A -0.00125 C charge is placed 3.62 m from a +0.00333 C charge. What is the magnitude of the electric force between them?

Answers

Answer:

The magnitude of the force between the charges is approximately -2,858.77 N

Explanation:

The given details are;

The magnitude of the given charges;

q₁ = -0.00125 C, q₂ = +0.00333 C

The distance between the charges, r = 3.62 m

The magnitude of the electric force between the charges, 'F', between two charged particles or objects is given as follows;

[tex]F = \dfrac{k \cdot q_1 \cdot q_2}{r^2}[/tex]

Where;

k = Constant = 9 × 10⁹ N·m²/C²

q₁ = The magnitude of charge on the first charged object = -0.00125 C

q₂ = The magnitude of charge on the second charged object = +0.00333 C

r = The distance between the charges = 3.62 m

Plugging in the values, gives;

[tex]F = \dfrac{9 \times 10^9 \ \dfrac{N \cdot m^2}{C^2} \times (-0.00125 \, C) \times (+0.00333 \, C)}{\left( 3.62 \, m \right)^2} \approx -2,858.77 \, N[/tex]

The magnitude of the force between the charges, F ≈ -2,858.77 N

4. Alcohol of mass 21g and density 0.7gcm-3 is mixed with 10g of water. Determine the density
of the mixture. (density of water = 1.0g cm-3)

Answers

Answer:

The density of the mixture is 0.775 g/cm³

Explanation:

The given parameters are;

The mass of the alcohol, m₁ = 21 g

The density of the alcohol, ρ₁ = 0.7 g/cm³

The mass of the water with which the alcohol is mixed, m₂ = 10 g

The density of wate, ρ₂ = 1.0 g/cm³

The density of a substance is given by the ratio of the mass to the volume of the substance

The density of the mixture, ρ is given as follows;

[tex]\rho = \dfrac{m_1 + m_2}{\dfrac{m_1}{\rho_1} + \dfrac{m_2}{\rho_2} }[/tex]

Therefore;

[tex]\rho = \dfrac{21 + 10}{\dfrac{21}{0.7} + \dfrac{10}{1.0} } = 0.775[/tex]

The density of the mixture, ρ = 0.775 g/cm³.

What is the ratio of surface area to volume for a sphere with the following measurements?
surface are=432m^2
volume=864m^3

Answers

Answer:

S:V = 1 : 2

Explanation:

Given the following data;

Surface area, S = 432 m²

Volume, V = 864 m³

To find the ratio of surface area to volume for a sphere;

The ratio of two or more numbers are determined by reducing the numbers to their nearest minimum i.e dividing all through by the same or common number.

S:V = 432 : 864

Dividing both sides by 432, we have;

S:V = 432/432 : 864/432

S:V = 1 : 2

b. Plug in the values from this problem into the formula.


c. Solve the problem, writing out each step.


d. Correct answer

Answers

Answer:

11963.43 N

Explanation:

From the question given above, the following data were obtained:

Mass of the earth (Mₑ) = 5.97x10²⁴ Kg

Mass of satellite (Mₛ) = 1300 Kg

Radius of the earth (R) = 6378 km

Distance between the earth and satellite (r) = R + 200 Km = 6378 + 200 = 6578 Km

Force of gravity (F) =?

Next, we shall convert 6578 Km to m. This can be obtained as follow:

1 Km = 1000 m

Therefore,

6578 Km = 6578 Km × 1000 m / 1 Km

6578 Km = 6578000 m

Finally, we shall determine the force of gravity. This can be obtained as follow:

Mass of the earth (Mₑ) = 5.97x10²⁴ Kg

Mass of satellite (Mₛ) = 1300 Kg

Distance apart (r) = 6578000 m

Gravitational constant (G) = 6.67×10¯¹¹ Nm²/Kg²

Force of gravity (F) =?

F = GMₑMₛ / r²

F = (6.67×10¯¹¹ × 5.97x10²⁴ × 1300) / (6578000)²

F = 11963.43 N

Therefore, the force of gravity on the scientific satellite 11963.43 N

P = ρgh................ Equation 1

Where P = pressure, ρ = density, h = height, g = acceleration due to gravity.

From the question,

Given:  ρ = 1025 kg/m³, h = 9 m

Constant: g = 9.8 m/s²

Substitute these values into equation 1

P = (1025)(9)(9.8)

P = 90405 N/m²

Also,

P = F/A.............. Equation 2

Where, F = Force, A = Area.

