Answer:
Explanation:
at
b) PE fraction = 1/36 = 0.02777
c) 1/2*KX^2 = 1/2*K*(A^2-X^2)
=> X = A/sqrt(2)
The power of the antenna is
and since the power is the emitted energy divided by the time, the energy emitted per second is
The frequency of the emitted photons is
So the energy of a single photon is
Therefore, to find the number of emitted photons per second, we should divide the total energy emitted by the antenna in 1 second by the energy of a single photon:
Answer:
Force = mass × acceleration
Explanation:
The amount of force required to drag the object across the table is the product of the mass of the object and acceleration
Answer:
so the distance between two points are
Explanation:
Surface charge density of the charged plane is given as
now we have electric field due to charged planed is given as
now we have
now for the potential difference of 100 Volts we can have the relation as
Distance = (15 minutes) x (60 sec/min) x (2 meter/sec)
Distance = (15 x 60 x 2) (minute-sec-meter / min-sec)
Distance = <em>1,800 meters </em>
