A 8.6*10^ -6 C charge is places 1.00 m away from a 2.3 * 10 ^ - 4 * C charge. How large is the force of repulsion between the two charges?

Answers

Answer 1

Answer:

The force of repulsion is 17.802 N

Explanation:

Given;

magnitude of the first charge, q₁ = 8.6 x 10⁻⁶ C

magnitude of the second charge, q₂ = 2.3 x 10⁻⁴ C

distance between the two charges, r = 1 m

The force of repulsion is calculated using Coulomb's law;

[tex]F = \frac{Kq_1q_2}{r^2} \\\\F = \frac{9\times 10^9 \times 8.6\times 10^{-6} \times 2.3\times 10^{-4}}{1^2} \\\\F = 17.802 \ N[/tex]

Therefore, the force of repulsion is 17.802 N

If the distance between two objects is increased to four times the original distance.how will that increase change the force of attraction between the object

Answers

Answer:

Gravitational force becomes sixteen times lesser. The strength of the gravitational force between two objects is dependent on their mass. Gravitational force will be weaker if the objects move further away from each other.

This was used to solve for the gravitational force,

G = gravitational constant

m = mass of the first object

M = mass of the second object

d = distance between the two objects

[G * (m*M) / 16d^2] = 1/16

Two forces that make up 3rd law of motion can: 1)Act on the same object 2)do not act on same time 3)Act on different objects 4)Do not act oppositely

Answers

Answer:

3) Act on different objects

Explanation:

Newton's third law of motion states that for every action there is an equal and opposite reaction.

Action-reaction force pairs make it possible for fishes to swim, birds to fly, cars to move, etc.

Basically, action-reaction force pairs are characterized by the following statements;

I. The forces are the same type such as magnetic force, contact force or gravitational force.

II. The forces are equal in magnitude but opposite in direction.

III. They act up on two different bodies.

Hence, the two forces that make up 3rd law of motion can act on different objects.

For example, while driving down the road, a bug strikes the windshield of a vehicle (Action) and makes a quite obvious mess in front of the face of the driver of the vehicle (Reaction) i.e the bug hit the vehicle and the vehicle hits the bug.

Mike roller skates with a constant speed of 10 miles per hour. How long will he take to travel a distance of 15 miles.

Answers

Answer:

So every hour he makes 10 miles.  So he would take 1 and a half hours to go to Mcdonalds 15 miles away.

Explanation:

[tex]\huge\boxed{{\textsf{90 minutes}}}[/tex]

We know that Mike's speed is [tex]\dfrac{10\ \text{miles}}{60\ \text{minutes}}[/tex] since there are [tex]60[/tex] minutes in an hour, and we know that MIke needs to travel [tex]15[/tex] miles. We'll model this using fractions:

[tex]\dfrac{10\ \text{miles}}{60\ \text{minutes}}=\dfrac{15\ \text{miles}}{x\ \text{minutes}}[/tex]

We can see that there is a [tex]2:3[/tex] ratio here, so we'll divide the left fraction by [tex]2[/tex] and multiply it by [tex]3[/tex] to get the right fraction.

[tex]\dfrac{10}{60}\Rightarrow\dfrac{5}{30}\Rightarrow\dfrac{15\ \text{miles}}{\boxed{90\ \text{minutes}}}[/tex]

Magali exerts a force of 4.5 N to slide her Blackberry across the table (so she can hide it from Hina!). If she does 2.7 J of work in the process, how far has the Blackberry moved?

Answers

Work is equal to the magnitude of the force multiplied by the displacement x. Assuming Magali is pushing the phone, so that the force and displacement point in the same direction, then the work done is positive, and

2.7 J = (4.5 N) x   ==>   x = (2.7 J) / (4.5 N) = 0.60 m

Even if she was pulling the phone instead, the displacement would be the same, but the work done would be negative and the force would point in the opposite direction, thus also having a negative sign:

-2.7 J = (-4.5 N) x   ==>  x = 0.60 m


Two closed organ pipe gives 4 beats when sounded together at 5°C. Calculate the number of beats in 35°C​

Answers

Answer:

The number of beats is 10.58 in 35°C.

Explanation:

The beat frequency is given by : f₁-f₂

At 5°C, f₁-f₂ = 4

We need to find the number of beats in 35°C​.

The frequency in a standing wave is proportional to [tex]\sqrt T[/tex].

