Answer:
0.1143m
Explanation:
W=f×s
8=70s
make s the subject of the formula
s=8/70
=0.1143m
Answer:
1.1x10^-2N
Explanation:
We have the change in momentum as
P = 0.3(4.5+12)g.mph
= 0.3x0.447x(4.5+12)x10^-3
Then the force that is exerted will be
F = p/∆t
∆t = 0.2
= 0.3x0.447x(4.5+12)x10^-3/0.2
= 0.1341x16.5x10^-3/0.2
= 1.1x10^-2
Therefore the force that was exerted is equal to 1.1x10^-2
Answer:
I think B or C it won't lower so I'll go with B bc warm water is hotter than regular temp water
