If a photon has a frequency of 1.15 x 10 to the 15 power Hertz what is the energy of the photon given: Planck's constant is 6.63 x 10 to the negative 34 joule seconds

Answers

Answer 1

Answer:

Answer:

7.62 x $10^(-19)$ J

Explanation:

Given:

frequency 'f'= 1.15 x $10^(15)$ Hz

Planck's constant 'h'= 6.63x $10^(-34)$ Js

Energy of photon can be calculated by the formula:

E= hf

Where,

E= energy of photon

f= frequency of photon

h= Planck's constant

Putting the given values in the formula

E= 6.63x $10^(-34)$ x 1.15 x $10^(15)$

E= 7.62 x $10^(-19)$ J

Therefore, the energy of photon is 7.62 x $10^(-19)$ J

Answer 2

Answer:

Explanation:

Given:

Frequency, f = 1.15 × 10^15 Hz

Plancks constant, h = 6.63 × 10^-34 Js

Using the formula,

Energy, E = h × f

Inputting values,

Energy, E = 1.15 × 10^15 × 6.63 × 10^-34

= 7.6245 × 10^-19 J

Energy of the photon , E = 7.6245 × 10^-19 J.

What does the term heat death refer to?a. a danger of increasing entropy
b. the hot and fiery end to the universe
c. the unavailability of energy to do work
d. a theoretical violation of the second law of thermodynamics

Answers

The term heat death refers to a danger of increasing entropy. The correct option among all the options that are given in the question is the first option or option "a". This theory stems from the second law of thermodynamics and it states that entropy tends to increase in any isolated system. I hope the answer helps you.

Answers

Answer: tyre made out of rubber, tread pattern on wheels

Explanation:

the material of rubber generally grips better than other materials whilst still allows the car to move smoothly

tread patterns are essential on all tires as it increases the traction between the wheels and the road which increases the friction

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

In the series circuit, if the current through r1 is 1.5 a, what is the current through r2?

Answers

In a series circuit, the current in all points of the circuit is the same. Hence, current through the resistor r2 is same as that of r1 that is 1.5 amperes.

What is series circuit ?

A circuit is the path through which current is passing which can be of open circuit or closed circuit. There are two ways in which the components are connected in the circuit namely, series and parallel.

In a series circuit, the electrical components are connected in a series fashion. Here, the current is the same in all points of the series circuit. But voltage will be different.

In the case of parallel circuits, the components are connected in a parallel fashion. The current passing through each parallelly connected device will be different.

Here, the two resistors are connected in series. Hence, the current passing through is the same that is 1.5 A for r2 also.

In a series circuit the current is the same in every part of the circuit. So the current through r2 is 1.5A (the same that flows through r1)

How does molecules move in Hot and cold air?

Scientists are working on a new technique to kill cancer cells by zapping them with ultrahigh-energy (in the range of 1012W) pulses of light that last for an extremely short time (a few nanoseconds). These short pulses scramble the interior of a cell without causing it to explode, as long pulses would do. We can model a typical such cell as a disk 5.0μm in diameter, with the pulse lasting for 4.0 ns with an average power of 2.0×1012W. We shall assume that the energy is spread uniformly over the faces of 100 cells for each pulse. (a) How much energy is given to the cell during this pulse? (b) What is the intensity (in W/m2) delivered to the cell? (c) What are the maximum values of the electric and magnetic fields in the pulse?
