Summer Home Assignment Physics

The document contains a series of physics questions covering topics such as forces, pressure, buoyancy, light behavior, and electric power. It asks for differentiation between balance and unbalance forces, the relationship between pressure, force, and area, the behavior of balloons at different altitudes, and the principles of reflection and refraction. Additionally, it includes calculations related to electric power and the physics behind the floating of steel ships despite their density.

Physics

1. Differentiate between Balance and unbalance forces with supporting examples from real world?

2. How pressure is related to force and area? Assuming same forces is applied at both ends of the thumb-pin, on which

side is greater pressure and why?

3. If the balloon is filled on earth from air and carried to mountain, why it expands?

4. Steel is almost eight times denser than water. Yet huge steel ships don’t sink. If the steel is denser than water, how

can these ships floats?

5. If black is not a color of the visible light, why some object still looks black?

6. Why the light bend when it enters from one medium to another medium? When its bend away and towards the

normal?

7. Make a chart showing difference between reflection and refraction of light with daily life examples.
