Answer:
Explanation:
Force per unit length between two cables at distance d carrying current I₁ and I₂ can be given by the following expression .
F = 10⁻⁷ x 2I₁ I₂ / d
I₁ = I₂ = 15000 A
F = 10⁻⁷ x 2I₁ I₂ / d
= 10⁻⁷ x 2 x 15000² / 4.5 x 10⁻³ m
= 10000 N .
It will be repelling force ie they will repel each other because current is in opposite direction .
No , we should not be concerned about mechanical strength because force does not depend on it .
<span>The scientist thought that the
atom was the smallest particle in the universe is John Dalton. The answer is
letter B. He established the atomic theory which consists of five; elements are
made of extremely small particles called atoms, atoms of different element have
different sizes, mass and physic – chemical properties, atoms cannot be divided
further, destroyed or created, atoms can combine to form compounds and in
chemical reaction, atoms can be combined, separated or rearranged. J.J.
Thompson discovered the electrons in the atom. Ernest Rutherford discovered the
half – life of an atom and Neils Bohr explain the quantum mechanics.</span>
Acceleration = v2 - v1 / t
a = 80 - 40 / 2
a = 40 / 2
a = 20 m/s²
In short, Your Answer would be 20 m/s²
Hope this helps!
Answer:
Explanation:
opposite charges attract each other, while rubbing the objects together they developed opposite charges which caused them to drift together
