Answer:
it bc the adults are bigger then us kid so when they dip in the pool it makes bigger splashes
Explanation:
Answer:
Distance will decrease and work will decrease:
F = m a Newton's Second Law
a = F / m decreasing force will decrease acceleration
S = 1/2 a t^2 = 1/2 (F / m) t^2 distance traveled will decrease as force decreases
W = F * S work will decrease as both force and distance decrease
//////Correct answer is C.///////
Answer:
Explanation:
a ) from San Antonio to Houston let distance be d km .
Average speed = total distance / total time
time = distance / speed
Total time = (d / 2 x 75 ) +( d / 2 x 106 )
= .0067 d + .0047 d
= .0114 d
Average speed = d / .0114 d = 87.72 km /h
b ) from Houston back to San Antonio
Total time = (d / 2 x 106 ) +( d / 2 x 75 )
= .0047 d + .0067 d
= .0114 d
Average speed = d / .0114 d = 87.72 km /h
c )
For entire trip :
total distance = 2d
total time = 2 x .0114 d
Average speed = 2 d / 2 x .0114 d
= 87.72 km /h .
