4 atoms
Explanation:
On the product side, we expect to find 4 atoms of the product.
An atom is the smallest indivisible particle that takes part in a chemical reaction.
An element is a distinct substance that cannot be split-up into simpler substances. Such substances consist of only one kind of atom.
In this reaction we have:
2 elements: Mg O
on the reactant side:
We have two moles of Mg: 2 atoms of Mg
1 mole of oxygen gas: 2 atoms of O
total atoms: 4 atoms
According to the law of conservation of matter "in a chemical reaction, matter is neither created nor destroyed".
We expect to find 4 atoms of products which is MgO on the product side.
2Mg + O₂ → 2MgO + heat

Answer:
Surface waves, in contrast to body waves can only move along the surface. They arrive after the main P and S waves and are confined to the outer layers of the Earth. They cause the most surface destruction. Earthquake surface waves are divided into two different categories: Love and Rayleigh.

Answer:
Explanation:
Given
Four Point charges are Placed at the corner of a square with side length a
Length of diagonal 
Distance of charge from center 
Potential at the center due to four charges is given by
as all the four charges are equal and placed symmetrical about center
Work done required to bring a fifth charge q from infinity to the center of the square
d = distance to which the grocery cart is pushed = 18 m
f = frictional force = 37.5 N
θ = angle of force below the horizontal = 27.5 deg
W = gravitational force in downward direction
Θ = angle between gravitational force in down direction and displacement in horizontal direction = 90
U = work done on the cart by gravitational force
work done on the cart by gravitational force is given as
U = W d CosΘ
inserting the values
U = W (18) Cos90
U = 0 J
