We have that the cricket’s displacement is
From the Question we are told that
Start position 5 meter mark
It jumps to the 10 meter mark.
it jumps back to the 6 meter mark.
Generally the equation for cricket’s displacement. is mathematically given as

Field motion ( as opposed to collision motion) which are forces like gravity. And Static motion ( as opposed to kinetic motion)
Static motion is where an object moves on or around another moving object. (Circular motion)
Hope this helped
Answer:
Ex1.
a) Carbon : atomic number Z = 6 and mass number A = 12
b) Protons = 6; electrons = 6 ; neutrons = 6.
Ex2.
Molar mass of H₂O₂ = 34 g; BaF = 156 g; CO = 28 g.
Explanation:
Ex1.
a) the element with atomic number 6 and mass number 12 is carbon
b) number of protons and electrons in a element is given by its atomic number; and for neutrons its mass number - atomic number (A-Z).
⇒ protons = Z = 6; electrons = Z = 6.; neutrons = A-Z = 12-6 = 6.
Ex2.
Molecular formula of hydrogen peroxide is given by H₂O₂.
⇒ molar mass = 2×mass of hydrogen + 2×mass of oxygen
⇒ molar mass = 2×1 + 2×16 = 34.g
molar mass of BaF = mass of barium + mass of fluoride.
= 137 + 19 = 156 g
molar mass of CO = mass of carbon + mass of oxygen
= 12 + 16 = 28 g
Answer:
(a) 
(b) The force is repulsive
Explanation:
a) According to Coulomb's law, the magnitude of the electrice force that one particle exerts on the other is defined as:
Here k is the coulomb constant, 
and 
are the signed magnitudes of the charges and d is the distance between them.
b) According to Coulomb's law, if the two charges have the same sign, the electrostatic force between them is repulsive.
