The correct answer is 1.2 m/s
: mv+mv=mv+mv
(0.5kg)(2m/s)+(0.4kg)(0m/s)=(0.5kg)v+(0.4kg)(1m/s)
= 1kg*m/s=(0.5kg)v+0.4kg*m/s
=1kg*m/s-0.4kg*m/s=(0.5kg)v
=0.6kg*m/s=(0.5kg)v
to solve for v we divide both side by 0.5kg
v=1.2m/s

Answer:
The gravity is pulling the diver downwards but the rotation of the body means gravity cant pull him down as quickly

Answer:
Explanation:
Given
Electrostatic force between two electrons is equal to weight of one electron
i.e.

where
are the charge of particles
mass of electron
r=distance between them

It means every thing is made out of Atoms and some things are element componds so elements are the "backbone" of the compounds.
