Answer:
wavelength is 121.58 nm
Explanation:
given data
wavelength = 230 nm = 230 x m
kinetic energy = 3.35 × J
to find out
wavelength of light that triple the maximum kinetic energy of the electron
solution
we know here Einstein's photo electric equation that is given below
hc / λ = φ + K(maximum)
and here φ will be
φ = (hc) / λ - K(max
imum)
put here h = 6.626 x J.s
and 3.0 x m/s
so φ = (6.626 x )( 3.0 x ) / ( 230 x ) - 3.35 x
φ = 6.2995 x J
so here we have given triple the maximum kinetic energy
so
hc / λ = φ + K(maximum)
λ = hc / ( φ + K(maximum) )
λ = (6.626 x )( 3.0 x ) / ( 6.2995 x + 3 ( 3.35 x ))
λ = 1.215817 ×
so wavelength is 121.58 nm
Answer:
The chemical processes maintaining balance within the living organism
Explanation:
- Homeostasis is a state or mechanism of the internal physical and the chemical conditions that are maintained by the living system. It is a condition that states the optimal functioning of the organism and include variables like body temperature and fluid balances.
Explanation:
It is given that, the magnetic field in a region of space is specified by its x, y, and z components are given by :
Length of the wire, L = 30 cm = 0.3 m (along z axis)
Current flowing through the wire, I = 3.35 A (along -z axis)
Magnetic force is given by :
Since,
|F| = 0.446 N
Direction of force:
Hence, this is the required solution.

The deceleration about g(acceleration due to gravity) will be:
The electromagnetic waves with the greatest frequency
on the spectrum are the ones we call "gamma rays".
The electromagnetic waves with the lowest frequency
on the spectrum are the ones we call "radio waves".
