Answer:the first one was x
the second one is y
Explanation:
M=3kg
p=33kg.m/s
p=m*v
v=p/m
=33/3
=11m/s
thus option (c)
There are approximately two hundred and twenty-five point seven five calories from using 945 j of heat
A: 225.75
Answer:
The answer is B, although technically that is an eclipse.
Answer:
Explanation:
Increase in gravitational potential energy = m x g x h
where m is mass , g is gravitational acceleration and h is height
In the first case when man climbs
increase in potential = 85 x g x h = 1.85 x 10³ J
gh = 21.7647
when dog climbs
increase in potential = 14.5 x g x h J
= 14.5 x 21.7647
= 315.6 J
