Light is consist of different spectrum of colors called wave lengths. The colors that visible to the naked eye are known as Red, Orange, Yellow, Green, Blue, Indigo, and Violet. These colors are arranged from shortest to longest. The color red that appeared from the other side of the tank signifies that the wavelength that can only pass through the material is red, which is the shortest. Other wavelengths are dispersed into the molecules of the glass, hence it cannot be seen through the other side.
The answer is A because the lighter or heavier the liquid is (in this case it depends) it flows up.
Answer:
Explanation:
It is given that,
Number of turns in the coil, N = 220
Diameter of the coil, d = 4.4 cm
Radius of the coil, r = 2.2 cm = 0.022 m
Magnetic field produced by the poles of magnet, 
Current flowing in the coil, I = 15 A
Let M is the coil's magnetic dipole moment. Its formula is given by :



So, the coil's magnetic dipole moment is
. Hence, this is the required solution.
Explanation:
A concave meniscus,(normally seen) occurs when the molecules of the liquid are attracted to those of the container. This occurs with water and a glass tube. A convex meniscus occurs when the molecules have a stronger attraction to each other than to the container, as with mercury and glass.
Answer:
It allows you to walk faster.
Explanation:
It is the same force that allows you to accelerate forward when you run. Your planted foot can grip the ground and push backward, which causes the ground to push forward on your foot. We call this grip type of friction, where the surfaces are prevented from slipping across each other, a static frictional force.
