The planet of an item will remain constant across the planet, but if you give it more mass, the gravitational force increases while the acceleration due to gravity remains constant.
<h3 /><h3>What is the difference between mass and weight?</h3>
The mass of the body is defined as the amount of matter a body has. It is denoted by m and its unit is kg. Mass is the quantity on which a lot of physical quantity depends.
Weight is defined as the amount of force an object exerts on the surface. It is given as the product of mass and the gravitational pull.
Mass is an independent quantity it never depends on the other. While weight is a dependent quantity that depends upon the gravitational pull.
The value of gravitational pull is different in the different parts of the universe. For example, on the earth, the value of gravitational acceleration is 9.81 m/sec².While on the moon it is g/6.
Weight is change according to the place or surrounding while the mass of the body is constant everywhere.
The planet of an item will remain constant across the cosmos, but if you give it more mass, the gravitational force increases while the acceleration of gravity remains constant.
If a planet's gravity weakens, the weight of that planet will likewise be altered. With an increase in mass, weight also rises.
Hence, the gravitational force increases while the acceleration due to gravity remains constant for the given case.

Answer:
The stress S = 1935 [Psi]
Explanation:
This kind of problem belongs to the mechanical of materials field in the branch of the mechanical engineering.
The initial data:
P = internal pressure [Psi] = 90 [Psi]
Di= internal diameter [in] = 22 [in]
t = wall thickness [in] = 0.25 [in]
S = stress = [Psi]
Therefore
ri = internal radius = (Di)/2 - t = (22/2) - 0.25 = 10.75 [in]
And using the expression to find the stress:
![S=\frac{P*D_{i} }{2*t} \\replacing:\\S=\frac{90*10.75 }{2*0.25} \\S=1935[Psi]](https://tex.z-dn.net/?f=S%3D%5Cfrac%7BP%2AD_%7Bi%7D%20%7D%7B2%2At%7D%20%5C%5Creplacing%3A%5C%5CS%3D%5Cfrac%7B90%2A10.75%20%7D%7B2%2A0.25%7D%20%5C%5CS%3D1935%5BPsi%5D)
In the attached image we can see the stress σ1 & σ2 = S acting over the point A.
My Van de Graaff generator will create sparks about 10 to 12 inches in length. I like to charge myself on it and point at the aluminum blinds on the window. The charge (electronic wind) will cause the blinds to move. I can do this from about 8 feet away with ease. Soap bubbles are also interesting to play with around the Van de Graaff generator. They initially are attracted to the Van de Graaff generator and float toward it; once they become charged by the Van de Graaff generator, they float away due to repulsion. There are multitudes of fun things you can do with your Van de Graaff generator. Use your imagination!
That is incorrect friction is able to stop some thing or slow it down so it is the opposite way around. Please put bainliest!
