Answer:
Change in Kinetic Energy is
Solution:
As per the question:
Mass of space craft,
Mass of the sun, M =
Radius of the orbit, R =
Radius of smaller orbit around the sun, r =
Now,
We know that the Gravitational Potential Energy is given by:
where
G = Gravitational constant
r = distance of the space craft from the center of the sun
Now,
Initial Gravitational Potential Energy is:
Now,
Final Gravitational Potential Energy is:
Change in the Gravitational Potential Energy equals the change in the kinetic energy of the space craft.
Thus
The answer is true to your question
Answer:
C) volts
Explanation:
f = frequency of oscillator = 1 kHz = 1000 Hz
= 12 Volts
L = Inductance of Inductor = 5 mH = 0.005 H
= Inductive reactance
Inductive reactance is given as
=
=
= Capacitive reactance
Capacitive reactance is given as
Impedance of the circuit is given as
Rms Current flowing is given as
A
Rms potential difference across the resistor is given as
volts
When solar radiation reaches the Earth it quickly dissipates as most of the radiation and UV rays are blocked by ozone layer, but more radiation and UV rays are able to get through because of global warming.
