The gravitational force between two objects is 45,000 N. What will be the gravitational force between the two objects if the dis

tance between the objects is reduced by one-half?
Physics

Nostrana [21]3 years ago
7 0

Answer:

180000 N

Explanation:

According to Newton's law of gravitation

F= G m1 m2 / r^2

This expression shows that if distance is reduced to half the gravitational force will increase 4 times.

Gravity provides a centripetal force on the Moon, helping it stay in orbit around Earth.
Elodia [21]

Answer:

The statement is true.

Both gravity and centrifugal force act on the Moon which causes it get pulled towards Earth (gravity) and get "flung away" so it doesn't hit us (centrifugal force).

What are the units, if any, of the particle in a box wavefunction. What does this mean?
SIZIF [17.4K]

Answer:

  • [\psi]= [Length^{-3/2}]
  • This means that the integral of the square modulus over the space is dimensionless.

Explanation:

We know that the square modulus of the wavefunction integrated over a volume gives us the probability of finding the particle in that volume. So the result of the integral

\int\limits^{x_f}_{x_0} \int\limits^{yf}_{y_0} \int\limits^{z_f}_{z_0} |\psi|^2 \, dz \,  dy \,  dx

must be dimensionless, as represents a probability.

As the differentials has units of length

[dx]=[dy]=[dz]=[Length]

for the integral to be dimensionless, the units of the square modulus of the wavefunction has to be:

[\psi]^2 = [Length^{-3}]

taking the square root this gives us :

[\psi] = [Length^{-3/2}]
