Answer:
The volume of the balloon increases in the upper atmosphere.
Explanation:
p1= 1 atm
p2= 0.15 atm
V1= 15.6 L
V2= ?
p1*V1= p2 * V2
V2= (p1/p2)*V1
V2= 104 L
Answer:
150 m
Explanation:
Given,
u=5m/s
a=2m/s2
t=10s
v=?
s=?
Now,
v=u+at
=5+2×10
=5+20
=25m/s
So,
s=u+v/2×t
=5+25/2×10
=30/2×10
=15×10
=150m
Solution:
54 / 9 = 6 boxes.
