Answer:
25 mm = 0 deg C
200 mm = 100 deg C
200 - 25 = 175 = change in thread per 100 deg C
95 - 25 = 70 mm - change in thread from 0 deg C
70 / 175 * 100 = 40 deg C final temperature at 95 mm
Answer:
0.85 c
Explanation:
When the two travel at right angles to each other , their relative velocity is given by the hypotenuse formed by the x and y direction velocities.
Relative velocity of the two protons is given as
If v = 3/5 c , then the relative speed = 
(3/5c) =0.85 c
Fixed volume and shape
-Particles are locked into place
Not easily compressible
-Little free space between particles
Does not flow easy
-Particles cannot move past each other
B. A copper wire with rubber insulation
Newton taught us that Force = (mass) x (acceleration)
Force = (0.2) x (20) = <em>4 newtons</em> .
Something to think about: The ball can only accelerate while the club-face
is in contact with it. Once the ball leaves the club, it can't accelerate any more,
because the force against it is gone.
