Answer:
The final speed of puck 1 is 0.739 m/s towards west and puck 2 is 2.02 m/s towards east .
Explanation:
Let us consider east as positive direction and west as negative direction .
Given
mass of puck 1 ,
mass of puck 2 ,
initial speed of puck 1 ,
initial speed of puck 2 ,
Final speed of puck 1 and puck 2 be respectively
Apply conservation of linear momentum
=>
=> -----(A)
Since collision is perfectly elastic , coefficient restitution e=1
=> ------(B)
From equation (A) and (B)
and
Thus the final speed of puck 1 is 0.739 m/s towards west and puck 2 is 2.02 m/s towards east .

Answer:
Answer to the question as below
Explanation:
In all four H-R diagrams, first we look at the diagram which is at the left and it represents the Sun; it may be any other one solar mass star as a hydrogen burning main sequence star, with spectral type G and one solar luminosity.
In the next diagram it shows that the Sun after it has exhausted its core hydrogen and left the main sequence, making it a sub-giant with energy generated by hydrogen burning in a shell around an inert helium core.
Look into the third diagram which shows the Sun a little later; its energy source is still hydrogen shell burning, but at this point it has expanded in size so much that it is a red giant.
In the final diagram which is located at far right; it shows the white dwarf corpse of a one-solar-mass star; it is hot because it is the exposed core of the dead star, but dim because it is small in size.
Answer:
B
Explanation:
Current is only measured in Amperes.
D makes little to no sense and I believe A somewhat relates to static electricity, not current.
Answer:
I think its 12 cm itself. Because in the question it is said that the length is same in all temperature
