<em>Some scientific questions are:</em>
1. What is the energy stored in the balloon?
Ans: Potential energy (Potential energy is stored in elastic balloon)
2. Which energy is used in balloon-powered car?
Ans: Kinetic energy. (Whenever the balloon escapes the air, potential energy is converted into Kinetic energy)

Explanation:
Answer:
1. 150C.
2. 50sec
3.1.5a
Explanation:
1. I = Q/T
Q= 30x5
=150c
2.applying the formulae, I = Q/T
T= Q/I
=500/10
=50sec.
3. using the formulae i=q/t
i= 120/80
=1.5a.
