Answer: \(200\Omega\)

Explanation:

Given

The battery used is 6V in magnitude

The current flow is 90 mA

If the resistance of A is \(100\Omega\)

Net resistance of the circuit is

\(R_{net}=\dfrac{V}{I}\\\\\Rightarrow R_{net}=\dfrac{6}{90\times 10^{-3}}\\\\\Rightarrow R_{net}=\dfrac{200}{3}\Omega\)

If A and B are in parallel then their net resistance must be   \(\frac{200}{3}\)

\(\dfrac{1}{\frac{200}{3}}=\dfrac{1}{100}+\dfrac{1}{R_b}\\\\\Rightarrow \dfrac{1}{R_b}=\dfrac{3}{200}-\dfrac{1}{100}\\\\\Rightarrow \dfrac{1}{R_b}=\dfrac{3-2}{200}\\\\\Rightarrow R_b=200\Omega\)

Explanation:

Answer:

(1) The relationship between the altitude height, 'h', and the orbital speed, \(v_{orbit}\), of the satellite is an inverse relationship

\(v_{orbit}\) = 1/(h + R)

(2) The height of the satellite, is approximately 24,442 meters

(3) Please find attached the drawing showing the two lines that indicate the direction of the gravitational force on the satellites created with Microsoft Visio

Explanation:

(1) From the given data table, as the altitude increases, the orbital velocity decreases, therefore, the relationship between altitude, 'h', and orbital velocity, '\(v_{orbit}\)', is an inverse relationship which can be expressed as follows;

\(v_{orbit} = \sqrt{\dfrac{G \cdot M}{r} }\)

Where;

G = The universal gravitational constant

M = The mass of the Earth, or planet about which the satellite orbits

r = The distance between the center of the planet and the satellite = h + R

R = The radius of the planet

When \(v_{orbit}\) = 27,500, h = r - R = 1000

We have;

\(v_{orbit}\)² ∝ 1/r

\(v_{orbit}\)² = k/r = k/(R+ h)

When, \(v_{orbit}\)² = 27,500² = 756,250,000

r = h + R = 1000 + R

∴ 756,250,000 = k/(1000 + R)

(1,000 + R) × 756,250,000  = k

When, \(v_{orbit}\)² = 18,000² = 324,000,000

r = h + R = 10,000 + R

∴ 324,000,000 = k/(10,000 + R)

324,000,000 = ((1,000 + R) × 756,250,000)/(10,000 + R)

∴ 324,000,000×(10,000 + R) = (1,000 + R) × 756,250,000

R × (756,250,000 - 324,000,000) = 324,000,000×10,000 - 1,000 × 756,250,000

R = (324,000,000×10,000 - 1,000 × 756,250,000)/(756,250,000 - 324,000,000) = 5746.09600925

R = 5,746.09600925

k = (1,000 + R) × 756,250,000  = (1,000 + 5,746.09600925) × 756,250,000 = 5.1017351 × 10¹²

k = 5.1017351 × 10¹²

(2) When, \(v_{orbit}\) = 13,000 m/s, we have;

13,000² = 5.1017351 × 10¹²/(5,746.09600925 + h)

∴ 5,746.09600925 + h = 5.1017351 × 10^(12)/(13,000²) = 30187.7816568

h = 30187.7816568 - 5,746.09600925 = 24,441.6856476

The height of the satellite, h ≈ 24,442 meters

(a) The visibility at point P will be 0.4 if the electric field vectors of the two waves are parallel.

(b) The visibility at point P will be 1.0 if the electric field vectors of the two waves are perpendicular.

The visibility of interference fringes is given by the formula: V=(I_max-I_min)/(I_max+I_min), where I_max is the maximum intensity and I_min is the minimum intensity.

In case (a), when the electric field vectors of the two waves are parallel, the two waves will interfere destructively at some points on the screen, resulting in a minimum intensity of I_min=-2.6. The maximum intensity of I_max=2.6 occurs at some other points where the two waves interfere constructively. Plugging these values into the formula for visibility, we get V=0.4.

