Answer:
0.066m
Explanation:
use the formula
velocity= frequency × wave length
344m/s = 5200Hz× wavelength
wavelength = 344m/s/5200Hz
wavelength = 0.066m(to 2 sig fig)
Heat is always transferred through the movement of matter in the convection mode of heat transmission.
<h3>What is heat transfer ?</h3>
Heat transfer is the movement of heat from one solid or liquid item to another. Always, heat moves from one body with a greater temperature to one with a lower temperature. To put it another way, heat always transfers from a hotter body to a cooler body.
- Heat energy is transferred through the mechanism of conduction when nearby atoms or molecules collide. In solids and liquids, where particles are more closely spaced, conduction happens more easily than in gases, where particles are more widely spaced.
- Here we can say that heat is transfer when there is movement between two books and hence there is change in temperature.

Answer:
Correct answer: There are four variables rather than two - The amount of charge q₁, the amount of charge q₂, the distance between the spheres and the relative dielectric permeability εr of the medium.
Explanation:
I assume you meant two spherical objects.
The force between two charged objects according to Coulomb's law is calculated by the formula:
Fc = 1/ (4 π ε₀ εr) · (q₁ · q₂) / d²
where :
- ε₀ is the dielectric permeability of the vacuum
- εr is the dielectric permeability of the medium
- q₁ the amount of charge of the first sphere
- q₂ the amount of charge of the second sphere
- d is the distance between the spheres
