Answer:
The distance between the charges is 9.5 cm
(c) is correct option
Explanation:
Given that,
Charge 
Force F = 1 N
We need to calculate the distance between the charges
Using Coulomb's formula

Where, q = charge
r = distance
F = force
Put the value into the formula




Hence, The distance between the charges is 9.5 cm

Answer:
Infrared photons carry lower radiation energy than the visible light.
Explanation:
- Each photon carries an energy that is directly proportional to its frequency, being this proportionality constant the Planck's constant h.
- So, we can write the energy of a single photon as follows:

- Since there exists an inverse relationship between wavelength and frequency, and infrared radiation has longer wavelengths, this means that its frequency is lower than the one of the visible light.
- So, an infrared photon carries less energy that one of the visible light.
Answer:
Electrical Energy
Explanation:
An electric generator is a device that changes kinetic energy to electrical energy through electromagnetic induction. Electromagnetic induction is the process of generating electric current with a magnetic field. ... Because the coil is rotating in a magnetic field, electric current is generated in the wire.
