Answer:
Energy loss per minute will be
Explanation:
We have given the star produces power of
We know that 1 W = 1 J/sec
So
Given time = 1 minute = 60 sec
So the energy loss per minute
We multiply with 60 we have to calculate energy loss per minute
Answer:
velocity = 472 m/s
velocity = 52.4 m/s
Explanation:
given data
steady rate = 0.750 m³/s
diameter = 4.50 cm
solution
we use here flow rate formula that is
flow rate = Area × velocity .............1
0.750 = × (4.50×
)² × velocity
solve it we get
velocity = 472 m/s
and
when it 3 time diameter
put valuer in equation 1
0.750 = × 3 × (4.50×
)² × velocity
velocity = 52.4 m/s
