Answer:
422.36 N
Explanation:
given,
time of rotation = 4.30 s
T = 4.30 s
Assuming the diameter of the ring equal to 16 m
radius, R = 8 m
v = 11.69 m/s
now, Force does the ring push on her at the top
N = 422.36 N
The force exerted by the ring to push her is equal to 422.36 N.
Answer
given,
high temperature reservoir (T_c)= 464 K
efficiency of reservoir (ε)= 25 %
temperature to decrease = ?
increase in efficiency = 42 %
now, using equation
T_C = 348 K
now,
if the efficiency is equal to 42$ = 0.42
