<u>Answer:</u>
Frequency of orange light = Hz
<u>Explanation:</u>
We are given the wavelength of the orange light and we are to find the value of its frequency.
Wavelength of orange light =
We know that:
Speed of light = Frequency of orange light × Wavelength of orange light
Substituting the values in the above formula:
= Frequency of orange light ×
Frequency of orange light = Hz
Answer:
PV = nRT
n and R are constants.
Dimensions of Pressure = ML^-1T^-1
Volume dimensions = L³
It is dimensionally inconsistent or incorrect
In calculating the energy of a photon of light, we need the relationship for energy and the frequency which is expressed as:
E=hv
where h is the Planck's constant (6.626 x 10-34 J s)and v is the frequency.
E = 6.626 x 10-34 J s (<span>7.33 x 10^14 /s) = 4.857 x 10^-19 J</span>

Answer:
The tension force in the supporting cables is 7245N
Explanation:
There are two forces acting on the elevator: the force of gravity pointing down (+) with magnitude (elevator mass) x (gravitational acceleration), and the tension force of the cable pointing up (-) with an unknown magnitude F. The net force is the sum of these forces:
We are given the resulting acceleration along with the mass, i.e., we know the net force, allowing us to solve for F:
The tension force F in the supporting cables is 7245N
