Answer:

6.58×10⁶ F

Explanation:

Applying,

Q = CV..................... Equation 1

Where Q = charge of the capacitor, C = Capacitance of the capacitor, V = Volatage

Make C the subject of the equation

C = Q/V................. Equation 2

From the question,

Given: Q = 7.9×10⁷ C, V = 12.0 V

Susbtitute these values into equation 2

C = 7.9×10⁷/12

C = 6.58×10⁶ F

Answer:

-1m/s

Explanation:

We can calculate the speed of block A after collision

According to collision theory:

MaVa+MbVb = MaVa+MbVb (after collision)

Substitute the given values

5(3)+10(0) = 5Va+10(2)

15+0 = 5Va + 20

5Va = 15-20

5Va = -5

Va = -5/5

Va = -1m/s

Hence the velocity of ball A after collision is -1m/s

Note that the velocity of block B is zero before collision since it is stationary

Answer:

 U = 25 J

Explanation:

The energy in a set of charges is given by

          U = [tex]k \sum \frac{q_i}{r_i}[/tex]

in this case we have three charges of equal magnitude

          q = q₁ = q₂ = q₃

with the configuration of an equilateral triangle all distances are worth

          d = a

          U = k ( [tex]\frac{q_1q_2}{ r_1_2 } + \frac{q_1q_3}{r_1_3} + \frac{q_2q_3}{r_2_3}[/tex] )

we substitute

           15 = k q² (3 / a)

            k q² /a = 5

For the second configuration a load is moved to the measured point of the other two

          d₁₃ = a

The distance to charge 2 that is at the midpoint of the other two is

          d₁₂ = d₂₃ = a / 2

           U = k (\frac{q_1q_2}{ r_1_2 } + \frac{q_1q_3}{r_1_3} + \frac{q_2q_3}{r_2_3})

            U = k q² (  [tex]\frac{2}{a} + \frac{1}{a} + \frac{2}{a}[/tex] )

            U = (kq² /a) 5

substituting

            U = 5 5

            U = 25 J

Answer:

8.5 Ω

Explanation:

La resistencia de un material es directamente proporcional a su longitud e inversamente proporcional al área de la sección transversal.

La fórmula de la resistencia (R) viene dada por:

R = ρL/A

Donde ρ es la resistividad del material, L es la longitud del material y A es el área de la sección transversal del material.

Dado que:

L = 1 km = 1000 m, A = 2 mm² = 2 * 10⁻⁶ m², ρ (cobre) = 1.7 * 10⁻⁸ Ωm

Sustituyendo da:

R = 1,7 * 10⁻⁸ * 1000/2 * 10⁻⁶

R = 8.5 Ω

Answer:

The factors affecting climate are latitude, altitude, land and water distribution, distance from the sea, distance from the sun, prevailing winds and ocean currents, surface covering the land, volcanism, solar constant sunspots, wind direction and nature of mountain chains, mountain barriers.

There are six major climatic controls. They are:

Latitude: As the earth is round, sunlight does not reach everywhere equally. The temperature decreases as we move from the equator to the poles.

Altitude: As we move from the surface of the earth to the higher altitudes, the temperature decreases.

Pressure and wind system: The pressure and wind system of any area depend on the latitude and altitude of that place. Thus, it influences the temperature accordingly.

Distance from the sea: Coastal regions are cooler as compared to interior regions. As the distance from the sea increases, its influence decreases and the people experience extreme weather conditions.

Ocean currents: Cold ocean currents flowing over a region will decrease the temperature of that area whereas warm currents will increase the temperature.

Relief features: Relief features are the barriers that block currents from entering the country. High mountains act as barriers for cold or hot winds.

Answer:

327.6 is the answer but there is 2 sig figs in 14 so change it to 330

so 330 is the final answer

hope this helps

have a good day :)

Explanation:

The multiplication product of 23.4 × 14  is 327.6. However, there is only two significant figures in 14. So we have to take the answer in 2 significant figure. Hence, the product can be written as 3.3 × 10².

Significant figures are number of digits which  can be counted as certain values associated with some uncertainties as well. There are certain rules regrading the count of significant figures in a number.

The zeros after a non-decimal number cannot be taken as significant. For eg, in 4500, there are only two significant figures. The common rule for all the arithmetic operation is that, the significant figures in the product have to be equal to the number of significant figure in the number in the operation with least significant figures.

Here, the one with least significant figures is 14. It have two significant figures. Now, product of the two numbers is :

23.4 × 14 = 327.6

But the rounded product for correct significant figure is 3.3 × 10².

Answer:

   I = 2.667 kg m²

Explanation:

The moment of inertia of a body can be calculated by the expression

         I = ∫ L² dm

For high symmetry bodies the expressions of the moment of inertia are tabulated, for a rod with its axis of rotation at its midpoint it is

         I = [tex]\frac{1}{12}[/tex] m L²

let's calculate

         I = [tex]\frac{1}{12}[/tex]  2  4²

         I = 2.667 kg m²

There are approximately 6.24 x 10¹⁸ electrons contained in 1.0 C of charge. The mass of the electron in 1.0 C of charge remains the same as the mass of an electron, which is approximately 9.109 x 10⁻³¹ kg.

We may utilise the elementary charge, which represents the charge of a single electron, to calculate how many electrons are present in 1.0 C of charge. It is estimated that the elementary charge is 1.602 x 10-19 C.

Number of electrons = Charge ÷ Elementary charge

Number of electrons = 1.0 C ÷ (1.602 x 10⁻¹⁹ C)

Calculating the division:

Number of electrons ≈ 6.24 x 10¹⁸ electrons

Therefore, there are approximately 6.24 x 10¹⁸ electrons contained in 1.0 C of charge.

It is crucial to remember that the electron's mass is unaffected by the charge when considering the electron's mass in 1.0 C of charge. Regardless of the charge it carries, an electron has a mass of about 9.109 x 10⁻³¹ kg.

Thus, the mass of one electron, which is roughly 9.109 x 10⁻³¹ kg, remains constant in 1.0 C of charge.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Suppose the source is to the left of the  mirror in  question.

Parallel rays into the mirror are always reflected towards the focal point.

In the case of a concave mirror the real parallel rays pass thru the focal point.

If the mirror is convex the rays will diverge to the left and act as if they were emanating from the focal point to the right of the mirror.
