Question

please answer for this​

Answer 1

Answer:

My dear friend,

1. When any body with considerable volume is immersed in water, there exists an opposite force acting upwards ( known as buoyancy force), due to which weight decreases.
2. Both are a colloidal solution
3. It is v^2 = u^2 + 2as
4. velocity is m/s

Hope it helps!

Please mark as brainliest.

Answer 2

1) because of the upward buoyant force
2)bothh r colloidal
3)v^2=u^2+2as
4m/s
