vivado [14]
The correct answer to this question is this one:

By definition, if a molecule is composed of two hydrogen atoms and one oxygen atom, that molecule is a water.<span> In fact, the structure of water is written as H20, which signifies that two hydrogen (H) atoms and one oxygen (O) atom make up the molecule.</span>

In order for an external force to do work on a system, Question 9 options: a) there must be a component of the force perpendicul
zepelin [54]

Answer:

b) there must be a component of force parallel to the motion of the object.

Explanation:

We know that work done on a body by an external force is calculated by the formula given below:

W = F.d = Fd Cos θ

where,

W = Work Done by the force on the body

F = Magnitude of force

d = displacement of the body

θ = The angle between the direction of motion of the body and the force applied

It is clear from the formula of the work done, that "F Cosθ" represents the component of the force, that is acting in the direction of motion of the object or parallel to the direction of motion of the object. So, if there is no component of force parallel to motion of object, then this factor will become zero. As a result, the work done will also be zero.

Therefore, the correct option will be:

b) <u>there must be a component of force parallel to the motion of object.</u>

Electromagnetic radiation is more common than you think. Radio and TV stations emit radio waves when they broadcast their progra
meriva

Answer:

1) i. All these technologies use radio waves, including high-frequency microwaves.

ii. Microwave ovens emit in the same frequency band as some wireless Internet devices.

2. B. The earth absorbs visible light and emits radiation with a longer wavelength.

Explanation:

Electromagnetic radiations are generated when there is an interference between electric and magnetic fields traveling at right angles to each other. All electromagnetic waves forms a spectrum with respect to their frequency and wavelength. The higher the wavelength, the lower the frequency.

All these waves move with the same and constant speed, but are generated from different sources. From the given applications, X-ray has a high frequency, but low wavelength.

In the second case, infrared waves have longer wavelength than visible light.
