A mirror can just reflect light rays with an angle, it can't be parallel. or if light is perpendicular to the surface of mirror, then it will reflect for same path
In short, Your Answer would be Option C
Hope this helps!
Answer:0.5
Explanation:
Given
Piece of taffy slams in to sticks to another identical piece and stuck into it.
Let m be the mass of taffy and u be the initial velocity of taffy and v be the final velocity of system.
Conserving momentum
Initial kinetic energy
Final Kinetic Energy
change in kinetic energy
change in kinetic energy will contribute in heat energy
thus fraction of kinetic energy converted in to heat
Answer:
F= 12 N
Explanation:
Given that
Work done by student ,W= 60 J
The mass of the box ,m = 3 kg
Length ,x = 5 m
We know that ,The work done by a force a force F is given as
W= F .x
x=Displacement
F=Force
W=Work
Now by putting the values
60 = F x 5
F= 12 N
That is why the magnitude of the force will be 12 N.
