A charged particle of 5.1 nC and another with 2.6 nC are separated by a distance of 5.5 m. What is the electric potential energy between the particles?

Answers

Answer:

The electric potential energy between the particles is 2.167 x 10⁻J

Explanation:

Given;

a charged particle, q₁ = 5.1 nC

another charged particle, q₂ = 2.6 nC

distance between the charged particle, r = 5.5 m

The electric potential energy between the charged particles is calculated as;

[tex]U_E = \frac{kq_1q_2}{r}[/tex]

where;

[tex]U_E[/tex] is the electric potential energy between the particles

k is coulomb's constant = 8.99 x 10⁹ Nm²/c²

Substitute the given values and solve for electric potential energy;

[tex]U_E = \frac{kq_1q_2}{r} = \frac{8.99*10^{9}*5.1*10^{-9}*2.6*10^{-9}}{5.5} \\\\U_E = 2.167 *10^{-8} \ J[/tex]

Therefore, the electric potential energy between the particles is 2.167 x 10⁻J

What is the critical angle for glass when the refractive index is 1.45

Answers

Answer:43.6°

Explanation:

Refractive index=n=1.45

Critical angle=c

n=1/sinc

1.45=1/sinc

Cross multiply

1.45sinc=1

Divide both sides by 1.45

(1.45sinc)/1.45=1/1.45

sinc=0.6897

c=sin(inverse)(0.6897)

c=43.6°

Critical angle is 43.6°

Answers

Answer:

0.25 Hz

4 s

Explanation:

Speed = wavelength × frequency

7 m/s = 28 m × f

f = 0.25 Hz

Frequency = 1 / period

0.25 Hz = 1 / T

T = 4 s

Rohit placed a pencil perpendicular to principal axis in front of a converging
mirror of focal length 30 cm. The image formed is twice the size of the pencil.
Calculate the distance of the object from the mirror.

Answers

Answer:

45 cm ( in my opinion)‍♀️

Explanation:

( Using the mirror formula)

1/ u + 1/v = 1/f

( introducing magnification; m into the formula )

u( 1/u  + 1/v ) =u×1/f

1 + u/v =u/f

( But u/v =1 ÷v/u= 1/m)

1 +1/m =u/f

(Supposing m is actually equal to 2, and f =30 cm, then;)

1 + 1/2 =u/30

2+1= u/15

3=u/15

3×15=u

45 cm=u

A. Electricity will flow if the atoms in the material are bound tightly to each other.

B. Electricity will flow if the atoms in the material are bound loosely to each other.

C. Electricity will flow if the electrons are bound tightly to their atoms in the material.

D. Electricity will flow if the electrons are bound loosely to their atoms in the material.

Answers

Answer:

D. Electricity will flow if the electrons are bound loosely to their atoms in the material.

Explanation:

The continuous flow of charges is known as electricity (current). The flow of these charges are due to free or mobile electron within the atoms of the conductors. The materials which will allow current to pass through them, must have free or mobile electrons which are loosely bound to their atoms.

Thus, the correction for this question is "D"

D. Electricity will flow if the electrons are bound loosely to their atoms in the material.

Each gas sample has the same temperature and pressure. which sample occupies the greatest volume? each gas sample has the same temperature and pressure. which sample occupies the greatest volume? 40.0 gar 20.0 gne 20.0 gh2 4.0 ghe

Answers

Answer:

20 gram of H as the greastest volume

Explanation:

Each gas sample has the same temperature and pressure. which sample occupies the greatest volume? each gas sample has the same temperature and pressure. which sample occupies the greatest volume? 40.0 gar 20.0 gne 20.0 gh2 4.0 ghe

Given that,

40.0 g of Ar

20.0 g of Ne

20.0 g of h

24.0 g of he

The ideal gas equation ; Pv = nRT

where P is the pressure, V is the volume, R is the gas constant, T is the temperature, n is the number of mole

which is equal to

n = m / M

where m is the given mass

M is the molar mass

The given gas sample are at the same temperature and pressure,

So, the temperature, pressure and gas constant are fixed.

