Question

2. Which of the following diagram show energy transformation in a moving LRT?
a Chemical energy ➡ mechanical energy
b. electrical energy➡mechanical energy
c electrical energy➡light energy
d. Light energy➡sound energy
​

Answer 1

Answer:

electrical energy➡mechanical energy

Explanation:

electrical energy➡mechanical energy

Answer 2

The option which shows energy transformation in a moving LRT is:

c.electrical energy ➡ light energy

• Light rail transit or LRT's are some of the most common means of public transport.
• They are given energy through power lines and that energy is converted by a motor to mechanical energy.
• They often travel at lower speed than regular trains and are used for in city transport mainly so as to not cause further energy loss so as to maintain higher speeds.
• Certain amount of electrical energy gets dissipated as heat and sound as well.
• Thus, the energy transformation in a moving LRT is electrical energy to mechanical energy.
