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.

1) how can you show that atmospheric exerts pressure?
2) how do you measure the volume of an irregular solid ? explain an experiment with diagram.
Answer:
1. While boiling replace the cap and allow it to cool. Vapours inside condense and form water creating vacuum above them. Observation - The can crumbles due to air pressure from outside. This proves that air exerts pressure.
2. Measure the volume of the liquid displaced when the object is submerged. Measure the initial volume of water in graduated cylinder. Submerge the irregular object. Measure the final volume of the water.
— The difference between the initial volume and the final volume is the volume of the object.

A cart of weight 20 N is accelerated across a level surface at 0.15 m/s?. What net force acts on
the wagon?
The net force that acts on the cart of wagon is calculated as 3N
HOW TO CALCULATE NET FORCE:
The net force of a body can be calculated by multiplying the mass of the body by its acceleration. That is;Force (N) = weight (N) × acceleration (m/s²)According to this question, a weight of 20N accelerated across a level surface at 0.15 m/s². The net force can be calculated as follows:F = 20 × 0.15
F = 3N
Therefore, the net force that acts on the cart of wagon is calculated as 3N.Learn more at: https://brainly.com/question/18109210?referrer=searchResults

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.

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

why are hydraulic brakes less effective if there is air in the liquid
Answer:
air is compress able
since air can be compressed, then the hydraulics will not work as well. It won't be able to push the object or brake the wheels. Since water cannot be compressed, it is able to push something, that's how hydraulics work.
Explanation:
it reduces pressure and essentially makes the process less effective.

The transformation function of the given exponential function is -1/4, -1, -4, -16, -64. Hence option D is correct.
What is an exponential function?An exponential function is a mathematical relation to find exponential growth or decay for the given data. It represents the constant change in independent variables and gives the same proportional change.
The exponential function is expressed as f(x) = exp (x) or eˣ where x is variable and e is constant which is called the base of the equation.
From the given,
the exponential function f(x) = 1/4, 1,4,16,64
The transformation function G(x) is the inverse of the exponential function and is equal to -1/4,-1, -4,-16,-64.

3.07/1.35 = a
a=2.27m/s^2