Therefore the volume is proportional to the given mass and molar mass

V ∝ m/M

Substitute the given mass and molar mass of given masses for comparison

No of mole of Ar = mass / molar mass

= 40 / 40 = 1 mole

No of mole of Ne = mass / molar mass

= 20 / 20 = 1 mole

No of mole of h = mass / molar mass

= 20 / 1 = 20 mole

No of mole of he = mass / molar mass

= 24 / 4 = 6 mole

Hence, 20 gram of H as the greastest volume

A sphere of radius 10.0cm is moulded into a uniform cylindrical wire of same radius r calculate length in millimeters​

Answers

Answer:

133.33 mm

Explanation:

First we need to find the volume of the sphere. The volume of a sphere is given by:

V = (4/3) * pi * r^3

With a radius of 10 cm, we have:

V = (4/3) * pi * r^3 = 4188.79 cm3

The sphere will be moulded into a cylinder, so the volume will be the same. The volume of a cylinder is:

V = pi * r^2 * h

Where h is the height of the cylinder, and for this case, it will be the length.

The radius is the same old radius, so we have:

4188.79 = pi * 10^2 * h

h = 4188.79 / 100pi = 13.3333 cm

In millimeters, we have h = 133.33 mm

Diffraction of white light with a single slit produces bright lines of different colors.What is the color of the central image?

Answers

Answer:

white

Explanation:

This experiment causes lines of different colors because the constructive interference depends on the wavelength, so for different wavelength, the position of the maximum will be different.

Now, in diffraction fo a single slit we always have a central maximum (for all the colors)

This means that after the diffraction, we will have that all the colors have a maximum in the center, which will produce white light again, then the color of the central image is white

Um joalheiro recebe uma encomenda onde ele deve fazer alguns anéis de prata. Ele dispõe de um pedaço de 100 g de prata mas precisa derrete-lo para colocar a prata em moldes específicos e construir esses anéis. O principal problema desse procedimento é que a temperatura de fusão da prata é muito alta e requer condições especiais. A prata possui temperatura de fusão de 961 ºC, calor latente de fusão de 21 cal/g e calor específico no estado sólido igual a 0,056 cal/gºC. Determine a quantidade de calor aproximada para fundir as 100 g de prata sabendo que sua temperatura inicial é de 20°C. A 2,1 kcal B 0,5 kcal C 7,4 kcal D 5,3 kcal E 6,3 kcal

Answers

Answer:

Correct option: C -> 7.4 kcal

Explanation:

First we need to find the energy necessary to heat the silver from 20°C to 961°. The change in temperature is 961 - 20 = 941, so the energy necessary is:

941 * 0.056 * 100 = 5269.6 cal

Then, for the melting process, we will need:

21 * 100 = 2100 cal

So the total energy needed is:

5269.6 + 2100 = 7369.6 cal = 7.4 kcal

Correct option: C

What is law of energy conservation?

Energy can neither be created nor be destroyed , it gets only transferred from one form to another.

What is photosynthesis?The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.In simple words by the process of photosynthesis a tree makes food for itself.

What happens when a tree grows?Tree makes food by absorbing the sunlight.The energy of the sunlight is used in making of ATPs in trees.ATP ( Adenosine triphosphate ) is used in various operations in trees.So, the sunlight is light energy which get converted into ATPs , which is chemical energy.

A force of 1000 Newtons is used to push a box on a flat floor. It accelerated at a rate of 5 m/s2. What is the mass of the wagon?

Answers

Answer:

67.56kg

Explanation:

Fapp+mg = ma

Fapp= applied force

mg = reactional force

g = acceleration due to gravity

Where g = 9.8m/s^2 a= 5 m/s2, Fapp= 1000N.

1000N = ma + mg

1000N = m( a+g )

1000N = m ( 5+9.8)

1000N = m×14.8

m = 1000÷14.8

m = 67.56kg.

Hence the mass of the wagon will be 67.56kg
