Imagine you transfer heat into a gas. This heat splits up in two different ways: Additional thermal energy making the gas hotter

and “fuel” for the gas to do work. Let’s suppose, 64% of the transferred heat transforms into thermal energy. How many percent of the initial heat can be used to do work?

Answer:

  • <u>36% of the initial heat can be used to do work.</u>

Explanation:

The initial heat is the 100%, i.e. it is all the heat that will be transferred.

It wil be transferred into two different kinds of energy:

  • additional thermal energy that will increase the thermal energy of the gas, making it hotter. Call it U. U = 64%. And,

  • "fuel" for the gas to do work. Call it W.

Then,

  • 100% = U + W
  • W = 100% - U
  • W = 100% - 64% = 36%

That is, 36% of the initial heat is available to do work.

Assume that a 4.00 kg pendulum bob is hanging from a 7.90 m long cable. The cable is attached to a hook in the ceiling 10 m up f
leonid [27]

Answer:

Explanation:

Given

mass of Pendulum m=4 kg

Length of cable= 7.90 m

Distance between roof and Floor=10 m

mg\sin\thetawill Provide Torque

thus mg\sin \theta \times L=I\cdot \alpha

where I=moment of inertia

\alpha=angular acceleration

here \thetais small therefore \sin \theta \approx \theta

\frac{g}{L}\theta =\alpha

thus \omega ^2=\frac{g}{L}

\omega =\sqrt{\frac{g}{L}}

And T\cdot \omega =2\pi

T=2\pi \sqrt{\frac{L}{g}}

T=2\pi \sqrt{\frac{7.90}{9.8}}=5.64 s

Small angle refers to any angle where

\sin \theta \approx \thetai.e. any angle less than 15^{\circ}
