A 500 g stone is thrown up with a velocity of 15m/s. Find its A. P. E. at its maximum height
B. K. E. when it hits the ground

hotter stars = bluer stars

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
