Answer:
Mass doesn't change.
Weight is measured based on gravitational pull.
Explanation:
The value of the equivalent resistance for the three resistors connected in series will be the sum of the three values.
To find the answer, we have to know more about the equivalent resistance.
<h3>
What is meant by equivalent resistance?</h3>
- equivalent resistance is the total value of the resistance connected in a circuit.
- If n resistors are connected in series, then the equivalent resistance will be,

- In our question we have three resistors. Thus, the equivalent resistance will be,

Thus, we can conclude that, the value of the equivalent resistance for the three resistors connected in series will be the sum of the three values.

Answer:
Yes convection will always work faster and more efficiently.
Explanation:
When a gas or a liquid is heated, hot areas of the material flow and mix with the cool areas. ... Convection transfers heat over a distance faster than conduction. But ultimately conduction must transfer the heat from the gas to the other object, though molecular contact.
