units.]

Answers

Answer 1
Answer:

The energy of the photon in joules, given that it's has a frequency of 5.48×10¹⁴ Hz is36.33×10¯²⁰ J

Data obtained from the question

  • Frequency (f) = 5.48×10¹⁴ Hz
  • Energy (E) =?

How to determine the energy

  • Planck's constant (h) = 6.63×10¯³⁴ Js
  • Frequency (f) = 5.48×10¹⁴ Hz
  • Energy (E) =?

The energy of the photon can be obtained as follow:

E = hf

E = 6.63×10¯³⁴ × 5.48×10¹⁴

E = 36.33×10¯²⁰ J

Answer 2
Answer:      Using the Planck's Equation, comes:

E=hf \n E=6.63*10^(-34)*5.48*10^(14)*J \n \boxed {E=36.3324*10^(-20)*J}

In a nuclear power plant, _____. energy is released from the nuclei of atoms energy is released from the bonds of molecules energy is released from the electrons of atoms energy is stored in the nucleus of atoms

Answers

In a nuclear power plant, energy is released from the nuclei of atoms. The correct option among all the options given in the question is the first option. Huge amount of thermal energy is released by the breaking of the uranium atoms. This energy is used for turning a turbine that produces electricity. It is a very clean method of producing electricity. 

Answer: energy is released from the nuclei of atoms

Explanation:

Chemical energy is the energy stored in the bonds of molecules.

Nuclear energy is the energy stored in the nucleus of the atom.

Nuclear power plants use heat produced during nuclear fission to heat water which is produced by the splitting of heavy nucleus into lighter elements by release of energy.

The complete nuclear fission reaction is:

A car of mass 1330 kg is traveling at 28 m/s.  The driver applies the brakes to bring the car to rest over a distance of 79 m. Calculate the force acting on the car.

Answers


you could use SUVAT to work out the deceleration and then use F=ma

S= 79m U=28m/s V=0m/s A=? T=n/a

V^2 = U^2 + 2AS  so 0 = 28^2 + 158A  so -158A = 784

A= 4.962 (3dp)

so F = ma = 4.962 *1330 = 6599.494N (3dp)

The longest wavelength within the visible spectrum is _______ light. A. blue
B. orange
C. red
D. violet

Answers

The longest wavelength within the visible spectrum is the redlight. The answer is letter C. It is called visible light because it is theonly light that can be seen by the human eye. Red light is the longestwavelength around 620 to 750 nanometer. It is followed by orange which has awavelength of 590 t 620 nanometer. And then blue which has a wavelength of 450to 495 nanometer. And the shortest wavelength is violet which has a wavelengthof 380 to 459 nanometer.  

The longest wavelength within the visible spectrum is red light. The correct option is C.

The visible spectrum of light consists of different colors ranging from red to violet. Each color corresponds to a different wavelength. Among the given options, red light has the longest wavelength within the visible spectrum.

A. blue: Blue light has a shorter wavelength compared to red light. It is located on the shorter end of the visible spectrum.

B. orange: Orange light has a shorter wavelength compared to red light. It falls between red and yellow on the visible spectrum.

C. red: Red light has the longest wavelength among the visible colors. It is located on the longer end of the visible spectrum.

D. violet: Violet light has a shorter wavelength compared to red light. It is located on the shorter end of the visible spectrum, just after blue.

Therefore, the correct option is C. red as it has the longest wavelength within the visible spectrum.

A fishing boat using sonar to locate fish is employing _____. diffraction
reflection
refraction
interference

Answers

Answer: reflection

Explanation:

SONAR - Sound Navigation and Ranging

It works on the principle of Echo i.e. the reflection of sound. Sound waves are sent out which get bounced off a nearby object. The reflected sound waves is detected and distance to the object is estimated. Sonar is used to detect, navigate or communicate  objects underwater. Thus, a fishing boat uses sonar to locate the fish. It is employing reflection.

The answer is Reflection

An early submersible craft for deep-sea exploration was raised and lowered by a cable from a ship. When the craft was stationary, the tension in the cable was 7000 N {\rm N}. When the craft was lowered or raised at a steady rate, the motion through the water added an 1800 N {\rm N} drag force.Part AWhat was the tension in the cable when the craft was being lowered to the seafloor?Express your answer to two significant figures and include the appropriate units.Part BWhat was the tension in the cable when the craft was being raised from the seafloor?Express your answer to two significant figures and include the appropriate units.

Answers

Answer:

Explanation:

When the craft was stationary , weight will be balanced by tension

T = mg

T = 7000 N

A)

when the craft was being lowered to the seafloor

drag force will act in upper direction , so

T₁ + 1800 = mg

T₁  = mg - 1800

= 7000 - 1800

= 5200 N

52 X 10² N

B)

when the craft was being raised from the seafloor , Tension will act in downward direction

T₂ = mg+ 1800

T₂  = 7000 - 1800

= 8800N
