Answer:
Explanation:
<u>Given Data:</u>
Momentum = P = 700 kg m/s
Velocity = v = 10 m/s
<u>Required:</u>
Mass = m = ?
<u>Formula:</u>
P = mv
<u>Solution:</u>
m = P / v
m = 700 / 10
m = 70 kg

Answer:
The current in primary coil is 2.08 A.
Explanation:
Given that,
Power = 500 W
Voltage = 16 kV
Number of turns = 80000
We need to calculate the number of current
Using formula of voltage
Put the value into the formula
We need to calculate the current in secondary coil
Using formula of current
We need to calculate the current in primary coil
Put the value into the formula
Hence, The current in primary coil is 2.08 A.
I think fluids travel faster near the center of pipes and tubes better than at the edges because they are able to travel much faster, and smoother in the center rather than the edges because the fluids have to turn, which could cause the rest of the incoming fluids to stop, which would make it much slower when traveling through the edges than through the center.
The speed of the disturbances in The waves should remain the same since they are all electromagnetic waves (C=3*10^8m/s)
Answer:
can a fire have a shadow?
Yes it can actually.
edit:Fires can have shadows because they contain hot air and soot, and not because they contain light.
