Answer:
Explanation:
Given
charge of first body
charge of second body
Particle 1 is at origin and particle 2 is at
third Particle which charge +q must be placed left of because it will repel the q charge while will attract it
suppose it is placed at a distance of x m
you can subtract the atomic number from the mass number to find the number of neutrons.
Answer:
hypothalamus
Explanation:
The hypothalamus is known as the master switchboard because it's the part of the brain that controls the endocrine system. The pituitary gland, which hangs by a thin stalk from the hypothalamus, is called the master gland of the body because it regulates the activity of the endocrine glands.
Answer:
I'd say C is the answer they want, though my pedantic side wants to argue for B being true as well.
Answer:
Explanation:
Assuming the pith balls as point charges, we can calculate the repulsive force between them, using Coulomb's law:
We observe that the magnitude of the electric force is directly proportional to the product of the magnitude of both signed charges() and inversely proportional to the square of the distance(d) that separates them.
Replacing the given values, where k is the Coulomb constant:
