Question

Match the following. a. Pendulum - Depends on time b. Lifting object - Roller coaster c. Work - Depends on speed d. Bow and arrow arrangement - Energy e. Power - Compressed spring​

Answer 1

Answer:

It depends on time of pendulum.

Answer 2

Correct Matching rows are,

• Pendulum                      -                        Depends on the speed

• Lifting object                 -                        Roller Coaster
• Work                               -                        Energy
• Bow and Arrow             -                        Compressed spring

        management      

• Power                             -                        Depends on the time

The Pendulum depends on speed as it is indirectly proportional to it.

The Lifting of objects is similar to a roller coaster as they both reach some definite height and return back.

The Work and Energy both are same, we can relate it with their formulas.

The Bow and Arrow management work the same as the compressed springs decompresses with a sudden movement.

The Power depends on time as it is the rate of doing work.
