To solve this problem we will apply the concepts related to the relationship between the voltage, the electric field and the distance, once the voltage is found we will use the definition of power, which is defined as the square of the voltage over the resistance. This is,

E = Electric field
d= Distance between the points
Replacing,


Now applying the relation for power we have,

Here
V = Voltage
R = Resistance
Replacing,


Therefore the total power emmited by the transmitter is 224509.3 W
Answer:
false, each force might have a different about and a different direction
Initial velocity = 25 m/s, angle 60°
sin (60°) = opposed leg / hypothenuse = Vertical velocity / Initial velocity
=> Vertical velocity = initial velocity * sin (60°) = 25 m / s * 0.866 = 21.65 m/s
B-friction acts in direction opposite to objects motion
