What is the energy of a photon whose frequency is 6.0x10^20 hz?

Answers

Energy of photon is given by formula

E = h\nu

here

h = Planck's constant

h = 6.6* 10^(-34)

\nu = frequency = 6 * 10^(20)Hz

now the energy is given by

E = 6.6*10^(-34) * 6 * 10^(20)

E = 3.96 * 10^(-13) J

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.

a would be the answer because larceny is theft of someone's personal property.

Using newton's second law of motion, if the force on an object is 20n, and its mass is 5g, what is the acceleration? Can someone explain to me in a simple way how to do this? I have tried but the formulas I see are confusing. Thank you :)

Answers

Answer: The acceleration of the object will be 4000 m/s^2

Explanation:

According to second law of motion:

Force(F)=mass(m)* acceleration(a)

Unit of the force: N=kg* m/s^2

According to question we have :

Force = 20 N

Mass of the object = 5 g = 0.005 kg (1 kg =1000 g)

Acceleration = ?

By using the second law of motion = F= ma

20 N= 0.005 kg* a

a=(Force)/(mass)=(20 N)/(0.005 kg)=4000 m/s^2

The acceleration of the object will be 4000 m/s^2

Do 20 divided by 5 and you'll get 4! All you have to do is take the net force (20n) and divide it by the mass (5g) and you'll have the answer! :)

Answers

Both F's are forces, so µ must be unitless/dimensionless.

F[friction] = µ F[normal]

Which one of the following accurately describes the force of gravity

Answers

The force of gravity, also called gravitational force, is the force exerted by the gravity of one object to another object near it. This is dependent on factors like mass of the two objects measured between their centers.
