HELPPP WILL GIVE BRAINLIEST!!!!
marishachu [46]

Explanation:

Thermal energy is basically the energy derived from heat when there is a temperature change in a body.

Kinetic energy is the energy due to the motion of a body.

Potential energy is the energy at rest or due to the position of a body.

  • Thermal energy is highly related to kinetic and potential energy.
  • Thermal energy is a type of kinetic energy because it causes the motion of the particles in a body.
  • An increase in thermal energy gives the particles more energy to move and then, their kinetic energy increases.
  • Kinetic energy is directly related to thermal energy.
  • A low thermal energy increases the potential energy in a body.
  • A body at rest will exert its maximum potential energy.

Calculate the total resistance for a 650ohm , a 350 ohm , and a 1000 ohm resistor connected in series
Mekhanik [1.2K]

Answer:

2000 ohms

Explanation:

Resisters in series just add.

Rt = R1 + R2 + R3

R1 = 650 ohm

R2 = 350 ohm

R3 = 1000 ohm

Rt = 650 + 350 + 1000

Rt = 2000 ohms.
