Answer:
<em>The energy of an individual photon that comes out of the laser pointer is 1.91 eV</em>
Explanation:
The energy of a photon can be obtained using the expression below
E = hc/λ
where E is the energy;
h is the Planck's constant = 6.626 x 10-34 Js;
c is the speed of light = 3.00 x m/s (speed of light);
λ is the wavelength = 650 nm =650 x m.
E = (6.626 x 10-34 Js) x (3.00 x m/s) /650 x m
E = 3.058 x J
1 joule = 6.242 x eV
3.058 x J = 3.058 x J x 6.242 x eV = 1.91 eV
Therefore the energy of an individual photon that comes out of the laser pointer is 1.91 eV
Answer:
The distance between adjacent antinodes of the standing wave is 1.25 m.
Explanation:
Given that,
Frequency f= 120 MHz
We need to calculate the distance between adjacent antinodes of the standing wave
Using formula of distance
.....(I)
We know that,
Put the value of in to the equation (I)
Where, c = speed of light
f = frequency
Put the all value into the formula
Hence, The distance between adjacent antinodes of the standing wave is 1.25 m.
The angular speed of the minute hand of a watch is:
-- one revolution per hour
-- 2 pi radians per hour
-- 360 degrees per hour
-- 6 degrees per minute
-- 0.1 degree per second
Answer:
The answer to your question is: F = 50 N
Explanation:
Data
mass = 1000 kg
acceleration = 0.05m/s2
F = ?
Formula
F = m x a
Substitution
F = 1000 kg x 0.05 m/s2 = 50 kgm/s2 = 50 N
Mike is applying a force of 50 N to the car.
