Answer: It will remain the same

Explanation:

According to <u>Coulomb's Law:</u>    

<em>"The electrostatic force F_{E} between two point charges q_{1} and q_{2} is proportional to the product of the charges and inversely proportional to the square of the distance d that separates them, and has the direction of the line that joins them".  </em>

<em />

Mathematically this law is written as:  

F_{E}=K\frac{q_{1}.q_{2}}{d^{2}} (1)

Where:  

F_{E}  is the electrostatic force  

K is the Coulomb's constant  

q_{1}=q_{2}=q are the electric charges , which in this case have the same positive charge

d is the separation distance between the charges

Rewritting we have:

F_{E}=K\frac{q^{2}}{d^{2}}    (2)

Now, if the first charge is doubled:

q_{1}=2q_

And the second is reduced to a half:

q_{2}=\frac{1}{2}q

We will have the following:

F_{E}=K\frac{(2q)(\frac{1}{2}q)}{d^{2}} (3)

F_{E}=K\frac{q^{2}}{d^{2}} (4)

As we can see equation (4) is equal to equation (2), this means the force of repulsion between both charges will remain the same

An inventor develops a stationary cycling device by which an individual, while pedaling, can convert all of the energy expended
mr Goodwill [35]

Answer:

Q=94185\ J

Explanation:

Given:

  • mass of water, m=0.3\ kg
  • initial temperature of water, T_i=20^{\circ}C
  • final temperature of water, T_f=95^{\circ}C
  • specific heat of water, c=4186\ J.kg^{-1}.K^{-1}

<u>Now the amount of heat energy required:</u>

Q=m.c.\Delta T

Q=0.3\times 4186\times (95-20)

Q=94185\ J

Since all of the mechanical energy is being converted into heat, therefore the same amount of mechanical energy is required.

A child is sliding down a slide at the playgound. is mechanicalenergy conserved
Flauer [41]

No. Mechanical energy is not conserved.  There's quite a bit of friction on the slide.  So some of the potential energy is lost to heat on the way down, and the child arrives at the bottom with hot pants and less kinetic energy than you might expect.

What happens to light waves from a star as the star moves toward Earth?
Musya8 [376]
This shifts the star’s spectral lines toward the blue end of the spectrum. If the star is moving away from us, it’s waves are effectively stretched out when they reach earth, increasing their wavelength. This shifts the star’s spectral lines toward the red end of the spectrum.
