Answer:
2.04m/s²
Explanation:
Complete Question
<em>A stationary 10 kg object is located on a table near the surface of the earth. The coefficient of kinetic friction between the surfaces is 0.2. A horizontal force of 40 N is applied to the object. Find the acceleration of the object.</em>
<em />
According to Newtons second law;
\sum F_x = ma_x
F_m - F_f = ma_x
Fm is the applied force
Ff is the frictional force
m is the mass
a is the acceleration
Substitute the given values
40N - nmg = 10a
40 - 0.2(10)(9.8) = 10a
40 - 19.6 = 10a
20.4 = 10a
a = 20.4/10
a = 2.04m/s²
<em>Hence the acceleration of the object is 2.04m/s²</em>
Because of the gravity on earth, and the momentum they get from spinning around the planet.
It can be done by you only as we can't access those data in documents.
Let me show steps
- Read the introduction first.
- See below there are two documents in blue

Answer:
Electrons
<h2>What are electrons?</h2>
An elementary particle that is a fundamental constituent of matter, having a negative charge of 1.602 × 10- 19 coulombs, a mass of 9.108 × 10 - 31 kilograms, and spin of 1/2, and existing independently or as the component outside the nucleus of an atom. It can also be defined as a unit of charge equal to the charge of one electron.
