Answer:
the unit of work is derived unit because joule is defined the work done by the force aftab 1 newton causing the displacement of one metre something newton metre(n-m) is also used to measuring work.
<span>Energy = h nu, where nu is the frequency
h = 6.63 x 10^-34 J-s, Planck's constant
So nu = E/h = 1 x 10^5 J /h = 0.15 x 10^29 / s
nu lambda = c, the speed of light.
lambda = wavelength = c / nu =3 x 10^8 / 0.15 x 10^29 = 20 x 10^-21 m.
this can possibly be a gamma ray. Gamma rays are very penetrating. It's both matter and an energy. They are electromagnetic radiation that results from a radioactive material.

Explanation:
Pressure = force / area
P = (68 kg × 9.8 m/s²) / (2 × (0.04 m)²)
P = 208,250 Pa
Converting to psi:
P = 208,250 N/m² × (0.225 lbf/N) × (0.0254 m/in)²
P = 30.2 psi
