Do you think it is easier or harder to hammer a nail into a floorboard on Pluto than on Earth? How about the Sun? Explain.
Serggg [28]

Explanation:

It would be easier to lift the  hammer, during the nailing, in Pluto than on earth but it would require more hammer jacks to drive the nail through the  floorboard. This is because the gravity on Pluto is weaker than on Earth. The additional acceleration of the hammer (due to gravity) would be lesser hence you would require to put in a bit more energy for the downforce of the hammer.

On the sun, it would be difficult to lift the hammer than here on earth. This is because the gravity of the sun is much greater than on earth. If you would manage to lift the hammer, the downforce of the hammer on the nail would have an added acceleration of the gravity of the sun hence the force of the hammer hitting the nail would be higher hence rapidly driving it through the floorboard.

PtichkaEL [24]

Answer:

Total time spend = 48.18 hours (Approx)

Explanation:

Given:

Total distance = 5,300 km

Average speed = 110 km / h

Find:

Total time spend

Computation:

Time = Distance / speed

Total time spend = Total distance / Average speed

Total time spend = 5,300 / 110

Total time spend = 48.18 hours (Approx)

A wheel rotates 3 times. What is its angular displacement?
tia_tia [17]

Answer:

The angular displacement would be 6 Pi radians or 1080 degrees.

Explanation:

Every individual rotation is 2 Pi (this applies to anything regardless of radius).

Since there are three rotations you are going to multiply 2 Pi by 3.

This will give you 6 Pi which you can convert to equal 1080 degrees (1 Pi = 180 degrees).

5.37 At steady state, a power cycle develops a power output of 10 kW while receiving energy by heat transfer at the rate of 10 k
Anika [276]

Answer: minimum theoretical value of T = 750k

Explanation:

Assuming the the cycle is reversible and is ideal then

Wnet/Qh = Nmin .... equa 1

Equation 1 can be rewritten as

(Th -TL)/ Th ...equation 2

Th= temp of hot reservoir

TL= temp of low reservoir= 300

Wnet = power generated=10kw

He = energy transfer=10kj per cycle

Qhe = power transfer = (100/60)*10Kj = 16.67kw

Sub into equat 1

Nmin = 10/16.67 = 0.6

Sub Nmin into equation 2

Th = -TL/(Nmin -1) = -300k/(0.6 - 1)

Th =750k
