The work done is positive and is equal to 20000 J

<h3>What is work done?</h3>

Work done is defined as the product of force and the distance moved by the force.

Mathematically:

  • Work done = force * distance

The work done by the force = 20 * 1000 = 20000J

The work done is positive and is equal to 20000 J

Which of the following can only be a situation of increasing temperature?
Papessa [141]

Increasing the temperature causes an increase in the average kinetic energy of the particles of a material.

<h3>What is average kinetic energy of particles?</h3>

The average kinetic energy of particles is the energy possessed by particles due to their constant motion.

The constant motion of particles occurs due to the energy acquired by the particles, when the temperature of the particles increases, the average kinetic energy increases which in turn increases the speed of the particles.

Thus, we can conclude that, increasing the temperature causes an increase in the average kinetic energy of the particles of a material.

Which statement is true for a series circuit?
Anni [7]

Each of those choices has some truth to it, but three of the five choices also include some nonsense.

A.  The voltage <em>divides proportionally</em> among all resistors in the circuit.

<em>B.  </em> As more resistors are added, the current will decrease.   <em>True,</em> because the total resistance will increase.

C.   The <em>sum </em>of the voltage drops will be the total voltage in the circuit.

D.   The current is the same <em>through</em> all resistors in the circuit.

<em>E. </em>  The equivalent resistance will be greater than the individual resistors.  <em>True,</em> because the equivalent resistance is the sum of the individual resistors.
