if light cannot escape from a black hole how can we detect x-rays from such objects

The charge that passes a cross-sectional area of the circuit in 0.44 s when the compressor on an air conditioner draws 22.0 A when it starts up is 9.68 C.

To find the charge that passes a cross-sectional area of the circuit in this time,

we can use the formula Q = I x t, where Q is the charge, I is the current, and t is the time.

We are given that the current when the compressor starts up is 22.0 A and the time it takes to start up is 0.44 s. Therefore, we can plug these values into the formula and get:

Q = 22.0 A x 0.44 s
Q = 9.68 C

Therefore, the charge that passes a cross-sectional area of the circuit in 0.44 s is 9.68 C.



When an air conditioner starts up, its compressor draws a large amount of current for a short period of time. This current surge is known as inrush current or startup current. In this question, we are given the value of the current when the compressor starts up and the time it takes to start up, and we need to find the charge that passes a cross-sectional area of the circuit in this time.

To understand this question, we need to know the formula for calculating charge, which is Q = I x t, where Q is the charge, I is the current, and t is the time. We can use this formula to calculate the charge that passes a cross-sectional area of the circuit in 0.44 s when the compressor on an air conditioner draws 22.0 A when it starts up.

Plugging in the given values into the formula, we get:

Q = 22.0 A x 0.44 s
Q = 9.68 C

Therefore, the charge that passes a cross-sectional area of the circuit in 0.44 s is 9.68 C.

A simple machine that is a flat surface set at an upward angle sloping at any point less than a 90 degree angle is called an inclined plane.

A sloping surface makes up an inclined plane, which is utilized to lift heavy objects. The mechanical advantage of the plane is that less force is needed to drive an item up the slope than is necessary to lift its weight (discounting friction).

As a tool for lifting or lowering a load, an inclined plane, sometimes referred to as a ramp, is a flat supporting surface that is slanted at an angle from the upward direction with one end higher than the other.

When the switch is closed the ammeter reading will: i) increase slightly

When the switch is open, the current flows through only one path in the circuit, from the battery through the resistor and the ammeter and back to the battery. The resistance of the circuit is determined by the resistor, and the current through the circuit is determined by the voltage of the battery and the resistance of the circuit. Since the ammeter reading is 2.0 A, we can assume that the resistance of the circuit is constant and equal to the value of the resistor.

When the switch is closed, a second path for the current is created through the wire that connects the two ends of the ammeter. This second path has a lower resistance than the original path, so the total resistance of the circuit is reduced. The reduced resistance should result in an increase in the current through the circuit, which could cause the ammeter reading to increase slightly.

An electrically charged object can be used to attract any object with an opposite charge.

This is due to the fundamental principle that opposites attract and repel in physics.

Electric charge is a fundamental property of matter that gives rise to electromagnetic interactions. An electric charge, whether positive or negative, produces an electric field that surrounds it. This field exerts a force on any other charge in its vicinity that is either attracted to or repelled from it. Electric charge is a fundamental property of matter that produces a variety of electric phenomena. When the charge is concentrated in a localized region of space, the object is electrically charged. When there is a net accumulation of charge in an object, it becomes electrically charged. An electrically charged object produces an electric field in its vicinity, which exerts a force on other charged objects. An electrically charged object can be used to attract objects with an opposite charge or repel objects with the same charge.

Explanation:

When an electric filament lamp is replaced by a long fluorescent tube, the effect on the shadow formed in the room can be quite noticeable. It will result in shadows that are softer, less defined, and less intense due to the extended linear light source and improved room illumination.

An electric filament lamp typically emits light from a single point source, which results in sharp, well-defined shadows with distinct edges. When an object obstructs the light from a point source, the shadow formed is a clear silhouette of that object, with minimal diffusion or softening of the edges.

On the other hand, a long fluorescent tube produces light from an extended linear source. This means that the light is emitted from multiple points along the length of the tube, which can cause the shadows to appear softer and less defined. The light rays from different parts of the tube can reach the obstructing object at varying angles, resulting in a more diffused shadow with blurry edges.

Additionally, the fluorescent tube emits light more uniformly in all directions, leading to better overall illumination in the room. This can further reduce the intensity of the shadows, making them less prominent compared to the shadows produced by a filament lamp.

In summary, replacing an electric filament lamp with a long fluorescent tube will result in shadows that are softer, less defined, and less intense due to the extended linear light source and improved room illumination.

La Ley de Ohm muestra la relación que existe entre una resistencia, la tensión o voltaje en sus terminales y la corriente que pasa a través de ella.

Explanation:

Answer:

a. The average speed is 4 mi/hr

b. The average velocity is 0 mi/hr

Explanation:

a. The average speed is given by the following formula;

\(Average \ speed = \dfrac{Total \ Distance}{Total \ Time}\)

The given information are;

The time it took for one friend to run to his friend's house = 30 minutes

The distance between the two houses = 3 miles

The time it took for the friend to walk home = 1 hour

Therefore, the distance the friend ran going to his friend's house = 3 miles and the distance the friend walked going back his house = 3 miles

The total distance travelled = 3 + 3 = 6 miles

The total time taken = 1 hour + 30 minutes = 1 hour 30 minutes = 1.5 hours

Therefore;

\(The \ average \ speed = \dfrac{Total \ Distance}{Total \ Time} = \dfrac{6 \ miles }{1.5 \ Hours} = 4 \ miles \ per \ hour\)

The average speed for the entire trip = 4 mi/hr

b. The average velocity is the total change in position divided by the total time taken to make the change or total displacement divided by the total time for the displacement

Mathematically, average velocity is given as follows;

\(The \ average \ velocity = \dfrac{Final \ location - Initial \ location}{Time \ taken \ for \ the \ change \ in \ location}\)

