Explain why electromagnetic forces are essential to forming compounds.

Explanation:

it's a unit used to measure charge (C)

1C=1000millicoulombs

1millicoulomb=1000microcoulumbs

Answer:

1 column - 3 x 10⁹ start columb

= 1 / 10 e mu

column is a bigger unit so in practice the smaller unit micro column is also used the smaller unit of charge

1 Milli column - 10-³

1 micro column 10-⁶

the force of attraction or illusion between the two point charge is directly proportional to the product of the magnitude and inversely proportional to the square of distance between them the direction of force along line joining the two charge

Electromagnetic radiation are a group of waves which are are produced by the vibrations of electromagnetic fields.

Electromagnetic radiation are a group of waves which are are produced by the vibrations of electromagnetic fields. Electromagnetic waves/radiation possess the ability to travel through vacuum (i.e. they do not require a material medium for their propagation) while also carrying radiant energy.

Electromagnetic fields which are the sources of electromagnetic radiation, exist as a result of the combination and interaction of travelling electric and magnetic field forces.

Electromagnetic radiations consists of the following waves: radio waves, infrared waves, visible light, ultraviolet rays, X-rays, and gamma rays.

These waves have differing and unique properties such as wavelength, frequencies, ionizing properties, penetrating ability, sources as well as well as uses. However, they have a common property of velocity- they travel with the speed of light, 3.0 * 10⁸ m/s.

In addition to having the same velocity, all electromagnetic radiation exhibit interference and diffraction.

Explanation:

|F|= B/2

B/2 = √(A²+B²+2ABcosθ) ------(1)

Since the resultant of A and B is perpendicular to Vector A

tan90°= BSinθ/(A+BCosθ)

(A+BCosθ)=0

Cosθ=-A/B ----(2)

Using equation (1)

B/2 = √(A²+B²+2ABcosθ)

B/2 = √(A²+B²+2AB×-A/B)

B/2=√(A²+B²-2A²)

B/2=√(B²-A²)

B²/4=B²-A²

A²=B²-B²/4

A²=3B²/4

A=√3B/2

Using equation (2)

Cosθ=-A/B

Answer:

Weight of the body in air = 20gf ( Wa)

Weight of the body in water = 18gf ( Ws)

Weight of the body in liquid =18.2gf ( Wl)

Now,

The loss of weight in the water = 20 - 18 or, 2 gf

So the relative density of the body is = Wa / ( wa - ws )

= 20 / 2

= 10

2) The weight loss in liquid = 20 - 18.2 or, 1.8 gf

So the relative density of the liquid is =( Wa - Wl ) / ( Wa - Ws )

= 1.8 / 2

= 0.9

The centripetal force of the rock tied to a string and swung in a circular path is determined as 1.65 N.

The angular speed of the rock is calculated as follows;

ω = 2π N

[tex]\omega = 35^0 \times \frac{2 \pi \ rad}{360^0} \times \frac{100}{3\min} \times \frac{1 \min}{60 \ s} \\\\\omega = 0.339 \ rad/s[/tex]

Answer:

D, A convex lens converges light and curves outward.

Explanation:

edge

A convex lens converges light and curves outward.

A lens that is thin at the bottom and upper edges and somewhat thick in the middle is referred to as a convex lens. The edges are not bent inside, but rather outward.

Here,

In a convex lens, the light rays travelling parallel to its principal axis are converged by it (i.e., the incident rays are directed towards the principal axis).

Since all of the light rays that are refracted by a convex lens eventually converge at a single point, where the image is created, the convex lens is also known as a converging lens.

A converging lens produced a virtual image when the object is placed in front of the focal point.

Hence,

A convex lens converges light and curves outward.