In case (b), when the electric field vectors of the two waves are perpendicular, the two waves will interfere constructively at all points on the screen, resulting in a minimum intensity of I_min=0. The maximum intensity of I_max=2.88 occurs when the two waves are in phase. Plugging these values into the formula for visibility, we get V=1.0, which means that the interference fringes are completely visible.

SONET, or Synchronous Optical Network, is a high-speed communication technology used for transmitting large volumes of data over fiber-optic cables. SONET's extraordinary performance results from its use of a double-ring topology, which provides a high level of redundancy and fault tolerance.

In a double-ring topology, two separate rings are formed, with data being transmitted in opposite directions on each ring. This redundancy ensures that if one ring is broken or damaged, data can still be transmitted through the other ring, ensuring uninterrupted communication.

Additionally, SONET uses fiber-optic cables, which have a much higher bandwidth than traditional copper cables, enabling faster data transmission rates. The use of fiber-optic cables also ensures that data is transmitted over long distances without any loss of signal strength, making it ideal for long-haul communication.

Overall, SONET's extraordinary results are due to its combination of a double-ring topology and fiber-optic cables, which provide a high level of reliability, fault tolerance, and fast data transmission rates, making it a popular choice for high-speed data communication networks.

The original volume of the hydrogen sample was 0.2997 L if a sample of hydrogen at 1. 65 atm had its pressure decreased to 0. 454 atm producing a new volume of 755 ml.

We can use the Ideal Gas Law to find the original volume of the hydrogen sample. The Ideal Gas Law states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the temperature. Assuming that the temperature remains constant, we can write:

P1V1 = P2V2

where P1 is the initial pressure of 1.65 atm, V1 is the initial volume, P2 is the final pressure of 0.454 atm, and V2 is the final volume of 755 mL. Converting the volumes to liters and the pressures to atmospheres, we have:

V1 = (P2V2) / P1

V1 = (0.454 * 0.755) / 1.65

V1 = 0.2997 L

So, the original volume of the hydrogen sample was 0.2997 L.

When a car is skidding to a stop with locked wheels, the main forces acting on the car are the frictional force and any external forces (such as gravity or wind) that may be present.

As the car skids, the frictional force between the locked wheels and the road surface opposes the car's motion and acts in the direction opposite to the car's velocity. This frictional force is static friction, which is responsible for providing the necessary deceleration to bring the car to a stop.

Since the wheels are locked, there is no rolling friction, and the entire frictional force is due to sliding or kinetic friction. The magnitude of the frictional force can be calculated using the equation

Frictional force = coefficient of kinetic friction * normal force

The normal force is the force exerted by the road surface on the car, which is equal to the car's weight (mass * acceleration due to gravity) if the car is on a level road.

As the car skids, its velocity decreases due to the deceleration provided by the frictional force until it comes to a stop. The distance traveled during the skid can depend on various factors such as the initial velocity, coefficient of kinetic friction, and the time it takes for the car to stop.

It's important to note that skidding to a stop with locked wheels is not an ideal or recommended way to stop a car. It can result in a loss of control, increased stopping distance, and potential damage to the tires and road surface. Proper braking techniques using the car's braking system are preferred for safe and controlled deceleration.

The  answer to the question of finding the total magnification of a microscope is the product of the magnifying power of the eyepiece and the magnifying power of the objective.

it is important to note that a microscope is an optical instrument that uses a lens or a combination of lenses to produce magnified images of small objects. The magnification produced by a microscope is the ratio of the size of the image to the size of the object.

The total magnification of a microscope is the magnification produced by the objective lens and the eyepiece. The objective lens is responsible for producing an enlarged image of the specimen on the stage of the microscope. The magnified image is then further enlarged by the eyepiece, which produces an image that is seen by the observer.

To find the total magnification of a microscope, you need to multiply the magnification of the objective lens by the magnification of the eyepiece. The magnification of the objective lens is usually engraved on the lens itself, while the magnification of the eyepiece is usually printed on it.

Once you know the magnification of both the objective and the eyepiece, you can simply multiply them to find the total magnification of the microscope.

