Answers

Answer 1

Radio sources are harder to find due to the effectively collect and focus the long-wavelength radio waves to achieve better resolution and sensitivity.

Compared to optical telescopes, radio telescopes are built large primarily because radio waves have very long wavelengths. Due to their long wavelengths, radio waves require larger telescopes to effectively collect and focus the incoming signals. This is necessary to achieve a sufficient level of resolution and sensitivity to detect and study radio sources, which can sometimes be harder to find than optical sources.
The size of a radio telescope is not mainly because they're less expensive to make than optical telescopes. While it is true that radio telescopes do not require the same level of precision and material quality as optical telescopes, building a large radio telescope can still be quite expensive.
Atmospheric turbulence is more of a problem for optical telescopes, as it can distort the incoming light and reduce the clarity of the observed image.

However, radio telescopes are less affected by atmospheric turbulence because radio waves can generally pass through the atmosphere with less distortion.
Lastly, while radio waves can be absorbed by certain parts of the atmosphere, especially at higher frequencies, this is not the primary reason for building larger radio telescopes.

a uniform e-field of magnitude e and directed horizontally fills a region of space. points a through e are all inside the uniform field and form a rectangle with purely horizontal length d and purely vertical height h. point c is in the center of this rectangle. a line from a to c makes an angle of θ with the direction of the e-field. only. Particle 2 is moved by an external force (call it "us") from D to C so that it both starts at rest and ends at rest.
Which of the following statements about particles 1 and 2 are TRUE? You may select more than one.
a. The net work done on particle 1 by the field is zero.
b. The Coulomb force exerted on both particles by the source of the E-field increases as they move fro start to finish.

h. Both particles move through the same potential difference from start to finish.
i. The Coulomb force exerted on particle 2 by the source of the E-field is larger in magnitude that the Coulomb force exerted on particle 1 by the source of the E-field.

Answers

The correct answers are a, d, f, g, and h. The net work done on particle 1 by the field is zero because the electric field is uniform, so the electric force acting on particle 1 is constant.

What is Coulomb force?

Coulomb force is an electrostatic force of attraction or repulsion between two particles that have an electric charge. It is proportional to the product of the charges and inversely proportional to the square of the distance between them.

The Coulomb force exerted on both particles by the source of the E-field increases as they move from start to finish, but the electrical potential energy of particle 2 does not change from start to finish. The E-field at point A when particle 1 is at point A has less magnitude than the E-field at point C when particle 2 is at point C because the magnitude of the electric field decreases with distance from the source. Both particles are at rest when they reach points A and C respectively, and both particles move through the same potential difference from start to finish. Lastly, the Coulomb force exerted on particle 2 by the source of the E-field is larger in magnitude than the Coulomb force exerted on particle 1 by the source of the E-field since particle 2 is closer to the source of the electric field.

An object is placed on a surface. A student tries to apply various combinations of forces on the object. Which pair of forces will not move the object?

Answers

Answer:

See Explanation

Explanation:

The question is incomplete, as there are no diagrams or options to provide more information to the question.

The general explanation is as follows:

For the object not to move

(1): The forces acting on the object must opposite each other. i.e. if force A acts at the right (or positive direction), force B will act at the left (or negative direction).

(2) The two forces must be equal.

So, for instance:

If the pair of forces are 5N and 5N in opposite directions, the object wil not move.

However, if one of the forces is greater, the object will move towards the direction of the greater force.

Prove that acceleration=v/time

Answers

Answer:

Explanation:

Main Answer:

The equation acceleration = v/time can be proven using the fundamental definitions of acceleration, velocity, and time. Acceleration is defined as the rate of change of velocity, and velocity is the rate of change of displacement with respect to time. Let's consider an object moving with an initial velocity v0 and final velocity v in a time interval t.

Explanation:

The change in velocity, Δv, can be calculated as the final velocity minus the initial velocity, Δv = v - v0. Similarly, the change in time, Δt, is the final time minus the initial time, Δt = t - t0.

By substituting these values into the equation for acceleration, we have:

acceleration = Δv/Δt

Now, substituting Δv = v - v0 and Δt = t - t0, we get:

acceleration = (v - v0)/(t - t0)

Since v0 and t0 represent the initial velocity and time, respectively, we can rewrite the equation as:

acceleration = (v - v0)/t

By rearranging the equation, we find:

acceleration = v/t

Thus, we have proved that acceleration is equal to v/time.

The mass of gold plated can then be calculated using the molar mass of gold and the charge passed through the solution is 0.005 g.

What is molar mass?

Molar mass is the mass of one mole of a substance. It is measured in grams per mole (g/mol) and is equal to the molecular weight of the substance. The molecular weight is the sum of the atomic weights of all the atoms in the molecule. Molar mass can be used to calculate the number of moles in a given mass of a substance. It is also used in stoichiometry calculations to determine the amounts of reactants and products in a chemical reaction.

The charge passed through the solution in this case can be calculated using the current and the time:
Charge = Current x Time = 1.5A x 25s = 37.5 C
The mass of gold plated can then be calculated using the molar mass of gold and the charge passed through the solution:
Mass of gold plated = Charge x Molar mass of gold / (6.241 x 10¹⁸ e-) = 37.5 C x 196.967 g/mol / (6.241 x 10¹⁸e-) = 0.005 g.

