Answer:

Though lightning can be harvested in a safe manor, it is not very practical in many areas. Not all places get lightning storms in high amounts, so those locations would not apply, but those who do see frequent lightning can indeed use it to power. Using tall metal beams can attract the lightning and can be escorted into a power converter much like the ones used for nuclear energy.

Transverse waves travel with a speed of 20 m/s on a string under a tension 0f 6.00 N. What tension is required for a wave speed

Aleksandr [31]

Answer:

$T_2=13.5\ N$

Explanation:

Given that,

Speed of transverse wave, v₁ = 20 m/s

Tension in the string, T₁ = 6 N

Let T₂ is the tension required for a wave speed of 30 m/s on the same string. The speed of a transverse wave in a string is given by :

$v=\sqrt{\dfrac{T}{\mu}}$ ........(1)

T is the tension in the string

$\mu$ is mass per unit length

It is clear from equation (1) that :

$v\propto\sqrt{T}$

$\dfrac{v_1}{v_2}=\sqrt{\dfrac{T_1}{T_2}}$

$T_2=T_1\times (\dfrac{v_2}{v_1})^2$

$T_2=6\times (\dfrac{30}{20})^2$

$T_2=13.5\ N$

So, the tension of 13.5 N is required for a wave speed of 30 m/s. Hence, this is the required solution.

Explain why it is important that the balloon is made from an electrical insulator.

aleksandr82 [10.1K]

Explanation:

object made of rubber, such as the ballons are elecrical insulators, meaning that they resist electric charges flowing through them..

when the ballon has been rubbed enough times to gain a sufficient negative charge, it will be attracted to the wall

A charge of 1. 5 µC is placed on the plates of a parallel plate capacitor. The change in voltage across the plates is 36 V. How

ELEN [110]

It is a type capacitor is in which two metal plates arranged in such a way so that they are connected in parallel . The potential energy is stored in the capacitor will be 2.7×10⁻⁵.

<h3>What is parallel plate capacitor ?</h3>

It is an type capacitor is an in which two metal plates arranged in such a way so that they are connected in parallel and have some distance between them.

A dielectric medium is a must in between these plates. helps to stop the flow of electric current through it due to its non-conductive nature .

The given data in the problem is;

Q is the charge= 1.5 µC

V is the change in voltage across the plates is = 36 V.

U is the potential energy=?

The formula for the potential energy is given by;

$\rm U= \frac{1}{2} \times Q \times V \\\\ \rm U= \frac{1}{2} \times 1.5\times 10^{-6} \times 36 \\\\ \rm U=2.7\times10^{-5}$

Hence the potential energy is stored in the capacitor will be 2.7×10⁻⁵.

An electron and a proton are both released from rest, midway between the plates of a charged parallel-plate capacitor. The only

topjm [15]

Answer:

Explanation:

Let the potential difference between the middle point and one of the plate be ΔV .

electric potential energy will be lost and it will be converted into kinetic energy .

Electrical potential energy lost = Vq , where q is charge on charge particle .

For proton

ΔV× q = 1/2 M V² ( kinetic energy of proton )

where M is mass and V be final velocity of proton .

For electron

ΔV× q = 1/2 m v² ( kinetic energy of electron )

where m is mass and v be final velocity of electron . Charges on proton and electron are same in magnitude .

As LHS of both the equation are same , RHS will also be same . That means the kinetic energy of both proton and electron will be same

1/2 M V² = 1/2 m v²

(V / v )² = ( m / M )

(V / v ) = √ ( m / M )

In other words , their velocities are inversely proportional to square root of their masses .
