Answer:

C. At the highest position of the bob, the KE is equal to zero.

Explanation:

When pendulum bob is at highest position then the bob is released from rest position

So at that instant of time the pendulum bob is at rest position so we can say that

initial total energy = kinetic energy + potential energy

As we have taken the ground position as reference so at the ground potential energy is zero

Since pendulum will never touch the ground position so here potential energy of pendulum never equal to zero

Now when pendulum is released its potential energy will convert into kinetic energy

So here correct answer will be

C. At the highest position of the bob, the KE is equal to zero.

Explanation:

To solve the problem it is necessary to take into account the concepts related to Period and Centripetal Acceleration.

By definition centripetal acceleration is given by

$a_c = \frac{V^2}{r}$

Where,

V = Tangencial velocity

r = radius

With our values we know that

$a_c = \frac{V^2}{r}$

$\frac{V^2}{r} = \frac{1}{10}g$

Therefore solving to find V, we have:

$V = \sqrt{\frac{1}{10}g*r}$

$V = \sqrt{\frac{9.81*200}{10}}$

$V = 14m/s$

For definition we know that the Time to complete are revolution is given by

$t = \frac{Perimeter}{Speed}$

$t = \frac{2\pi R}{V}$

$t = \frac{2\pi * 200}{14}$

$t = 1.5min$

what is the main reason that attitudes are more often revealed in spoken rather than written language

pishuonlain [190]

It's a combination of all those things. probably because we are taught from an early age to write in an academic fashion, giving balanced arguments and a conclusion. When speaking from the heart, there is no opposing argument nor is there a conclusion, just emotion.

Explain the relationship between the current output of the power supply and the current through each component in the parallel c

baherus [9]

Explanation:

Current output at the battery will be current of entire circuit, while the current through each bulb in the parallel circuit is the total current circuit.

So, current output through power supply is i and current through each component be $i_1, i_2 , i_3$ considering only three component.

Then in a parallel circuit

$i = i_1+i_2+i_3$
