Answer:

d) F

Explanation:

According to columb's law:

"The magnitude of electrostatic force between two charges is directly proportional to the product of magnitude of two charges and inversly proportional to separation between them."

If q₁ and q₂ are magnitude of two charges, d is distance between them and k is dielectric constant, then force F is given by

                                               

                                              F=\frac{kq_{1}q_{2}}{d^2}

According to this force exerted on point charge Q is same as that of 3Q, so force point 3Q charge experience is also F

As you watch the surfers right away towards the shoreline what is the shoreline
Sophie [7]
The shoreline would be your reference point.

A reference point, in physics, is some point in space used to illustrate the location or position of other things, relative to this reference point. So in this case, the shoreline is considered as the reference point to locate the position of the surfers.

A battery of 1 V gives how much energy to each Coulomb of charge? A. Not enough info B. 5 Joules C. 1 Joule D. 0.5 Joules
Artist 52 [7]

C. 1 Joule

Explanation:

Given:

Voltage = 1V

Quantity of charge = 1coulomb

Unknown:

Energy = ?

Solution:

The amount of work done is often related to the energy in a system.

In this electrical circuit, work done is the voltage that moves a particular charge.

    work done = q x v

  q is the quantity of charge

  v is the voltage

the potential difference in circuit is the driving force of charges.

 Work done = energy = qv

inputting the parameters;

   Work done =  1 x 1 = 1J

Your clothing tends to cling together after going through the dryer. Why? Would you expect more or less clinging if all your clo
lys-0071 [83]

Answer and Explanation:

The clothing after spinning in the dryer cling together. This is because in the dryer they are rubbed against each other and due to this rubbing, electrons are transferred from one to the other clothes and acquire charge as a result of charging by friction thus producing static electricity.

As the material of the clothes in the dryer is different, clinging will be more.

The sticking of these clothes together is known as Static cling.

In case, the clothing are of same material, the static electricity produced as a result of frictional charging would be less and hence less static cling would occur.
