Question

why do girls have period​

Answer 1

Step-by-step explanation:

Given:-

Mass of body ,m = 10Kg

Velocity ,v = 5m/s

To Find:-

Kinetic Energy ,KE

Solution:-

As we know that the energy possess by body due to its motion is called Kinetic Energy.

• KE = 1/2mv²

Where,

KE is the Kinetic Energy

m is the mass

v is the speed/velocity

Substitute the value we get

→ KE = 1/2×10×5²

→ KE = 1/2× 10×25

→ KE = 250/2

→ KE = 125 J

Therefore, the kinetic energy of the body is 125 Joules..

Hence, Option (b) 125 J is the correct answer .

Answer 2

Answer:

A period happens because of changes in hormones in the body. Hormones give messages to the body. These hormones cause the lining of the uterus (or womb) to build up. This gets the uterus ready for an egg (from the mom) and sperm (from the dad) to attach and grow into a baby.