Make F the subject of the equation

F = PA............... Equation 2

Given: A = 12m²

F = 12(90405)

F = 1084860 N

¿Cuál es el valor del coeficiente de roce estático entre dos superficies, sabiendo que para poner en movimiento un cuerpo de 35kg. Es necesario, vencer una fuerza de resistencia de 45 Newton?

Answers

Answer:

El coeficiente de roce estático entre las dos superficies es 0.131.

Explanation:

El coeficiente de roce estático entre dos superficies ([tex]\mu_{s}[/tex]), sin unidad, es igual a la fuerza de resistencia ([tex]F[/tex]), en newtons, dividida por el peso del cuerpo a mover ([tex]W[/tex]), en newtons.

[tex]\mu = \frac{F}{m\cdot g}[/tex] (1)

Donde:

[tex]m[/tex] - Masa, en kilogramos.

[tex]g[/tex] - Aceleración gravitacional, en metros por segundo al cuadrado.

Si sabemos que [tex]F = 45\,N[/tex], [tex]m = 35\,kg[/tex] y [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], entonces el coeficiente de roce estático es:

[tex]\mu = \frac{45\,N}{(35\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)}[/tex]

[tex]\mu = 0.131[/tex]

El coeficiente de roce estático entre las dos superficies es 0.131.

Acircuit consist of three resistor in series one of 3 ohm, one of 7 ohm , one of 10 ohm battery of emf 12volt and neglible internal resistance is connected circuit what is size of circuit supply

Answers

Answer:

0.6 A

Explanation:

Applying,

I = E/(R'+r).................... Equation 1

Where I = curent or circuit supply, R'= equivalent external resistance, r = internal resistance.

From the question,

Given: E = 12 Volt,

IF the three resistors are connected in series, R' = (3+7+10) ohm = 20 ohm,

r = neglible.

Substitute these values into equation 1

I = 12/(20)

I = 0.6 A

the acceleration of a moving vehicles is 10 metre per second square what does it means ​

Answers

Answer:

Acceleration is the rate of change of velocity. What is commonly said as ‘ten meter per second squared’ can bee broken down into ‘ten meter per second per second.’ This gives us the true meaning of the term acceleration.

Just like ‘ten meter per second’ means increasing the displacement by ten meters every second, ‘ten meter per second per second’ means increasing the velocity by ten meters per second every second.

So, basically if you consider the case of a free fall motion, where ‘t’ stands for time and ‘v’ stand for velocity at that instant:

At,

t=0, v=0 m/s

t=1, v=0+10 m/s;

t=2, v=0+10+10 m/s;

t=3, v=0+10+10+10 m/s;

This can also be thought as a Arithmetic Progression where common difference ‘D’ is the acceleration(a), since it adds a 10 m/s to velocity every second and the first term ‘A’ stands for the initial velocity (u). Using this approach we can derive to the first equation of motion:

v = u + at

Hope this Answer Helps!!

Explanation:

plz mark me as a brainlest and thank my answer

It means that the vehicle's speed increases at the rate of 10m/s every second.

At any time, it's speed is 10 m/s faster than it was 1 second earlier.

A Ferris wheel turning at a constant speed

A plane gaining speed down a runway

A runner speeding around the curve toward the finish line

A car traveling down a straight highway at constant speed

Answers

I would say the answer to your question is A Ferris wheel turning at a constant speed. The reasoning behind this answer is the fact that traveling in a constant direction at a constant speed is not accelerating. The Ferris wheel is the only option that fits this description. The last option would be incorrect due to independent causes such as speed limit changes as well as turns and stops on the highway.

A cheetah runs at a speed of 27.6 m/s. If the
cheetah runs for 9.30 s, what is the distance the
cheetah runs? Show all your work.

Answers

Answer:

256.68m

Explanation:

that is the procedure above

A cheetah runs at a speed of 27.6 m/s. If the cheetah runs for 9.30 s, then the distance covered by the cheetah would be 256.68 metes

What is speed?

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is meter/second. The generally considered unit for speed is a meter per second.

The mathematical expression for speed is given by

speed = distance /Total time

As given in the problem A cheetah runs at a speed of 27.6 m/s. If the cheetah runs for 9.30 s, we have to calculate the distance covered by the cheetah

Distance=?

speed=27.6 m/s

time= 9.30 s

speed = distance /Total time

27.6 m/s = Distance /9.30 s

Distance = 27.6×9.30

               =256.68 metes

Thus, the distance covered by the cheetah would be 256.68 metes
