Answer:
it does use it at doppler
Explanation:
My dad told me the hes a cop so yw
m = mass of water in bathtub = 62.7 kg
= initial temperature of water in tub = 31 c
M = mass of water added = ?
= initial temperature of water added = 76 c
T = final equilibrium temperature of the system = 40.3 c
c = specific heat of water = 4186
Using conservation of heat
Heat gained by water in tub = Heat lost by water added
m c (T - ) = M c ( - T)
m (T - ) = M ( - T)
(62.7) (40.3 - 31) = M (76 - 40.3)
M = 16.3 kg
When an electric current is flowing through a wire, there is a magnetic <em>field</em> produced. The lines of magnetic force are circles around the wire.
A table would be the most appropriate because that way you can compare the data.
Answer:
Slip Rings
Explanation:
The wound rotor motor has a three-phase winding with each one connected to seperate slip rings. These slip rings contain brushes which form a secondary circuit where resistance can be inserted and this will allow for the rotor current to run more in phase with the stator current which will result in increased torque that is created
