Answer:

F = 3.86 x 10⁻⁶ N

Explanation:

First, we will find the distance between the two particles:

[tex]r = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2+(z_{2}-z_{1})^2}\\[/tex]

where,

r = distance between the particles = ?

(x₁, y₁, z₁) = (2, 5, 1)

(x₂, y₂, z₂) = (3, 2, 3)

Therefore,

[tex]r = \sqrt{(3-2)^2+(2-5)^2+(3-1)^2}\\r = 3.741\ m\\[/tex]

Now, we will calculate the magnitude of the force between the charges by using Coulomb's Law:

[tex]F = \frac{kq_{1}q_{2}}{r^2}\\[/tex]

where,

F = magnitude of force = ?

k = Coulomb's Constant = 9 x 10⁹ Nm²/C²

q₁ = magnitude of first charge = 2 x 10⁻⁸ C

q₂ = magnitude of second charge = 3 x 10⁻⁷ C

r = distance between the charges = 3.741 m

Therefore,

[tex]F = \frac{(9\ x\ 10^9\ Nm^2/C^2)(2\ x\ 10^{-8}\ C)(3\ x\ 10^{-7}\ C)}{(3.741\ m)^2}\\[/tex]

F = 3.86 x 10⁻⁶ N

Answer:

The coils are not electrically connected. ... the primary coil current produces a magnetic field, which changes as the current changes. the iron core increases the strength of the magnetic field. the changing magnetic field induces a changing potential difference (voltage) in the secondary coil.

There is a voltage between the two terminals of the secondary coil because the magnetic field/magnetic flux is strengthened by the iron core. The secondary coil's potential difference (voltage) changes as the magnetic field changes. Energy is transferred by law of conversation .

Magnetic flux is the number of magnetic field lines passing through a closed surface.

There is a change in magnetic flux associated with a coil it gives rise to an induced current and hence an induced EMF in the coil. This phenomenon is called electromagnetic induction.

Law of conservation of energy states that energy can neither be created nor be destroyed . It can only be converted from one form to another form.

Answer:

True

Explanation:

This is true because in an energy flow, the primary producers such as plants produce their own foods by using energy from the sun. These primary producers are consumed by primary consumers such as rabbits for food, while secondary consumers such as snakes would consume the primary consumers.

By so doing, energy flows from one trophic level to the other.

Explanation:

[Do you mean 0.035 kg bullet?]

Since the momentum of the system is conserved,

Let u m/s be the initial velocity of the bullet

0.035u = 8.6(5+0.035)

u ~= 1237.1714 m/s

u = 1240 m/s (3 sig. fig.)

Answer:

 μ = 0.179

Explanation:

For this exercise we use the rotational equilibrium condition, where we set a reference system at the top of the ladder where it is in contact with the parent, we will assume the counterclockwise rotations as positive

         ∑ τ = 0

         W_stairs x/2 + W_man x’+ fr y - N x = 0

          fr y = -W_stairs x/2 - W_man x’ + N x

let's use trigonometry for distances

* the man up the ladder 78%

            l ’= 0.78 L

            cos 59 = x ’/ l’

            x’= 0.78 L cos 59

* the horizontal distance

           cos 59 = x / L

            x = L cos 59

* vertical distance

            sin 59 = Y / L

            y = L sin 59

we substitute

           fr L sin 59 = -W_stairs Lcos59 / 2 - W_man 0.78 L cos59 + N L cos59

           fr sin 59 = - ½ W_stairs cos 59 - 0.78 W_man cos 59 + N cos 59

           fr = ctan 59  (N - ½ W_stairs - 0.78 W_man)     (1)

Let's write the translational equilibrium equations

Y axis  

           N -W_stairs - W_man = 0

           N = W_stairs + W_man

           N = 85 + 21.5 9.8

           N = 295.7 N

we substitute in 1

           fr = ctg 59 (295.7 - ½ 85 - 0.78 21.5 9.8)

           fr = 0.6 (295.7 - 42.5 - 164.346)

           fr = 52.89 N

the expression for the friction force is

            fr = μ N

            μ = fr / N

             μ = 52.89 / 295.7  

             μ = 0.179

A slide projector has a magnification of 50. 12mm or 1.2cm.

Bringing an object as close to the eye as feasible when wishing to observe an object's details is instinctual. The angle that an object subtends at the eye increases with proximity to the eye, making it appear larger.

However, if an item is too near, the eye will no longer be able to generate a distinct image. The creation of a "virtual image" that may be comfortably observed is made possible by the use of a magnifying lens between the observer and the object.

The magnifier should be positioned exactly in front of the eye to provide the clearest image possible. Once a clear image of the thing is present, the object of interest is brought closer to the eye.

Therefore, A slide projector has a magnification of 50. 12mm or 1.2cm.

Answer:

Answer:

Is to add all forces, for example either the gf = gravitational force

Ff= force fiction

Fn= normal force

Thus, fg + ff + fn = y will give you results

Well then the forces you use in your exercises or questions.

The equation for net force is: ΣF = ma

or, ΣF = Δp/Δt.

The definition of force in physics is: The push or pull on a massed object changes its velocity.

An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force.

A spring balance can be used to calculate the Force. Newton is the SI unit of force.

Hence, net force applied on the object = mass × acceleration

ΣF = ma

It can be written in another from as:

net force applied on the object = change in momentum ÷ time interval

ΣF = Δp/Δt

So, the equation for net force is: ΣF = ma

or, ΣF = Δp/Δt.

Answer:

Q = 144612 Joules.

Explanation:

Given the following data;

Mass = 2.6 kg

Initial temperature = -27°C to Kelvin = 273 + (-27) = 246K

Final temperature = 0°C to Kelvin = 273K

Specific heat capacity = 2060 J/kgK.

To find the quantity of heat absorbed;

Heat capacity is given by the formula;

[tex] Q = mcdt[/tex]

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

dt represents the change in temperature.

dt = T2 - T1

dt = 273 - 246

dt = 27 K

Substituting the values into the equation, we have;

[tex] Q = 2.6*2060*27[/tex]

Q = 144612 Joules.

The statement is false because as the temperature of water is decreased from 4C to 0C, expansion occurs.

You should understand that this is very weird behavior for any compound ... within a small temperature range, the stuff actually gets bigger as it gets colder.  That's why cubes float in your sody, and bergs float in the ocean.

Water is one of only two known substances that do this.  And if water didn't do it, then life on Earth would not be possible.  

Hmmm....

There is not contraction, Instead expansion occurs .

We know density of water is temperature dependant .

at 4°C water has max density so least volume as density is indirectly proportional to volume.

at 0°C density decreases so volume increases

Answer:

I think it is difficult to determine what has caused climate change in the distant past because it must have been a long time ago so geologists can't carry out different experiments and figure out what gases the planet had conjured, so geologists can only make predictions based off the evidence they currently have from what the planet looked like before. The planet must have changed over the years, therefore the climate has also changed in the future, so they cannot work with how the planet looked in the past.
