Coulomb's law, or Coulomb's opposite square law, is a trial law of material science that measures the measure of power between two stationary, electrically charged particles. The electric power between charged bodies very still is customarily called electrostatic power or Coulomb power.
The specific gravity is how the density of the object compares to the density of water. Water's density is 1gram per milliliter. We just need to figure out the density of the object.
The object is .8 kg and it displaces 500mL of water, so the density is the mass divided by the volume. Since the density of water is given in grams, we have to convert the objects mass from kg to g and then we can get the density.
.8kg * 1000g/kg = 800 grams
So
800g/500ml = 1.6grams/mL this is the density.
So divide the density of your object by the density of water, which is 1g/mL, you get 1.6 as the specific gravity. This means the object is 1.6 times more dense than water.
Answer: A neutral atom much have an equal number of protons and electrons if not it would not work.
Explanation: (Have a Pleasurable day mate.)
Answer:
The interference pattern from a diffraction grating will have a wide, central bright band with alternate dark and bright bands on both sides, and the interference pattern will have an equally spaced dark and bright band.
Explanation:
In diffraction pattern we know that the distance between two consecutive minimum position is maximum
So here position of minimum is given as
now we have central maximum is of maximum width while all other have width of decreasing order.
While when we use Young's double slit pattern then we can say that position of all maximum and minimum intensity on the screen will be at same distance.
so here we have
so all the maximum and minimum intensity will have equal width.
