Answer:
14.68m/s
Explanation:
As per the question, the data provided is as follows
Mass = M = 0.148 kg
Height = h = 11 m
Initial velocity = U = 0 m/s
Final velocity = V
Gravitational force = F
Mass = M
Based on the above information, the speed that hit to the ground is
As we know that
Work to be done = Change in kinetic energy
= 14.68m/s
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
