The correct answer is option B. i.e. 60 ohm.
The diagram is attached.
Since all the resistances are attached in series.
Hence, the total resistance will be the sum of all resistances.
R_total = R_1+R_2+ R_3
= 10+20+30
= 60 ohms.
Therefore, option c is correct answer.
Answer:
Work = Mass * Gravity * Height and is measured in Joules. Imagine you find a 2 -Kg book on the floor and lift it 0.75 meters and put it on a table. Remember, that “force” is simply a push or a pull. If you lift 100 kg of mass 1-meter, you will have done 980 Joules of work.
Explanation:
B. The sound of the engine will get louder and the pitch higher.
