Answer:
![U=50.96J](https://tex.z-dn.net/?f=U%3D50.96J)
Explanation:
The electrostatic potential energy for pair of charge is given by
U=1/4π∈₀×(q₁q₂/r)
Hence for a system of three charges the electrostatic potential energy can be found by adding up the potential energy for all possible pairs or charges.For three equal charges on the corners of an equilateral triangle,the electrostatic potential energy is given by:
U=1/4π∈₀×(q²/r)+1/4π∈₀×(q²/r)+1/4π∈₀×(q²/r)
U=3×1/4π∈₀×(q²/r)
Substitute given values
So
B b b b b b b bb bb bb b b b b b b b b b
Answer:
Earth's tilted axis
Explanation:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays.
Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy.
If the temperature is increased the particles gain more kinetic energy or vibrate faster. This means that they move faster and take more space.