So,

[tex]\dfrac{f_1-f_2}{f_1'-f_2'}=\dfrac{\sqrt {T}}{\sqrt{T'}}\\\\f_1'-f_2'=(f_1-f_2)\times \dfrac{\sqrt{T'}}{\sqrt{T}}\\\\f_1'-f_2'=4\times \dfrac{\sqrt{35}}{\sqrt{5}}\\\\f_1'-f_2'=10.58[/tex]

So, the number of beats is 10.58 in 35°C.

Spaceship 1 and Spaceship 2 have equal masses of 150 kg. Spaceship 1 has an initial momentum magnitude of 900 kg-m/s. What is its initial speed?
A. 9 m/s
B. 6 m/s
C. 90 m/s
D. 60 m/s

Answers

Answer:

ans: 6 m/s

Explanation:

spaceship 1 has mass= 150kg

initial momentum of spaceship 1 = 900 kg•m/s

we know,

momentum = mass × velocity

so,

velocity = momentum/mass

= 900 / 150

= 6 m/s

since we know it was initial momentum so, velocity is initial speed,

A light wave travels through glass (n=1.50) at an angle of 35°. What angle
does it have when it passes from the glass into the air (n = 1.0)?
A. 59.4
B. 0.860
C. 22.5
D. 0.382

Answers

Answer:

A. 59.4

Explanation:

The refractive index of the glass, n₁ = 1.50

The angle of incidence of the light, θ₁ = 35°

The refractive index of air, n₂ = 1.0

Snell's law states that n₁·sin(θ₁) = n₂·sin(θ₂)

Where;

θ₂ = The angle of refraction of the light, which is the angle the light will have when it passes from the glass into the air

Therefore;

θ₂ = arcsin(n₁·sin(θ₁)/n₂)

Plugging in the values of n₁, n₂ and θ₁ gives;

θ₂ = arcsin(1.50 × sin(35°)/1.0) ≈ 59.357551° ≈ 59.4°

The angle the light will have when it passes from the glass into the air, θ₂ ≈ 59.4°.

Answers

Answer:

If the collector of the cell is covered, the voltage is higher

Explanation:

The collector of the a passive, active, or photovoltaic (PV) solar cell is the device that takes the Sun's energy by the absorption of the Sun's radiation which is then transformed into electricity and heat. The ability to absorb the Sun's energy is given by the material type and the coating of solar collector

Therefore, the device requires access to energy from Sunlight to get the energy which can be stored in a rechargeable cell and well the collector's cell is covered, access to Sunlight is denied and therefore energy is not supplied to the cells and current is not generated and there is no flow of electricity and the voltage in the circuit is lower or there is no voltage in the circuit

The statement which is wrong about the solar cell is therefore, that if the collector of the cell is covered, the voltage is higher

Surface temperature is the temperature at or near a surface. Luminosity is an absolute measure of radiated electromagnetic power (light), the radiant power emitted by a light-emitting object over time.

As it can be observed from the graph attached that Sirius have a surface temperature of about 10,000 K which can be considered as closest to 9500 K comparatively to other stars and if we see the the y coordinate of Sirius which is the luminosity representing axis , then Sirius have a value of luminosity closer to 63

(b) Determine the period of oscillation, T. Then, calculate the frequency of oscillation.

Answers

Answer:

a) A = 3 cm,  b)  T = 0.4 s,   f = 2.5 Hz,

2) A standing wave the displacement of the wave is canceled and only one oscillation remains

Explanation:

a) in an oscillatory movement the amplitude is the highest value of the signal in this case

          A = 3 cm

b) the period of oscillation is the time it takes for the wave to repeat itself in this case

          T = 0.4 s

the period is the inverse of the frequency

         f = 1 /T

         f = 1 /, 0.4

         f = 2.5 Hz

2) a traveling wave is a wave for which as time increases the displacement increases, in the case of a transverse wave the oscillation is perpendicular to the displacement and in the case of a longitudinal wave the oscillation is in the same direction of the displacement.

A standing wave occurs when a traveling wave bounces off some object and there are two waves, one that travels in one direction and the other that travels in the opposite direction. In this case, the displacement of the wave is canceled and only one oscillation remains.

What is the answer to this question?

Answers

Answer:

Explanation:

In a velocity/time (aka acceleration) graph, the slope of a line indicates the value of the acceleration in m/s/s. Acceleration is the change in velocity over the change in time. From 0 - 2 seconds, there is no change in velocity, so the acceleration during this interval is 0 (which is the same as the slope of the line). From 2 - 4 seconds, the slope of the line is -2, so the acceleration during the time interval from 2 to 4 seconds is -2 (negative because David is slowing down but is still going the same direction: to the right).
