Answer:
White light contains seven colors, which are separated by the prism.
White light reacts with chemicals in the air to produce seven colors.
Explanation:
It was first observed by Sir Issac Newton, that when white light is passed through a prism, an elongated, coloured patch of light is obtained on a screen placed behind the prism. The seven colours obtained constitute the spectrum of white light.
In nature, white light is separated into its constituent wavelengths when white light interacts with substances in the atmosphere.
Complete Question
A system consists of a disk of mass 2.0 kg and radius 50 cm upon which is mounted an annular cylinder of mass 1.0 kg with inner radius 20 cm and outer radius 30 cm (see below). The system rotates about an axis through the center of the disk and annular cylinder at 10 rev/s.
(a) What is the moment of inertia of the system
(b) What is its rotational kinetic energy? axis 50 cm 30 cm 20 cm
Answer:
a)
b)
Explanation:
From the question we are told that:
Mass
Disk Radius
Mass of annular cylinder
Inner Radius of cylinder
Outer Radius of cylinder
Angular Velocity
Generally the equation for moment of inertia is mathematically given by
Generally the equation for Rotational Kinetic Energy is mathematically given by
Limestone caves are formed by underground water.
The strength of the electric field is 1.035 * 10^7 N/C.
<h3>What is the electric field?</h3>
The term electric field refers to the region in space where the influence of a charge is felt. Now we know that the electric field is obtained form the formula;
E = F/q
E = electric field
F = electric force
q = magnitude of charge
F = 8.8 * 10^-3 * 10 m/s^2 = 0.088 N
q = -8.5 nc or -8.5 * 10^-9 C
E = 0.088 N/ -8.5 * 10^-9 C
E = 1.035 * 10^7 N/C
