The batteries being made from a common nonrenewable resource is the

reason why modern rechargeable batteries are expensive.

<h3>What is a Non-renewable resource?</h3>

Non-renewable resource are those in which it is very difficult to replace

them easily through natural methods. This makes it hard to meet up with

customer's use.

This thereby makes it very expensive and not able to meet up with

customer's needs. This is why renewable sources are more preferable.

An ideal gas is maintained at a constant pressure of 70,000 Pa during an isobaric process and its volume decreases by 0.2m^3. Wh
Svetach [21]

Answer:

c. -14,000

Explanation:

Workdone by gas is the product of the pressure and the volume where there is a change of volume.

If v1 is the initial volume of the gas and v2 is the final volume of gas, the work done

= p(v2 - v1)

where p is the pressure

and p = 70,000 Pa

Given that volume decrease by 0.2m^3, v2 - v1 = -0.2

Workdone = 70000 ( -0.2)

Workdone = -14,000 J

Option c. -14,000

Can someone help me find the which direction is north and which is south on this solenoid?
arsen [322]

Explanation:

Now, looking down the solenoid tube determine what direction is the winding. If clockwise in relation to the positive wire then is the south pole, if anti-clockwise then is the north pole. So, to summarize the magnetic south pole is always clockwise in relation to the positive wire.

A horizontal force pushes a 26 kg sled along a driveway for a distance of 36 m. If the coefficient of sliding friction is 0.2, w
SVETLANKA909090 [29]

Answer:1834.56 joules

Explanation:

Distance=36m

Coefficient of friction=0.2

Mass=26kg

Acceleration due to gravity=9.8m/s^2

Reaction=mass x acceleration due to gravity

Reaction=26 x 9.8

Reaction=254.8N

Coefficient of friction=frictional force ➗ reaction

0.2=frictional force ➗ 254.8

Frictional force=0.2 x 254.8

Frictional force=50.96N

work=friction force x distance

Work=50.96 x 36

Work=1834.56

Work=1834.56 joules
