Answer:
the maximum height of Joe's ball will be 4 times Bill's ball.
Explanation:
let bill's velocity be v then Joe's velocity is 2v.
and initial velocities of both bill and Joe are 0
for Bill
for Joe
thus we can write that
h'=4h
the maximum height of Joe's ball will be 4 times Bill's ball.
A star is formed in a nebula for millions of years, the star then forms into a star, after so long based on its size it will turn into a supernova or a black hole. while smaller stars will turn into a supernova then into a white dwarf
Answer:
m = image distance/object distance
m=35/15=7/3
f=uv/(u+v)
35*15/(35+15)
f=10.5cm
C play all the songs on shuffle. entropy has to do with randomness
formula= W=f*d
w=work done
f=force
d=distance
w=f*d
w= 5n*0(does not budge)means does not move so distance is zero
w=5J
The work done by the children on the sumo wrestler is 5J
