Answer:

Output power = 500 KW

Explanation:

Given the following data;

Efficiency = 20%

Input power = 2500 KW

To find the output power;

\( Efficiency = \frac {Out-put \; power}{In-put \; power} * 100 \)

Substituting into the equation, we have;

LET Output power = OP

\( 20 = \frac {OP}{2500} * 100 \)

Cross-multiplying, we have;

\( 20 * 2500 = OP * 100 \)

\( 50000 = OP * 100 \)

\( OP = \frac {50000}{100} \)

Output power = 500 KW

To find the spherical convex mirror radius, learn the focal length and magnitude.

What is focal length?

The focal length of a thin lens in air is measured from the lens's center to its primary foci, also known as focal points. The focal length of a converging lens, such as a convex lens, is positive and determines how far a collimated light beam must travel to focus on a single point.

What is magnitude?

Magnitude typically refers to size or distance. By comparing the size and motion speed of the object, we can relate magnitude to movement. The object's or quantity's size determines its magnitude.

R=0.123m

Focal length E= R/2

E= - 0.0615m.

Therefore, the focal length is 0.0615m.

To calculate the distance Mom will travel, we can use the formula: Distance = Speed × Time. In this case, Mom drives at an average speed of 55 mph for 25 hours.

First, we need to convert the speed to the consistent unit of miles per hour. Since the speed is already given in mph, no conversion is necessary.

Next, we multiply the speed (55 mph) by the time (25 hours) to find the distance traveled.

Distance = 55 mph × 25 hours = 1375 miles.

Therefore, Mom will travel a distance of 1375 miles. This means that if she maintains an average speed of 55 mph for a continuous 25-hour period, she will cover a distance of 1375 miles. It's important to note that this calculation assumes a constant speed throughout the entire journey.

When crystals are pressed along their axis of symmetry, an electric charge is generated. This phenomenon is known as the piezoelectric effect.  

The piezoelectric effect was discovered by Pierre and Jacques Curie, who were French physicists. Piezoelectricity is the property of some materials to generate an electric charge in response to applied mechanical stress.

The charge generated by the piezoelectric effect is proportional to the amount of pressure applied to the crystal, as well as the strength of the crystal. The piezoelectric effect is used in a variety of applications, including microphones, speakers, and sensors.

In microphones and speakers, piezoelectric crystals convert sound waves into an electrical signal or vice versa. In sensors, the piezoelectric effect is used to measure pressure, acceleration, and strain. The piezoelectric effect is also used in medical applications, such as ultrasound technology.

Ultrasound imaging works by transmitting sound waves through the body and measuring the echoes that bounce back. The piezoelectric effect is used to generate and detect these sound waves.

In conclusion, the piezoelectric effect is a fascinating phenomenon that has a wide range of practical applications. It was discovered by Pierre and Jacques Curie in the late 19th century and has since been used in a variety of fields.

Answer:

Total contraction on the Bar  = 1.22786 mm

Explanation:

Given that:

Total Length for aluminum bar = 600 mm  

Diameter for aluminum bar  = 40 mm

Hole diameter  = 30 mm

Hole length = 100 mm

elasticity for the aluminum is 85GN/m² = 85 × 10³ N/mm²

compressive load P = 180 KN = 180  × 10³ N

Calculate the total contraction on the bar = ???

The relation used in  calculating the contraction on the bar is:

\(\delta L = \dfrac{P *L }{A*E}\)

The relation used in  calculating the total contraction on the bar can be expressed as :

Total contraction in the Bar = (contraction in part of bar without hole + contraction in part of bar with hole)

i.e

Total contraction on the Bar = \(\dfrac{P *L_1 }{A_1*E} + \dfrac{P *L_2 }{A_2 *E}\)

Let's find the area of cross section without the hole and with the hole

Area of cross section without the hole is :

Using A = πd²/4

A = π (40)²/4

A = 1256.64 mm²

Area of cross section with the hole is :

A = π (40²-30²)/4

A = 549.78 mm²

Total contraction on the Bar = \(\dfrac{P *L_1 }{A_1*E} + \dfrac{P *L_2 }{A_2 *E}\)

Total contraction on the Bar  = \(\dfrac{180 *10^3 \N }{85*10^3 \ N/mm^2} [\dfrac{500}{1256.64}+ \dfrac{100}{549.78}]\)

Total contraction on the Bar  = 2.117( 0.398 + 0.182)

Total contraction on the Bar  = 2.117*(0.58)

Total contraction on the Bar  = 1.22786 mm

In both scenarios, the concept of power and work is demonstrated. A car engine has more power than a horse because a car engine can do the same amount of work in less time. Raj applied less power than Yasmin because his stacking took more time to do the same amount of work.

