Answer
given,
mass of student = 60 Kg
mass of suitcase = 10 Kg
a) Work done by picking of Suitcase is equal to zero
b) acceleration = 0.1 m/s²
distance = 2 m
Using second law conservation
F = m a
F = 10 x 0.1 = 1 N
c) Work done
W = F x s
W = 1 x 2 = 2 J
d) When the are moving with constant speed acceleration is equal to zero
F = m a
F = 10 x 0 = 0 N
W = F x s = 0 x s = 0 J
e) work done = change in kinetic energy
K.E = 2 J

Answer:
The maximum power density in the reactor is 37.562 KW/L.
Explanation:
Given that,
Height = 10 ft = 3.048 m
Diameter = 10 ft = 3.048 m
Flux = 1.5
Power = 835 MW
We need to calculate the volume of cylinder
Using formula of volume

Put the value into the formula


We need to calculate the maximum power density in the reactor
Using formula of power density

Where, P = power density
E = energy
V = volume
Put the value into the formula


Hence, The maximum power density in the reactor is 37.562 KW/L.
I think the answer would be c
