<u>Answer: </u>
Balloon powered car works on the principle of Newtons III law. Escaping air from the balloon, the car accelerates forward. The reaction is the air behind the car, pushing against it, and with the same force car moves forward is the action.
<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)
3. What is the principle involved in balloon powered car?
Ans: Newtons III law.

<u>Answer</u>:
Newton proposed the "law of Universal Gravitation". He said that gravity is universal in nature and it affects all the objects. Gravity is present between you and every object having mass around you. The "Strength of the gravity" between two objects with mass is depends on the product of masses and distance between the objects.
The "Gravitational force" increases with the increase in mass of the objects and decreases with the increase in distance between the objects. The gravity exerts a force on every object. The direction of force of gravity is towards the centre of the Earth.
Answer:
Tech B
Explanation:
There is a revolution of changes occur since the beginning of vehicle creation. Many technology came into existence and proposed us the best design, features and model. But as a machine, several fatigue or wear and tear can happen to this hence a proper maintenance is required in order for smooth running of your vehicle.
Many manufacturers have booklet that mention the proper maintenance interval for better running of your vehicle. As daily environment is changing, the maintenance requirements of a vehicle is also changing. New technology is bringing new features hence their maintenance rate as well as requirement also needs to be upgraded.
