Answer:

Opposite sides of a parallelogram are parallel and equal. In a rectangle, the opposite sides are parallel and equal. Also, all the interior angles of the rectangle are of the same measure, i.e., (90o). In other words, a parallelogram with each angle a right angle becomes a rectangle. Therefore, a rectangle can be thought of as a special parallelogram.

Step-by-step explanation:

Answer:

Expansion:

• Expansion is the process in which volume of the system is gradually increases.
• In Expansion pressure and temperature in the object decreases and heat transfer may or may not be possible.

• Examples:

1. Expansion of metal after heating,
2. Expansion of the balloon when we fill air in it.

Compression:

• Compression is a process under which volume of the system is gradually reduced.
• While compression, pressure and temperature in the object increases where heat transfer may or may not be possible.

• Examples:

1. Compression of metal after heating,
2. Compression of the balloon when we release air in it.

Answer:

The dual nature of light means that, in some experiments, light behaves as a wave. In other experiments, light behaves as a particle. In 1801, Thomas Young shined light between two adjacent slits.

Answer:

The nature of light is twofold. It can act as a particle (a photon) at times, which explains why light travels in straight lines. It can function like a wave at times, explaining how light bends (or diffracts) around an object. Scientists embrace the evidence that supports the dual nature of light (despite the fact that it defies our common sense!). Light is assumed to be made up of photons, which are tiny amounts of energy that behave like particles. The way light travels in straight lines or reflects off mirrors is explained by particles.
