Answer:
<h2>Magnitude of the second charge is
</h2>
Explanation:
According to columbs law;
F = 
F is the attractive or repulsive force between the charges = 12N
q1 and q2 are the charges
let q1 = - 8.0 x 10^-6 C
q2=?
r is the distance between the charges = 0.050m
k is the coulumbs constant =9*10⁹ kg⋅m³⋅s⁻⁴⋅A⁻²
On substituting the given values
12 = 9*10⁹*( - 8.0 x 10^-6)q2/0.050²
Cross multiplying
Answer:
Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that is perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres, between the infrared and the ultraviolet.
Here are the 7 from shortest to longest wavelength.
Violet - shortest wavelength, around 400-420 nanometers with highest frequency.
Indigo - 420 - 440 nm.
Blue - 440 - 490 nm.
Green - 490 - 570 nm.
Yellow - 570 - 585 nm.
Orange - 585 - 620 nm.
Red - longest wavelength, at around 620 - 780 nanometers with lowest frequency.
Explanation:
From the calculation and the momentum of the body, the velocity is 62 m/s
<h3>What is momentum?</h3>
The term momentum refers to the product of mass and velocity. Now recall that the rate of change of momentum is equal to the impressed force.
Hence;
7440 kg-m/s = 120 kg * v
v= 7440 kg-m/s/120 kg
v = 62 m/s
