What is Archimedes' Principle?

Archimedes' Principle is a law of physics related to the the ability of an object to float. This is a physical law related to the ability of an object to float that states that any object fully or partially submerged in water and at rest is acted upon in an upward direction, by a force whose magnitude is equal to the weight of the object. Since this force works in the opposite direction, the body/object neither sinks nor rises. If the sunk object displaces as much water as its weight, it does not sink but floats. The best example to explain this law is the ship in the ocean. When the ship enters the ocean, it begins to sink until it has displaced the same amount of ayer which is equal to its own weight, after which it starts to float.

How can you tell if one object has more mass than another does, on a planet without gravity

Serhud [2]

an object is more dense if there is more weight in the same area, its because of the amount of particles and the weight of the particles. eg, 1cm cubed of gold would weigh alot more than 1cm cubed polystyrene, so gold is more dense

Answer:

I would need more electrons 1.3125 10¹⁰ electrons

Explanation:

Static electricity is formed by induced charges in each part of the system, so the net charge does not change.

Let us analyze the situation presented, if the carpet acquires a positive charge, so that it does not alter the total charge in man, it should acquire a negative charge, to have a net negative charge I would need more electrons that have a negative charge.

We can know the number of electrons by a rule of proportions, if an electron has a charge of 1.6 10-19 C for a charge of 2.15 10-9 C how many electrons are needed

# = 2.15 10⁻⁹ /1.6 10⁻¹⁹

# = 1.3125 10¹⁰ electrons

The number is very high for which we will not worry about rounding since the number of electrons must be an integer

A 600 N force acts on an object with a mass of 50 kg. What is the resulting acceleration of the object?

DochEvi [55]

Answer:

<h3>The answer is 12 m/s²</h3>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

$a = \frac{f}{m} \\$
