Hot water, as in very hot water, goes to steam with an enormous change in volume and pressure. This is capable of driving turbine blades, which in turn rotate enormous copper (eg) wired coils in enormous magnetic fields. This in turn produces electricity via electromagnetic induction and Fleming's right hand (I think it is) DYNAMO rule. That goes down miles and mile of v heavy conducting wire/cable as electricity.

8.92 A 45.0 kg woman stands up in a 60.0 kg canoe 5.00 m long. She walks from a point 1.00 m from one end to a point I .00 m fro
omeli [17]

The distance that the canoe moves in this process is 1.29 meters.

We first have to find the center of mass

X = \frac{MsXs+McXc}{Mw+Mc} \\\\

Where

Ms = Woman's mass = 45

Mc = Canoe's mass = 60kg

Xs = position from left= 1 cm

Xc = position from left end of canoe's mass = 2.5cm

When we put these values into the equation we have:

X=\frac{45*1+60*2.5}{45+60} \\\\= 1.857\\

The center of gravity lies at the center of this boat. Therefore,

Xc = \frac{L}{2} \\\\L = 5 m long\\\\\frac{5}{2} =2.5

5.00 - 1. 00 = 4 meters

\frac{45*4+60*2.5}{45+60} = 3.14meters\\\\

To get the distance that is moved by this canoe

distance = 3.143-1.857

= 1.286

≈ 1.29 meters

The distance that the canoe moves in this process is 1.29 meters.

Convection is usually described as a ___________; when something is heated, it rises, cools, and then falls in a circular patter
creativ13 [48]

Answer:

Current

Explanation:

Convection is the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat. Simply put, Convection is the circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense — rises, while the cooler air or liquid drops down.

An everyday example of convection is boiling water ; The heat passes from the burner into the pot, heating the water at the bottom. The water at the bottom rises and is replaced by the water at the top of the pot.

This rise of less dense water at a higher temperature and fall of denser water at a lower temperature sets up a convention current circularly until the water boils. This is a typical example of the day to day application of convection currents.

The magnetic dipole moment of Earth is 8.00 ✕ 1022 J/T. Assume that this is produced by charges flowing in Earth's molten outer
KonstantinChe [14]

To solve the problem it is necessary to use the concepts and expressions related to the magnetic dipole moment.

It is usually defined by,

\mu = IA

Where,

\mu = Magnetic Dipole Moment

I = Current

A = Area

In this way re-arrange for the current and replacing,

I = \frac{\mu}{A}

I = \frac{8*10^{22}}{\pi R^2}

I = \frac{8*10^{22}}{\pi * (3350*10^3)^2}

I = 7.1285*10^9A

Therefore the current is 7.1285*10^9  Amperes