Power is defined as the rate at which work is done, which means that the more power applied, the faster work can be done.

In the first scenario, a car engine has more power than a horse because it can do the same amount of work in less time. This is because the car engine can convert energy from fuel more efficiently than a horse can convert energy from food. As a result, the car engine can produce more power and do more work in a shorter amount of time.

In the second scenario, Yasmin completed the task of stacking 10 boxes in 2 minutes, while Raj took 3 minutes to complete the same task. This means that Yasmin applied more power than Raj because she was able to do the same amount of work in less time. This could be due to a variety of factors, such as Yasmin having more experience or strength, or using a more efficient technique.

These scenarios demonstrate that power and work are closely related.

hey, friend! this is the answer, but make sure that, next time, you include the diagram to make it easier for us to help you, okay?

A concave lens forming a larger real or virtual image and Concave mirrors form both real and virtual images. therefore all statements are correct. Therefore these can be interpreted by using Ray diagram.

A ray diagram is a diagram that shows path taken by light in order to see a point on the image of an object. Ray diagram uses lines with arrows to show reflected and incident ray.

A concave lens is a lens that diverges a straight light beam from the source to a diminished, upright, virtual image. It can form both real and virtual images. concave lens has curve on both side. The lens having only one side plane and other is curved inside, the les is called as planoconcave lens.

Concave mirror can form both virtual and real image that depends on the distance between the mirror and object. We get virtual and magnified image When the object is placed very close to the mirror. when distance between the object and mirror is increased, image gets diminished and real.

Both concave lens and mirror form both real and virtual images that's depend on the distance.

There are no immediate substitutes for gasoline as public transportation is often limited and walking, biking, or taking a cab is not always feasible. Therefore, people may continue to purchase gasoline despite an increase in price.

One item that is common in our society that I believe is elastic is fast food. Elasticity is the degree to which changes in price affect demand for a good or service.

Fast food is elastic because it has many substitutes such as restaurants, home-cooked meals, and even other fast-food chains. Fast food is also highly responsive to price changes, which means that a small change in price can cause a large change in demand.

For example, a $1 price increase for a burger meal at a fast-food chain might cause many people to switch to a competitor with a cheaper price. Thus, fast food is an elastic product in our society.One item that is common in our society that I believe is inelastic is gasoline.

Gasoline is an inelastic product because it has few substitutes and people need it for transportation. If the price of gasoline increases, people may continue to purchase it even if it means spending more money because there are few alternative options.

Additionally, there are no immediate substitutes for gasoline as public transportation is often limited and walking, biking, or taking a cab is not always feasible.

Therefore, people may continue to purchase gasoline despite an increase in price.

For example, if the price of gasoline increases by $1, a consumer will still purchase gasoline because they require it to get to work or school. Thus, gasoline is an inelastic product in our society.

One item in our society that I believe is elastic is the price of gasoline  because of  various alternatives to gasoline and the proportion of income spent. An item in our society that I believe is inelastic is medical treatment because of the necessity of medical treatment and lack of substitutes.

Firstly, the availability of substitutes contributes to the elasticity of gasoline. In our society, there are various alternatives to gasoline, such as electric vehicles or public transportation. When the price of gasoline increases, consumers have the option to switch to these substitutes, reducing their demand for gasoline. Conversely, when the price of gasoline decreases, consumers may choose to drive more or purchase larger vehicles, increasing their demand for gasoline. This flexibility in consumer choices demonstrates the elasticity of gasoline.

