Answer:
Explanation:
Work done in carrying bricks
mgh
= 207 x 9.8 x 3.65
-= 7404.4 J
Work done in compressing gas
PΔV
Pressure x change in volume
1.8 x 10⁶ ΔV = 7404.4
ΔV = 7404.4 / 1.8 x 10⁶m³
= 4113.33 x 10⁻⁶ m³
= 4113.33 cc
Answer:
Explanation:
Recall that in this case, friction is not taken into account. Thus, Using the free body diagram, according to Newton's second law, we have:
For the lighter block:
For the heavier block:
The acceleration is the same for both blocks:
So, replacing (2) in (1):
Dip. It means there is a dip in the road up ahead. Hope this helped! <3
