a spider is crawling on a wall. first it crawls 1 meter up, then 1 meter to the left , and then 1 meter down. what is its total displacement?

Answers

Answer 1

Answer:
Displacement means the straight distance from the start point to the
end point, no matter what route was followed along the way.

The spider ends up 1 meter to the left of where he started, so his
displacement for the trip is 1 meter.

If he returns to the place where he started, then his displacement
will be zero.

3. Explain A friend notices that a nail that was left outside for a few month:seems larger and heavier than it was before. He says the nail is rusting disproves the Law of Conservation of Mass. Explain why he is wrong.

Answers

According to the law of conservation of mass of reactants before the reaction must be equal to the mass of the product. He is wrong because the nail is undergoing the process of rusting and after the rusting process mass of the product is increasing.

what is the law of conservation of mass?

According to the law of conservation of mass of reactants before the reaction must be equal to the mass of the product.

What is rusting?

Rusting is a form of oxidation. Rust is formed when iron combines with water and oxygen to generate hydrated ironoxide. Which is given by.

$2Fe + 3O_2= Fe_2O_3$

Nail contains iron when combined with oxygen results in the formation of ferrous oxide which is heavier than iron. That's why the mass of the product is more than the mass of reactants. ]

Hence after a few months seems larger and heavier than it was before.

Explain why the gravitational acceleration of any object near earth is the same matter what was the mass of the object

Answers

It takes greater force to accelerate an object that has more mass. But the gravitational force between the Earth and an object is greater when the object hass more mass. It works out just right to make any object with any mass accelerate at the same rate.

In what way does varying the length of a string of a violin change the vibration and how does this affect the sound that's produced?

Answers

The wavelength is the so-called "fundamental" wavelength, or the "first mode." Thus, the wavelength of the string's vibration is defined by the supports, and has nothing whatsoever to do with mass or elasticity.
