Answer:
heat from the sun comes on the earth by radiation
An amplifier.
Electrical energy provided to an amplifier is converted into sound energy as it is "fed" or provided to the speaker portion of an amplifier.
Answer:
The door will move when the forces exerted by each individual becomes unbalanced.
Explanation:
The Door will only move when the forces exerted by each of the individual is unbalanced i.e. when the Torque is unbalanced
This is because there will only be a reaction or movement of an object when the applied force > resistant force acting on the object.
example : An object at rest will only move when the applied force is greater than the frictional forces acting on the object at rest.
Answer: 0.5Amps
Explanation:
Voltage of light bulb = 120 volts
Resistance = 240Ω
Current, I = ?
Now recall that voltage = current x resistance
i.e V = I x Rtotal
120volts = I x 240Ω
I = 120 volts / 240Ω
I = 0.5amperes
Thus, there is 0.5 Amperes of current in the light bulb.
