A body of mass 0.5kg is thrown vertically upwards from the ground with an Initial velocity of 80.m/s
Calculate
" the potential energy at B 80.0cm above the ground​

Here's the solution,

we know,

potential energy = mgh

where,

So,

=》

=》

asking the goog might u get an answer

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
