Two square pieces of
cardboard x, y which are placed horizontally so they
are affected by atmospheric pressure, If the area of x is four times that of y, compare between the values of:
1. the atmospheric pressure on x and the atmospheric pressure on y
2. the force of the atmospheric pressure on x and that on y

i believe it is b. what was the cause of the big bang

hope this !

elctricity and magnet is conversion to it

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j

friction

explanation:

they us to move forward and backwards
