Light energy is defined as how nature moves energy at an extremely rapid rate, and it makes up about 99% of the body's atoms and cells, and signal all body parts to carry out their respective tasks. An example of light energy is the movement of a radio signal.
Answer:D.Refractive Indez
Explanation:
It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".

Answer:
The voltage of the generator is 88.53volts
Explanation:
The voltage across the RLC AC circuit will be the voltage across the generator. It is expressed as
V = IZ and
Z² = R² + (Xl-Xc)²
Z = √R² + (Xl-Xc)² where;
Z is the impedance that oppose the flow of current in the resistor, capacitor and inductor in the circuit
I is the total current = 0.312A
R is the resistance in the circuit = 280ohms
Xl is the inductive reactance = 508ohms
Xc is the capacitive reactance = 315ohms
Substituting to this parameters to get the impedance Z we have;
Z = √280²+(508-315)²
Z = √208²+(193)²
Z = √80,513
Z = 283.75ohms
The voltage V of the generator = current × impedance
V = 0.312×283.75
V = 88.53Volts
The voltage if the generator is 88.53volts
Work = (force) x (distance)
Work = (300 N) x (30 m) = <em>9,000 joules</em>
Power = (work) / (time)
Power = (9,000 joules) / (3 sec) = <em>3,000 watts</em>
Oops. I didn't use the mass of the 145-kg object.
Probably because I didn't need it.
