Lyman radiation, it absorbs radio communication signals, and ionization
Answer:
A mirror is scattering light.
Since you already give the equation, we simply identify the given.
With do = 50.0cm and f = 25.0cm, so
di = (50*25)/(50-25) = 50 cm
The answer is A.
Answer:
3.07 m/s
Explanation:
We know that from kinematics equation
and here, a=g where v is the final velocity, u is the initial velocity, a is acceleration, s is the distance moved, g is acceleration due to gravity
Making u the subject then
Substituting v for 6.79 m/s, s for 1.87 m and g as 9.81 m/s2 then
