The energy of the photon in joules, given that it's has a frequency of 5.48×10¹⁴ Hz is36.33×10¯²⁰ J
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: 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:
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)
its is turning into electrical energy
B. orange
C. red
D. violet
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.

reflection
refraction
interference
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.
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
