Consult Interactive Solution 7.10 for a review of problem-solving skills that are involved in this problem. A stream of water st
AlekseyPX

Explanation:

Initial speed of the incident water stream, u = 16 m/s

Final speed of the exiting water stream, v = -16 m/s

The mass of water per second that strikes the blade is 48.0 kg/s.

We need to find the magnitude of the average force exerted on the water by the blade. The force acting on an object is given by :

F=\dfrac{m(v-u)}{t}

Here, \dfrac{m}{t}=48\ kg/s

F=48\times (-16-16)\ N\\\\F=-1536\ N\\\\|F|=1536\ N

So, the magnitude of the average force exerted on the water by the blade is 1536 N.

1.) Using Ohm’s law, explain how voltage changes in relation to current, assuming that resistance remains constant.
Harrizon [31]
1.) Ohm's law is understood as I = V/R. Given that resistance is constant, then voltage changes directly proportional to current.

2.) The more current that passes through a lightbulb, the brighter it glows. The higher the current, the higher the power, where power determines the brightness of a bulb.

3.) A bulb has a specific limit to how much power (Watts) it can handle. Going over the limit would cause the bulb to burn out.

4.) When a bulb burns out, no current will be able to pass through the filament.

What does the force of gravity between two objects depend on?
lawyer [7]

-- The equal, mutual forces of gravity between two objects depend on the product
of the two masses ... it doesn't matter whether the masses are equal or there's
one huge mass and one minuscule mass. It's the product that counts.

-- The force also depends on the distance between the centers of the two objects.
