Answer:

1.) Radar

2.) Cancer Treatment

4.) Cooking

Explanation:

Microwaves are a type of electromagnetic radiations, like radio waves, X-rays, Gamma Rays, ultraviolet radiation. Microwaves has a wide range of applications. It has frequency range 1GHz to 300GHz and has smaller wavelengths. As microwaves do not bend by any obstacles coming in their path, So, it can be used in radar. In cancer treatment, it is used to increase the temperature of tumor cells by high-power microwaves, results in turns cell membrane damage, which in results destruction of cancer cells. In cooking, microwave heat food like the sun rays your face i.e by means of radiation. It increases the energy of molecules inside food, which results in cooking or heating the food.

Answer:

0 Joules

Explanation:

The work done is given by

W=F\times s\times cos\theta

where,

F = Force applied

s = Displacement of the object = 0 m

\theta = Angle between the force applied and the horizontal = 0

W=F\times 0\times cos0\\\Rightarrow W=0\ J

Work is only observed when there is a displacement.

The work done by me is 0 Joules as I was unable to move it.

Which of these best explains why people on Earth cannot see the entire shape of the Milky Way
BartSMP [9]
I believe the answer is A.

Since the Earth is in the Milky Way and not outside it, we cannot see the exact shape of it. Physicists have been able to track and graph the movements of the planets accurately for thousands of years, but that does not mean we know the shape of the entire solar system.<span />
