what is the weight of a 1.8 kg computer
Answer:
17.64 Newtons
Explanation:
In order to find the weight of an object we take the mass in kilograms and multiply it by the gravitational constant (9.8), which is 1.8 * 9.8 = 17.74 Newtons.
Weight is force on the body of given mass 1.8 Kg. Weight is 17.64 N.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Weight of body is force due to gravity,
F = mg
F = 1.8*9.8
F = 17.64 N
Weight of the body is given as 17.64 N.
Weight is force on the body of given mass 1.8 Kg. Weight is 17.64 N.

How is the diametre of a spherical body measured? Explain
Answer:
To measure diameter of a spherical body using Vernier Callipers.A small, movable auxiliary graduated scale attached parallel to a main graduated scale and calibrated to indicate fractional parts of the subdivisions of the larger scale.It is useful tool to measure spherical body.Diameter of a sphere=d = 2 * r , Surface area of a sphere: A = 4 * π * r² , Volume of a sphere: V = 4/3 * π * r³ , Surface to volume ratio of a sphere: A / V = 3 / r .

Explanation:
In the absence of friction, explain why the horizontal component of a projectile’s velocity is a constant.
Answer:
This downward force and acceleration results in a downward displacement from the position that the object would be if there were no gravity. The force of gravity does not affect the horizontal component of motion; a projectile maintains a constant horizontal velocity since there are no horizontal forces acting upon it

how many atoms are in the moon??
The number of atoms on the moon is 1.33× 10¹⁵ atom.
What is an atom?The atom consists of matter that may be split without releasing electrical charges.
It's also the smallest unit of matter with chemical element features. As a result, the atom is the fundamental unit of science.
In the nucleus proton and the neutron is exists. The condition of the atom to be electrically neutral is that the number of the proton and electron should be the same.
The response is 1.33× 10¹⁵ atom. According to the Jefferson Lab of the US Department of Energy.
This answer is derived from an assessment of the number of atoms present in each of the Earth's constituent elements, such as silicon, iron, magnesium, sulfur, and silicon.
Hence the number of atoms on the moon is 1.33× 10¹⁵ atom.

A boy exerts an unknown horizontal force as he pulls a 52 N sled across packed snow. The coefficient of friction is 0.12. If a person weighing 650 N sits on the sled, what force is needed to pull the sled across the snow at constant speed?
Answer:
0.62
Explanation:
Ff = mg = 52 N
Since the speed is constant, the friction
force equals the force exerted by the
girl, 36 N.
Ff = ukFn
so uK = Ff/Fn
= 36 N/52 N
= 0.69
Force is needed to pull the sled across the snow at constant speed is 0.62 N

A piece of wood has a mass of 8g and a volume of 10cm³ work out the density of the wood
Answer:
0.8 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 8 g
volume = 10 cm³
We have
[tex]density = \frac{8}{10} = \frac{4}{5} = 0.8 \\ [/tex]
We have the final answer as
0.8 g/cm³Hope this helps you
A 1.35 kg block is pulled across a
flat, frictionless floor with a 3.07 N
force at 32.0° above horizontal.
What is the acceleration of the block?
Answer:
F=ma
3.07=1.35(a)
3.07/1.35 = a
a=2.27m/s^2
Explanation:
Since the question gives us both the force and mass of the object we can use the f= ma equation and just plug in both the force and mass and just solve for acceleration. I believe the degree listed in the question is just there to throw you off.
