Answer:

A. .2 M/s2

Explanation:

Force = mass x acceleration

The force is given as 20 N and tthe mass as 100kg

Solve for accelartion as 20/100 = .2

(Also wrong subject this is a Physics problem)

Answer:

The answer is 0.2m/s^2

Explanation:

As we all know that, Force=Mass* Acceleration

So, to make acceleration the subject of the formular, we have Acceleration=Force/mass

And we were given that, Force=20N

Mass=100kg

So, Acceleration= 20/100

=0.2m/s^2

The Quantum Mechanical Model is used to describe:
gayaneshka [121]

The quantum mechanical model is used to describe the energy and most likely location of an electron.

Answer: Option A

<u>Explanation: </u>

The quantum mechanical model leads to the introduction of quantum numbers representing the energy levels, sub-shells, orbitals as well as spin states of the electrons. So according to the quantum numbers we can perfectly define the position and energy of any electron in an element.

According to Pauli’s principle, any two electron cannot be having same set of quantum numbers. So, using the principle quantum number, azimuthal quantum number, magnetic and spin quantum number, we can define the energy and location of an electron in the atom.

The gravitational force between which two objects would be the most difficult to notice? A. The moon and the earth b. The moon a
Ghella [55]

Answer:

d. A water particle and an air particle

Explanation:

The force of gravity (F) between two objects of masses m1 and m2 and separated by a distance r is given as:

F = G\frac{m1*m2}{r^{2} }

where G is the gravitational constant

This force is therefore, directly proportional to the masses and inversely related to the distance between them.

Based on the given options, since the masses of the water and air particles are very small (masses of earth, moon and sun is relatively huge), the gravitational force between them would be negligible and difficult to measure.
