Answer:

[tex]F_c = \frac{KQ_1Q_2}{R^2}[/tex]

Explanation:

Coulomb’s law is given as;

[tex]F_c = \frac{KQ_1Q_2}{R^2}[/tex]

where;

F is the electric force between q₁ and q₂

k is the coulomb’s constant  = 9 x 10⁹ Nm²/C²

r is the distance between the two charges

q₁ and q₂ are the two charges

Therefore, the coulomb’s law is given as [tex]F_c = \frac{KQ_1Q_2}{R^2}[/tex]

Let's say the force of gravity betwen you and the Earth (your "weight") is 100 pounds.

Then the force of gravity between you and a 10-pound bowling ball (sitting on the table 3-ft away from you) is about 0.000 000 049 of an ounce !

It's there, but it's too small for you to feel.

And it's not strong enough for the pencil or the bowling ball to jump up off the table, fly through the air, and stick to you.

Answer:

The unit of speed is m/s.

Answer:

[tex] Power = \frac {mgh}{time} [/tex]

Explanation:

2. Power can be defined as the energy required to do work per unit time.

Mathematically, it is given by the formula;

[tex] Power = \frac {Energy}{time} [/tex]

3. Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

[tex] P.E = mgh[/tex]

Where,

P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

4. Substituting the equation in 3 into equation in 2 above, we have;

[tex] Power = \frac {mgh}{time} [/tex]

Answer:

1. answer - it is conserved in a system

2. answe- impulse is equal to the change in momentum

Answer:

before this type of attack, high acceleration is the most important thing.

Explanation:

As the zebra is ambushed by the crocodile the most important thing is a quick reaction, in this attack the most likely is that the crocodile is in the water so it cannot run after the zebra.

Consequently, before this type of attack, high acceleration is the most important thing.

Saturn is a planet in solar system. It's ring is made out of small covered ice particle. It has over 30 moons.

Answer:

a. 4.99 × 10⁻⁴ N b. 1.46 × 10⁻³ N c. 4.83 nC

Explanation:

(a) Find the magnitude of the electric force acting on each ball.

The tension in the string, T is resolved into horizontal and vertical components Tsin20° and Tcos20° respectively, since the string makes an angle of 20° with the vertical.

Let F = electric force and W = mg be the weight of the ball where m = mass of ball = 0.14 g = 0.14 × 10⁻³ kg and g = acceleration due to gravity = 9.8 m/s²

The electric force acts in the opposite direction to the horizontal component of the tension in each string. Since the masses are in equilibrium,

Tsin20° = F (1)

Also, the weight of the ball acts downwards, opposite to the direction of the vertical component of the tension in the string. Since the masses are in equilibrium,

Tcos20° = W = mg

Tcos20° = mg (2)

Dividing (1) by (2), we have

Tsin20°/Tcos20° = F/mg

tan20° = F/mg

F = mgtan20°

So, F = 0.14 × 10⁻³ kg × 9.8 m/s²× tan20°

F = 0.4994 × 10⁻³ N

F = 4.994 × 10⁻⁴ N

F ≅ 4.99 × 10⁻⁴ N

(b) Find the tension in each of the threads.

Since  Tsin20° = F

T = F/sin20°

=  4.99 × 10⁻⁴ N/sin20°

= 4.99 × 10⁻⁴ N/0.3420

= 14.59 × 10⁻⁴ N

= 1.459 × 10⁻³ N

≅ 1.46 × 10⁻³ N

(c) Find the magnitude of the charge on the balls.

From Coulomb's law, the electric force between the masses of charge q and separated by a distance r = 2.05 cm = 2.05 × 10⁻² m

F = kq²/r² where k = 9.0 × 10⁹ Nm²/C²

q² = Fr²/k

q = √(Fr²/k)

q = [√(F/k)]r

Thus,  

q = [√(F/k)]r

q = [√( 4.99 × 10⁻⁴ N/9.0 × 10⁹ Nm²/C²)]2.05 × 10⁻² m

q = [√(0.5544 × 10⁻¹³ C²/m²)]2.05 × 10⁻² m

q = [√(5.544 × 10⁻¹⁴ C²/m²)]2.05 × 10⁻² m

q = [2.355 × 10⁻⁷ C/m]2.05 × 10⁻² m

q = 4.83 × 10⁻⁹ C

q = 4.83 nC

Explanation:

One reason that electromagnetic waves are used in long-distance communication is, that they do not lose energy over long distances. So Option C   is correct

Electromagnetic waves are a type of wave that consists of oscillating electric and magnetic fields. They are propagated through space or through a material medium, and they have the ability to travel through a vacuum, which is the absence of matter. Electromagnetic waves have a wide range of frequencies, which determines the type of electromagnetic wave. The most familiar types of electromagnetic waves include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

One of the property of the electromagnetic waves is that they do not lose energy over long distances.

Answer:

400 N

Explanation:

From the question,

F = kmm'/r²........................ Equation 1

Where F = gravitation force, m and m' = mass 1 and mass 2 respectively, r = distance between the masses.

Given; F = 800 N

Substitute these values into equation 1

800 = kmm'/r².............. Equation 2

If the distance is doubled (2r), and one of the mass is doubled (2m), The new force is

F' = k(2m)(m')/(2r)²

F' = 2kmm'/4r²

F' = kmm'/2r²................. Equation 3

Comparing equation 2 and equation 3

F' = F/2............................ Equation 4

Substitute the value of F into equation 4

F' = 800/2

F' = 400 N

Answer:

C.cathode, cathode

Explanation:

In electrolysis, a device called ELECTRODE, which electric current passes through is used. However, electrodes can either be anode or cathode depending on the charge. Anode is a positive electrode that attracts negative ions while cathode is a negative electrode that attracts positive ions.

According to this question, Copper (Cu) and hydrogen (H) which are both positive ions i.e. Cu2+ and H+ will move towards and form at the CATHODE. Hence, the answer is cathode, cathode for the respective element.

Answer:

so if it's 20 you should put 20 times 10 15 * 30 and 1.3 * 5 mg and if you put that milligrams in there it'll solve the destination I saw the white way you going so yeah just be careful at least you want to make the milligrams even a multimacy with the y i and replace it with the 14a

Answer:

D

Explanation:

speed = frequency x wavelength

speed of light in vacuum is 3.0 x 10^8

wavelength = 5.32 x10 ^-7

3.0 x 10 ^ 8 = 5.32 x 10^-7 x frequency

frequency = 5.63909 x 10^14

round it off = 5.64 x 10^14 Hz

thus the answer is D

Answer:

When covalent compounds dissolve in water, they break apart into molecules, but not individual atoms. Water is a polar solvent, but covalent compounds are usually nonpolar. This means covalent compounds typically don't dissolve in water, instead, it makes a separate layer on the water's surface.
