Answer:
If you run a 500 W computer for 4 hours, your electric meter will read 2kWh; this is a measure of energy "used". The correct answer is D.
Explanation: Energy is defined as the capacity of doing work and is occurs in different forms( electrical, kinetic, potential energy). Electrical energy consumption can be calculated or measure through the multiplication of the power( W or kW) used by the number of hours during which the power is consumed. Therefore the unit of energy is kWh. From the question,
500W was used for 4 H
Therefore energy consumed
500× 4= 2000Wh. To convert to kWh
Divide by 1000,
2000÷ 1000= 2.
There energy consumed in kWh is,
2kWh energy.

Explanation:
The gravitational force of the earth keeps us bound to the earth. Gravitational force between earth and sun makes the earth move around the sun. Gravitational force between moon and earth makes the moon go around the earth.
Answer:
149.34 Giga meter is the distance d from the center of the sun at which a particle experiences equal attractions from the earth and the sun.
Explanation:
Mass of earth = m =
Mass of Sun = M = 333,000 m
Distance between Earth and Sun = r = 149.6 gm = 1.496\times 10^{11} m[/tex]
1 giga meter =
Let the mass of the particle be m' which x distance from Sun.
Distance of the particle from Earth = (r-x)
Force between Sun and particle:
Force between Sun and particle:
Force on particle is equal:
F = F'
= ±577.06
Case 1:
x =
Acceptable as the particle will lie in between the straight line joining Earth and Sun.
Case 2:
x =
Not acceptable as the particle will lie beyond on line extending straight from the Earth and Sun.
Answer:
not moving
static actually means lacking in movement or action❤
Answer:
45 takes less energy and is less stronger light than a 60 watt bulb, but a 60 watt bulb is stronger and takes more energy.
