Velocity can be calculated using the following rule:
velocity = lambda * frequency where:
velocity is given = 6 km/sec
lambda is the wavelength that we want to calculate
frequency is given = 13 Hz
Substitute with the givens in the above equation to get the wavelength (lambda) as follows:
6 = 13*lambda
wavelength = 6/13 = 0.461538 Km = 461.538 meters
Answer:
195
Explanation:
he can only apply as much force as his body mass so it would be 195
<em>Kinetic (mechanical) energy</em>
Answer:
Explanation:
Given that,
Charge through a wire is
Q = 4000C
Time for charge to pass through the wire is
t = 50seconds
Then,
Current through the wire is the rate of charge passing through the wire
Q = it
Where
Q is charge.
I is current
t is time taken
Therefore,
I = Q / t
I = 4000 / 50
I = 80 Amps
