Object a attracts object b with a gravitational force of 10 newtons from a given distance. if the distance between the two objects is doubled,
what is the new force of attraction between them?
a
2.5 newtons
b. 5 newtons
c. 20 newtons
od. 100 newtons

Decreased sensitivity to an unchanging stimulus is known as

1) what is the power in horsepower of a 100 watt light bulb? what is the power in kilowatts of a 200 horsepower engine? 2) if a cars engine is providing 3000 n of force to keep the car moving at 5 m/s, what is the engine’s effective power? 3) how many gallons of water will be pumped from a well 30 feet deep by a 1/2 hp engine in 1 minute? (1 gallon weighs 8.34 pounds)

The resistance of 100 w bulb is less than resistance of 40 w bulb. explain the reason.