Namely, sodium ions are far from equilibrium in the resting state. The concentration of sodium inside the cell is 12mM, while outside the cell it is 145mM; the membrane voltage is Vmem = -90 mV. This means that when pumps are turned off, sodium will rush into the cell
Using Ohm's law, find the current per unit area carried by sodium ions just after the pumps have been shut off (5 points). For the conductance of sodium channels per unit area, take the measured value of 0.13Ω-1 m-2. Reexpress your answer as current per unit length along a giant axon, assuming a diameter of 1 mm.

Answers

The current per unit length along the giant axon, assuming a diameter of 1 mm, is approximately -9.18 x \(10^{(-15)\) A/m.

To find the current per unit area carried by sodium ions just after the pumps have been shut off, we can use Ohm's law, which states that current (I) is equal to the conductance (g) multiplied by the voltage (V). In this case, the conductance is the conductance of sodium channels per unit area, given as 0.13 Ω\(^{(-1)} m^{(-2)\). The voltage is the membrane voltage, given as -90 mV.

Given:

Conductance per unit area (g) = 0.13 Ω^\(^{(-1)}m^{(-2)\)

Membrane voltage (V) = -90 mV

Axon diameter = 1 mm = 0.001 m

1. Calculate the current per unit area (I):

I = g * V

I = (0.13 Ω\(^{(-1)} m^{(-2)\) * (-90 mV)

I = -0.0117 A/m²

2. Calculate the cross-sectional area of the axon (A):

A = π * (\(radius)^2\)

radius = 0.001 m / 2 = 0.0005 m

A = π *\((0.0005 m)^2\)

A ≈ 7.85398 x \(10^{(-7)\) m²

3. Calculate the current per unit length along the axon (I'):

I' = I * A

I' = (-0.0117 A/m²) * (7.85398 x \(10^{(-7)\) m²)

I' ≈ -9.18 x\(10^{(-15)\) A/m

Therefore, the current per unit length along the giant axon, after the pumps have been shut off, is approximately -9.18 x \(10^{(-15)\)A/m.

A wire of resistance R is cut into ten equal parts which are then connected in parallel. The equivalent resistance of the combination is

Answers

Answer:

The equivalent resistance of the combination is R/100

Explanation:

Parallel Connection of Resistances

If resistances R1, R2, R3,...., Rn are connected in parallel, the equivalent resistance is calculated as follows:

\(\displaystyle \frac{1}{R_e}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+...+\frac{1}{R_n}\)

The electric resistance of a wire is directly proportional to its length. If a wire of resistance R is cut into 10 equal parts, then each part has a resistance of R/10.

It's known the 10 parts or resistance R/10 were connected in parallel, thus the electric resistance is:

\(\displaystyle \frac{1}{R_e}=\frac{1}{R/10}+\frac{1}{R/10}+\frac{1}{R/10}+...+\frac{1}{R/10}\)

Note the sum consists of 10 equal terms. Operating on each term:

\(\displaystyle \frac{1}{R_e}=\frac{10}{R}+\frac{10}{R}+\frac{10}{R}+...+\frac{10}{R}\)

The sum of 10 identical fractions yields 10 times each fraction:

\(\displaystyle \frac{1}{R_e}=10\frac{10}{R}=\frac{100}{R}\)

Solving for Re needs to take the reciprocal of both sides of the equation:

\(R_e=R/100\)

How much energy is wasted during a fall?

When an object is falling freely, its velocity rises because of the acceleration caused by gravity. In the instance of a body that is falling freely, the kinetic energy thus rises while the potential energy falls as the height of the object decreases.

When an object is descending at its terminal velocity, the force of gravity and air resistance are equal, and the object no longer accelerates. The amount of labor done is equal to the sum of the object's displacement and the gravitational force. The modification of the object's potential energy brought on by gravity can also be used to calculate it.

Regular rhythm, three or more ventricular complexes with QRS complex > 120 milliseconds, ventricular rate between 50 and 110 beats per minute, and sporadic fusion or capture beats are all electrocardiogram features of AIVR. A heart rhythm known as an idioventricular rhythm has a pace of less than 50 beats per minute (bpm), no P waves, and a broadening of the QRS complex. Accelerated idioventricular rhythm is used to describe heart rates between 50 and 110 bpm, while ventricular tachycardia is used to describe rates beyond 120 bpm.

The power developed is 8000 W.

Given data:

Force = 250 N

Distance traveled = 6 m

Velocity = 32 m/s

Let's find out the work done on the object by the applied force.

Work done is given by the product of force and distance covered:

W = F × s

W = 250 × 6 = 1500 J

Thus, the work done on the object by the applied force is 1500 J.

Next, let's determine the power developed.

Power is defined as the rate at which work is done, i.e.,

P = W / t

where P is power, W is work done, and t is time taken to do that work.

We know that velocity = distance / time. Rearranging the above expression, we get:

t = d / v

Substituting the given values, we get:

t = 6 / 32

P = W / t

Substituting the calculated value of W and t, we get:

P = 1500 / (6 / 32)

P = 8000 W
