Answer:

Answer:

White Stern light

Explanation:

According to boating regulations, navigation lights must be used for safety purposes when operating water vessels especially during the night.

The boating regulations for operating sailboats, specify that a white stern light must be used during hours from sunset to sun rise. This is to indicate the presence of the sea craft on the ocean, as well as its direction.

A stern light is a white light placed as closely as practical at the stern shining constantly. It covers an angle of 135 degrees, and helps show the direction of the boat.

A guy named Kirby Had touched only a gear on the projector. Yet there was a out of the blue rip. Kirby did not mind at all and started the projector. Things went wrong and the tape would not work. What ripped?

Answers

The guy named Kirby didn't touch the power button on the projector. If he touched means the projector will work fine.

Explanation:

  • Kirby touched the gear on the projector. He should check the projector carefully before operating the projector. But he didn't check properly.
  • There was a blue rip in the projector. Kirby fails to notice the blue rip. Without minding that he has started the projector. So the tape and the projector is not working well.
  • He should fix the blue rip and he should press the start button in the projector. The mistake is he didn't do that. This is the thing that made the projector ripped.

Only option a and the option b follows the first law of thermodynamics.

Explanation:

As we know that the first law of  thermodynamics tells the conservation of energy, that is why it is also called quantitative law.

From the first law of thermodynamics  

Q=\Delta E+W

a.  Given that

W= 50 KJ,Q = 170KJ ,ΔE = 120 KJ

Yes, this follows the first law of  thermodynamics.

b.  Given that

W= 100 Btu,Q= -110 Btu ,ΔE= -210 Btu

This also satisfy the  first law of  thermodynamics.

c.  Given that

W= 250 KJ,Q= -110 KJ ,ΔE=-100 KJ

Yes this does not follow the first law of  thermodynamics.

d.  Given that

Yes, this does not follow the first law of  thermodynamics.
