Answer:
<h2>1139.5 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
work done = 265 × 4.3 = 1139.5
We have the final answer as
<h3>1139.5 J</h3>

Hz is the green photon's frequency .
The distance between similar points (adjacent crests) in adjacent cycles of a waveform signal that is propagated in space is known as the wavelength. A wave's wavelength is often measured in meters (m), centimeters (cm), or millimeters (mm) (mm). The relationship between frequency and wavelength is inverse.
<h3>Given:</h3>
Wavelength of green light = 520 nm
f = c / λ
where, f = Frequency
c = Speed of light = 3 × 
m/s
λ = Wavelength of light
∴ f = c / λ
f = 
= 5.77 × Hz
Therefore, 5.77 × Hz is the green photon's frequency .

Sunspots are spot like structure on the surface of sun, they are created due to geomagnetic flux which inhibits the convection of heat waves thus reducing the temperature of spot with some factor
A force of charge that drive around a circuit is call electeons
<span>Radius = 4.6 m
Time for one complete rotation t = 5.5 s.
Distance = 2 x 3.14 x R = 2 x 3.14 x 4.6 m = 28.888.
Velocity V = distance / time = 28.888 / 5.5 s = 5.25 m/s
Force exerted by cat Fc = mV^2 / R = (mx 5.25^2) / 4.6 m
Force of the cat Fc = 6m, m being the mass.
Normal force = Us x m x g = Us x m x 9.81 = Us9.81m
equating the both forces => Us9.81m = 6m => Us = 6 / 9.81 => Us = 0.6116
So coefficient of static friction = 0.6116</span>
