1. A swimmer has a mass of 80 kg and is swimming at a speed of 6 m/s.
a. What type of energy does she have?
b. How much energy does she have?

Explanation:

1. swimmer is having kinetic energy as it is moving with velocity of 6 meter per second..

2. Intial velocity = 6 , Final velocity = 0

Average velocity = u +v /2

6+0/2 = 6/2 = 3

So, 3 is velocity

Kinetic energy = ½ mv²

= ½× 80 × (3)²

= 40×9

= 360 Joule Answer

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