In conclusion, to find the total magnification of a microscope, you need to multiply the magnification of the objective lens by the magnification of the eyepiece. The magnification produced by a microscope is the ratio of the size of the image to the size of the object.

What is the meaning of acceleration?

The rate at which velocity changes is called acceleration. Acceleration typically indicates a change in speed, but not necessarily. An item that follows a circular course while maintaining a constant speed is still moving forward because the direction of its motion is shifting.

The three different types of accelerated motions are uniform acceleration, non-uniform acceleration, and average acceleration. The motion in which an item moves in a straight line while increasing in velocity at regular intervals is referred to as uniform acceleration.

s =  1/2 a1 t1^2 +a1 t1 t2 +(a1 t1)^2/a2 - a2/2(a1 t1/a2)^2

The magnetic field tilts of Earth and Uranus are considered to be the most unusual when compared to other celestial bodies in our solar system. Earth's magnetic field tilts at an angle of approximately 11 degrees with respect to its rotational axis, which is quite significant. The magnetic field is generated by the motion of molten iron in the Earth's outer core, which creates a magnetic dipole that is tilted with respect to the planet's rotation axis.

Uranus, on the other hand, has an extremely tilted magnetic field that is almost perpendicular to its rotational axis. This is believed to be due to the planet's unique orientation, as Uranus rotates on its side compared to the other planets in our solar system. The magnetic field is thought to be generated by a layer of electrically conductive fluids deep within the planet's interior, which may be influenced by the unusual orientation of Uranus.

Overall, the magnetic field tilts of Earth and Uranus are intriguing and unique in their own ways, providing valuable insights into the magnetic processes that occur within these celestial bodies.

Answer:

\(36 g/cm^{3}\)

Explanation:

In order to find the density, the problem says we need to find the volume first.

Since we know that the sample of gold is a perfect cube, we know that the side lengths will all be the same. Since all the side lengths will be 3, we can take that value and cube it to find the volume.

\(3^{3} = 27\)

Now that we know the volume is 27 cm³, we can solve find the density.

\(Density = \frac{Mass}{Volume}\)

\(Density = \frac{972g}{27cm^{3} } = 36 g/cm^{3}\)

Therefore, the density of the sample is 36 g/cm³.

It wasn't necessarily the 100N.  That's just the weight of the bike. But you know that you can push a car, a wagon, or a bicycle hard, you can push it not so hard, you can give it a little push, you can give it a big push, you can push it strong, you can push it weak, you can push it medium.  The harder you push, the more it'll accelerate, but it's completely up to you how hard you want to push.  That's what's so great about wheels !  That's why they were such a great invention ! This is where I made my biggest mistake. This guy came into my store one day and said he's got this great invention, it's definitely going to take off, it'll be a winner for sure, he called it a "wheel".  I looked at it, I turned it over and I looked on all sides. I thought it was too simple.  I didn't know then it was elegant. I threw him out.  I was so dumb.  I could have invested money in that guy, today I would have probably more than a hundred dollars.

Anyway, can we figure out how much force the student used to push with ?  Stay tuned:

-- The bike covered 15 meters in 5 seconds.  Its average speed during the whole push was (15m/5s) = 3 meters/sec.

-- If the bike started out with no speed, and its average speed was 3 m/s, then it must have been moving at 6 m/s at the end of the push.

-- If its speed increased from zero to 6 m/s in 5 seconds, then its acceleration was (6m/s / 5 sec) = 1.2 m/s²

-- The bike's weight is 100N.  

(mass) x (gravity) = 100N

Bikemass = (100N) / (9.8 m/s²)

Bikemass = 10.2 kilograms

-- F = m A

Force = (mass) x (acceleration)

Force = (10.2 kg) x (1.2 m/s²)

Force = 12.24 N

-- Work = (force) x (distance)

Work = (12.24 N) x (15 m)

Work = 183.67 Joules

-- Power = (work done) / (time to do the work)

Power = (183.67 joules) / (5 seconds)

Power = 36.73 watts
