Answer:
The details of bands is given in explanation.
Explanation:
The electromagnetic waves are differentiated into different bands based upon their wavelengths and frequencies. The names of different bands are as follows:
1. Radio Waves
2. Micro Waves
3. Infra-red
4. Visible light
5. Ultra Violet
6. X-rays
7. Gamma Rays
<u>The frequency of every region or rays increases from 1 through 7</u>. The <u>energy of rays also increase from 1 through 7</u>. Since, the wave length is inversely related to energy and frequency, thus the <u>wavelength of rays decrease from 1 through 7</u>.
A detailed information of the bands is provided in the picture attached.
Ans:
C
Explanation:
because it is moving down the stairs
When scientists work together it helps them achieve their goals when they share different ideas with eachother
The force of gravity between two objects is given by:

where
G is the gravitational constant
m1 and m2 are the masses of the two objects
r is their separation
In this problem, the mass of the object is

, while the Earth's mass is

. Their separation is

, therefore the gravitational force exerted on the object is
Answer:
NO
Explanation:
No, a machine cannot be 100% efficient. This is due to the movement of the moving parts siding against each other and causing friction. This friction is the one that creates heat and causes wear and tear between moving ports f the machine hence making the machine to decrease in efficiency with time
