Pendulum A has a bob of mass m hung from the string of length L; pendulum B is identical to A except its bob has the length 2L.

GenaCL600 [577]

Answer:

$f_{B}: f_{A} = \sqrt{\frac{2}{1}}$

Explanation:

For pendulum A: Length = L and gravity = g

The frequency of pendulum A is given by

$f = \frac{1}{2\pi }\sqrt{\frac{g}{L}}$

Here, f is the frequency, L be the length

$f_{A} = \frac{1}{2\pi }\sqrt{\frac{g}{L}}$ ... (1)

For pendulum B: Length = 2L, gravity = g

The frequency of pendulum B is given by

$f_{B} = \frac{1}{2\pi }\sqrt{\frac{g}{2L}}$ .... (2)

Divide equation (1) by (2)

$f_{B}: f_{A} = \sqrt{\frac{2}{1}}$

Which of the following is a declarative sentence

arsen [322]

Any multiple choice? I cant answer without possible answers.
But for insight a declarative sentence is a statement. For example: "I am going to the store." And Declarative sentences end with a period. (.)
Hope this helps. Just dont get confused with sentences that end in periods (.) but are really commands.

Which statement is true about the speed of heat transfer by conduction?

antiseptic1488 [7]

Answer:

Conduction is fastest in solid

Explanation:

A basic property of conduction is that for heat to transfer there must be contact. From kinetic theory, configuration of solid is such that the molecules are held together and they move or vibrate about their mean position. Because of this arrangement heat transfer by conduction is faster in solid that any other state of matter

In an RL series circuit, an inductor of 3.54 H and a resistor of 7.76 Ω are connected to a 26.6 V battery. The switch of the cir

podryga [215]

Answer:

Energy stored in inductor will be 20.797 J

Explanation:

We have given inductance L = 3.54 H

And resistance R = 7.76 ohm

Battery voltage V = 26.6 VOLT

After very long time means at steady state inductor behaves as short circuit

So current $i=\frac{V}{R}=\frac{26.6}{7.76}=3.427Amp$

Now energy stored in inductor $E=\frac{1}{2}Li^2=\frac{1}{2}\times 3.54\times 3.427^2=20.797J$

So energy stored in inductor will be 20.797 J