\(The \ average \ velocity = \dfrac{Total \ displacement}{Time \ taken \ for \ the \ change \ in \ location}\)

\(The \ average \ velocity = \dfrac{Total \ change \ in \ location}{Time \ taken \ for \ the \ change \ in \ location}\)

Given that the friend changed his location to his friend's house, a distance of 3 miles he  we have;

Initial change in location of the friend = 3 miles

After which the friend then relocates back to his house (and we know that it is the same journey but in opposite direction, he  we have;

Final change in location of the friend = -3 miles

We are given that he ran to his friend's house and walked back home in a  total time of 1 hour + 30 minutes = 1.5 hours, therefore, we have;

\(The \ average \ velocity = \dfrac{Sum \ total \ of \ change \ in \ location}{Time \ taken \ for \ the \ change \ in \ location} = \dfrac{3 + (-3) }{1.5}\)

\(The \ average \ velocity = \dfrac{3 \ miles + (-3) \ miles }{1.5} = \dfrac{0 \ miles }{1.5} = 0 \ mi/hr\)

The average velocity = 0 mi/hr.

The probability of stopping at a traffic light is about 47.22%.

With 10 traffic lights, expect to be stopped for approximately 5 minutes and 45 seconds along the main street.

(a) To calculate the probability of stopping at a particular traffic light, we need to consider the cycle time of the traffic lights. The cycle time is the total time taken for one complete sequence of green, amber, and red signals. In this case, the cycle time is 55 + 17 + 48 = 120 seconds.

The probability of stopping at a particular traffic light can be calculated by dividing the red signal duration by the cycle time. Therefore, the probability is 48/120 = 0.4 or 40%.

However, in California, no one stops on amber, so we need to exclude the amber duration from the calculation. Therefore, the probability becomes 48/(55 + 48) ≈ 0.4722 or 47.22%.

(b) If there are 10 traffic lights on the main street, we can calculate the expected amount of time spent stopped at traffic lights by multiplying the probability of stopping at each traffic light by the average duration of being stopped.

The average duration of being stopped at a traffic light is the sum of the red signal duration and half of the amber signal duration. So, the average duration is (48 + 17/2) = 56.5 seconds. To find the expected amount of time stopped at traffic lights, we multiply the average duration by the number of traffic lights: 56.5 seconds * 10 = 565 seconds.

Therefore, if you drive all the way down the main street, the expected amount of time you are likely to be stopped at traffic lights is approximately 565 seconds, which is equivalent to 5 minutes and 45 seconds.

Explanation:

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

Mass (m) of Go Kart = 35 kg

Initial velocity (u) = 12 m/s

Distance (s) = 7.2 m

Force (F) =?

Next, we shall determine the acceleration of the Go Kart. This can be obtained as follow:

Initial velocity (u) = 12 m/s

Distance (s) = 7.2 m

Final velocity (v) = 0 m/s

Acceleration (a) =.?

v² = u² + 2as

0² = 12² + (2 × a × 7.2)

0 = 144 + 14.4a

Collect like terms

0 – 144 = 14.4a

– 144 = 14.4a

Divide both side by 14.4

a = – 144 / 14.4

a = – 10 m/s²

The negative sign indicate that the Go Kart is decelerating when the brake was applied.

Finally, we shall determine the force the Go Kart have when the student locked the brake. This can be obtained as follow:

Mass (m) of Go Kart = 35 kg

Acceleration (a) = 10 m/s

Force (F) =?

F = ma

F = 35 × 10

F = 350 N

Thus, the Go Kart has a force of 350 N when the student locked the brake.

a) The isocost curve equation is G = (20000 - 100C)/500. b) The isocost curve equation is G = (30000 - 100c)/500. c) The isocost curve equation is G = (20000 - 100C)/375. d)  The isocost curve equation is G = (20000 - 120C)/500.

To draw the isocost curve showing the different combinations of gas and coal, we need to use the cost per unit values for coal and gas, as well as the given expenditure (TC) and the changes in expenditure or prices.

Let's denote the quantity of coal as C and the quantity of gas as G. The cost per unit of coal is 100, and the cost per unit of gas is 500.

(a) Initial expenditure (TC) of 20000:

To find the combinations of gas and coal that can be purchased with an initial expenditure of 20000, we can use the following isocost equation

TC = 100C + 500G

We can rearrange the equation to solve for G in terms of C

G = (TC - 100C) / 500

Now we can plot the isocost curve with TC = 20000 using the equation above.

(b) Expenditure (TC) increases by 50%

If the expenditure increases by 50%, the new expenditure (TC_new) becomes 1.5 × TC = 1.5 × 20000 = 30000.

We can use the same isocost equation as before, but with the new expenditure value:

TC_new = 100C + 500G

Rearranging the equation to solve for G

G = (TC_new - 100C) / 500

Now we can plot the isocost curve with TC_new = 30000.

(c) Gas price reduced by 25%:

If the gas price is reduced by 25%, the new cost per unit of gas (Gas_new) becomes 0.75 × 500 = 375.

We can use the original isocost equation, but with the new cost per unit value:

TC = 100C + 375G

Rearranging the equation to solve for G

G = (TC - 100C) / 375

Now we can plot the isocost curve with the reduced gas price.

(d) Coal price rises by 20%

If the coal price rises by 20%, the new cost per unit of coal (Coal_new) becomes 1.2 × 100 = 120.

We can use the original isocost equation, but with the new cost per unit value:

TC = 120C + 500G

Rearranging the equation to solve for G:

G = (TC - 120C) / 500

Now we can plot the isocost curve with the increased coal price.

By plotting these isocost curves on a graph with G on the y-axis and C on the x-axis, we can visualize the different combinations of gas and coal that can be purchased at the given expenditures or price changes.
