Answer:infrared radiation
Explanation:
Most remote control uses infrared radiation
Answer:
The Third Quarter Moon is when the opposite half of the Moon is illuminated compared to the First Quarter. Which half you see lit up depends on where you are on Earth. Only 50% of the Moon is illuminated during its third quarter phase.
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
To determine the force of the system, we use Newton's Second Law of motion which relates force and mass where they are directly proportional and the constant of proportionality is the acceleration. We calculate as follows:
F = ma
F = 10.41 kg ( 6.5 m/s^2 )
F = 67.67 kg m / s^2 or N