Secondly, the proportion of income spent on the product also influences the elasticity of gasoline. For many individuals, the cost of gasoline represents a significant portion of their overall budget. When the price of gasoline rises, consumers may have to make adjustments to their spending habits or seek alternative means of transportation to cope with the higher expenses. Conversely, when the price of gasoline decreases, consumers may have more disposable income to spend on other goods and services. This sensitivity to price changes further supports the elasticity of gasoline.

On the other hand, an item in our society that I believe is inelastic is medical treatment. Two determinants of elasticity that contribute to this belief are the necessity of the product and the lack of substitutes.

Firstly, the necessity of medical treatment makes it an inelastic product. When individuals require medical treatment, they often have no choice but to seek the necessary healthcare services regardless of the price. This is especially true for life-saving procedures or medications. The demand for medical treatment is driven by the urgency and importance of preserving one's health, which leads to a less responsive consumer behavior to price changes.

Secondly, the lack of substitutes also contributes to the inelasticity of medical treatment. In many cases, there are limited alternatives or substitutes available for specific medical treatments. For example, if a person requires a specific surgery or medication to treat a condition, they cannot easily switch to a different treatment option to lower their expenses. The lack of viable substitutes reduces consumer choice and makes the demand for medical treatment less responsive to changes in price.

In summary, the price of gasoline is elastic due to the availability of substitutes and the proportion of income spent on the product. On the other hand, medical treatment is inelastic due to its necessity and the lack of substitutes. These determinants of elasticity highlight the different levels of responsiveness to price changes in these two common items in our society.

A convex spherical mirror has a radius of curvature of magnitude 38.0 cm. We have calculated the position of the virtual image and the magnification for object distances of 33.0 cm and 43.0 cm. The images formed are virtual, and the image formed is erect.

A convex spherical mirror has a radius of curvature of magnitude 38.0 cm. The position of the virtual image and the magnification for object distances of 33.0 cm are:

Image location: 22.5 cm

Magnification: 0.58

The magnification formula is given by:

magnification = -v / u

Where ,-u is the object distance-v is the image distance for a concave mirror (negative for virtual image)-v is the image distance for a convex mirror (positive for virtual image)

Therefore, -u = -33 cm

33 cm (as the object is on the same side as the virtual image and the center of curvature)-v

33 = 1 / f (where f is the focal length of the convex mirror, which is half the radius of curvature)

v / 33 = 1 / (38/2)

v / 33 = 0.0263

v = 0.0263

33 = 0.868 cm (up to three significant figures)-

087 cm

The position of the virtual image is 0.87 cm in front of the mirror. Since the image is virtual, it is formed behind the mirror. Therefore, the sign of the answer is negative. Magnification is given by:

magnification = -v / u= -0.868

33= -0.0263

Magnification is equal to -0.0263.

The position of the virtual image and the magnification for object distances of 43.0 cm are:

Image location: 31.4 cm

Magnification: 0.93The magnification formula is given by:

magnification = -v / u

Where, -u is the object distance-v is the image distance for a concave mirror (negative for virtual image)-v is the image distance for a convex mirror (positive for virtual image)

Therefore, -u = -43 cm (as the object is on the same side as the virtual image and the center of curvature)-v / 43 = 1 / f (where f is the focal length of the convex mirror, which is half the radius of curvature)

v / 43 = 1 / (38/2)-v / 43

0.0263-v

0.0263 × 43 1.13 cm (up to three significant figures)

The battery is 3 volts and the resistor is 100 ohms. The ammeter has a fuse that blows when you try to put too much current through it, like more than 10 amps. The current through the ammeter is 0.03 amps.

In order to determine the current through the ammeter, we can use Ohm's law, which states that current (I) is equal to voltage V divided by resistance (R), Or I= V/R.In this case, the voltage of the battery is 3 volts and the resistance of the resistor is 100 ohms. therefore the current through the circuit is :I = V/R I = 3/100 I = 0.03 amps.

Since the ammeter has a fuse that blows when the current exceeds 10 amps and the current in this circuit is only 0.03 amps, there is no risk of blowing the fuse. The ammeter will simply measure the current flowing through the circuit, which is 0.03 amps.
