40 m
The Terra satellite was sent to space on <span>December 18, 1999 and is still there in 2016. The satellite is able to monitor volcanic eruptions on Earth. The correct answer is D. </span>
Answer: 99.64 nm (≅ 100 nm)
Explanation: In order to explain this problem we have to obtain destructive inteference from two waves that reflect in the film and lens surface so both waves have a λ/2 shift then we have to get a difference path (2L) equal to an odd number of the half wavelegth.
Then we have the following expression:
L=(m+1/2)* λ/(2*n2); where n2 is the refractive index of the coating
for m=0 we have the minimum thickness for the coating
L=λ/(4*n2)=99.64 nm (≅ 100 nm)
