A city is considering switching to geothermal power for their electricity needs. Which of the following is an advantage of this
quester [9]

It uses water to power large turbines.

Geothermal power taps on the energy of natural steam from the earth's lithosphere.

Explanation:

The heat from deep in the the lithosphere heats up underground water into high-pressure steam trapped in within the rocks. Boreholes are sunk to tap on the potential energy of this high-pressure steam to turn large dynamo turbines that convert the steam energy into electricity.

The biggest advantage, moreover, is the fact that this method of electricity generation does not emit greenhouse emissions as compared to gas plants that burn hydrocarbons that release CO₂.

finlep [7]

Answer:

C. 3,200

Explanation:

MA= F out/ F in.

multiply F in on both sides to cancel it out so you can solve for F out.

Fin*MA=F out

400 * 8 = F out

3,200= F out

The mass of a lift is 600kg.the. The maximum tensile force that the cable supporting the lift can withstand is 7kN. Calculate th
Oksi-84 [34.3K]
Force is the product of mass and acceleration .
The question is ask to find acceleration.
But acceleration is the ratio of the force and the mass.
where 600kg is the mass and 7kN is the force
NB: kilo is 1000
now we have to multiply 7N by 1000
by doing so you will have 7000N
which is the force.
Now to find the acceleration: force/ mass
which is 7000/600
therefore the maximum acceleration is 11.667
