An angular frequency wave ω0 has an average power P0. If your angular frequency increases by 20%, find the percentage by which its power increases.

Answers

Answer 1
Answer:

Answer:

44%

Explanation:

The average power of a wave is directly proportional to the square of the frequency.

P ∝ ω²

Writing a proportion:

P₁ / P₀ = ω₁² / ω₀²

P₁ / P₀ = (1.2 ω₀)² / ω₀²

P₁ / P₀ = 1.44

P₁ = 1.44 P₀

The power increases by 44%.

Which of the following types of energy originates below Earth's surface?A. electrical energy
B. geothermal energy
C. mechanical energy
D. electromagnetic energy

Answers

Geothermal energy. Electromagnetic energy originates at the sun (think UV rays; they are part of the electromagnetic spectrum). Electrical energy technically can be anywhere, as long as there are positive and negative charges. Mechanical energy is like a generator or an engine; there is always something working to get things done/made. I hope this answer and these explanations helped!

Radiation transfers energy by moving matter. Please select the best answer from the choices provideda. True
b. False

Answers

The answer is b. False because radiation transfers energy by the propagation of waves within the electromagnetic spectrum and the travel of photons. Therefore, no matter is moved within this process.

False

Which is an example of larceny? A. taking a man's wallet while threatening him with a firearm. B. taking $50 from an unattended purse. C. stealing a man's car? D. breaking into a home and stealing $10,000 cash

Answers

Taking $50 from an unattended purse is an example of larceny. The correct Option is  B.

What is Larceny?

Larceny is a type of theft that involves the taking of someone else's property without their consent and with the intent to permanently deprive them of it. It is often referred to as "simple theft" and is considered a crime in most legal systems around the world.

Larceny can take many forms, including stealing money or goods from a store, taking personal property from an individual, or taking valuables from an unattended location. The key element of larceny is that the property is taken without the owner's consent, and the perpetrator intends to keep the property permanently.

The severity of the crime of larceny can vary depending on the value of the property stolen and the circumstances of the theft. In many legal systems, larceny is classified as a misdemeanor or a felony, with the latter carrying a more severe penalty.

In addition to criminal penalties, a person convicted of larceny may also be subject to civil lawsuits and may be required to pay restitution to the victim. Overall, larceny is a serious crime that can have significant consequences for both the perpetrator and the victim.

Here in the question,

Larceny is a type of theft that involves the taking of someone else's property without their consent, with the intent to permanently deprive them of it. It is often referred to as "simple theft."

Option A (taking a man's wallet while threatening him with a firearm) is an example of robbery, which involves the use of force or threat of force to take someone else's property.

Option C (stealing a man's car) is an example of grand theft auto, which is a specific type of larceny that involves the theft of a motor vehicle.

Option D (breaking into a home and stealing $10,000 cash) is an example of burglary, which involves unauthorized entry into a building with the intent to commit a crime, such as theft.

Therefore, the correct option that is an example of larceny is B (taking $50 from an unattended purse) as it involves the taking of someone else's property without their consent, with the intent to permanently deprive them of it.

The temperature scale which starts at absolute zero is the _____.Centigrade scale
Celsius scale
Fahrenheit scale
Kelvin scale

Answers

The temperature scale which starts at absolute zero is the Kelvin scale. The correct option in respect to the given question is the last option. William Thompson was the British scientist and inventor that invented the Kelvin scale. William Thompson was also popularly known as Lord Kelvin.His discovery of the Kelvin scale is considered one among the three best scales in use for measuring temperatures.Each measuring unit of this scale is never called a degree but a Kelvin. This specialized scale gives the option of measuring temperature in both centigrade and Fahrenheit.
the temperature that the scale starts at absolute zero is called the Kelvin scale

A gas has an initial volume of 2.5 L at a temperature of 275 K and a pressure of 2.1 atm. The pressure of the gas increases to 2.7 atm, and the temperature of the gas increases to 298 K.The final volume of the gas, rounded to the nearest tenth, is.

Answers

The following information are given:
V1 = 2.5L
T1 = 275K
P1 = 2.1 atm
T2 = 298K
P2 = 2.7 atm
V2 = ?
The formular for solving the equation is: P1V1T1 = P2V2T2
V2 = P1V1T1/P2VT2
V2 = 2.5 * 275 * 2.7 * 298 = 1443.75/804.6 = 1.794
Therefore, V2 = 1.8L.

Its 2.1, I just took the test, the verified answer is wrong.

When driving downhill, your vehicle will accelerate and start moving fast, due to _______________.a. kinetic energy
b. gravity
c. the amount of pressure you put on the accelerator pedal
d. wet pavement

Answers

Correct answer choice is:

B) Gravity


Explanation:


Gravity is a force of attraction that endures within any two bodies, any two groups, any two particles. Gravity is not just the attraction among objects and the Earth. It is because the Earth going around the Sun is in a magnetic stability. The speed of the Earth's action generates a centrifugal force which balances the gravitational force among the Sun and the Earth. Because there is no force to hold it.

B: Gravity.
The force of gravity will pull the car down the hill. The weight/mass of the car also helps this.
