A force of 36 N pushes a box that is 12.2 kg. The box is sliding horizontally 2.6 m/s to the left. What is the coefficient of friction? (Could you draw a Force Diagram?)
The coefficient of friction on the box sliding to the left is 0.3.
The given parameters;
applied force , F = 36 Nmass of the box, m = 12.2 kgvelocity of the box, v = 2.6 m/sThe acceleration of the box is calculated as follows;
[tex]F = ma\\\\a = \frac{36}{12.2} \\\\a = 2.95 \ m/s^2[/tex]
The coefficient of friction on the box is calculated as follows;
[tex]\mu_k = \frac{a}{g} \\\\\mu_k = \frac{2.95}{9.8} \\\\\mu_k = 0.3[/tex]
Thus, the coefficient of friction on the box is 0.3.

1. When an apple falls towards the earth , the earth moves up to meet the apple. Is this true? If yes , why is the earth's motion not noticeable ?
2. An astronaut is said to be weightless when he/she travels in a satellite. Does it mean that the earth does not attract him / her ? Give reason.
3. What happens to the weight of a body when it is falling freely under the action of gravity ?
Help!! Random/Irrelevant / Plagiarised answers will be reported*
<3 Thanks! :)
Answer:
1.no because the apple fall towards the earth due to gravity.
2.Yes because when he/she is too far from earth the earth's gravity is not strong enough to pull them down and because there is no gravity in space.
3.It falls down and becomes much more heavy.

a spiral galaxy can be described as what type of shape
Spiral galaxies are also known as twisted collection of stars and gas that have often beautiful shape and are made up of hot young stars.
There are various types of galaxies based on their shapes such as spiral, elliptical, oval etc. The spiral shaped galaxies are called spiral galaxies.
What are galaxies?Galaxies are a groups of stars, dust and dark matter which are connected by the gravitational force. There are billions of galaxies in the universe and each containing trillions of stars. The galaxy nearest to earth is milky way.
The spiral structure that radiate from the galactic disc's core and give spiral galaxies their name. The central bulge, at the ends of which the spiral arms originate, is seen to have an additional component in the shape of a bar-like structure in about two-thirds of all spirals.
Nearly the course of the universe's history, the ratio of barred spirals to barless spirals has probably varied, going from only 10% approximately 8 billion years ago to about a quarter 2.5 billion years ago to over two-thirds of the galaxies in the observable universe at the present.

a box has a length of .5 m and a width of .1m. if the box exerts a force of 10 N on the floor, what is the pressure of the box on the floor
Answer:
The pressure of the box on the floor is 200 Pa
Explanation:
Given,
Length of the box=0.5m
Width of the box= 0.1m
∴Area of the box, A= (0.5 X 0.1) sq.m
= 0.05 sq.m
We know,
Pressure, P= F/A
= 10/0.05 Pa
= 200 Pa
∴The pressure of the box on the floor is 200 Pa
