You drive 773 miles east, then turn around and drive 773 miles west. What is your displacement, to the nearest mile?

Oliga [24]

Answer:0miles

Explanation:

Since they are moving opposite direction we say

Displacement =773-773

Displacement =0miles

Sketch the path that light would take through the slit. Show the beams that are incident on and reflected from the mirror. Draw

satela [25.4K]

This is the path of light through slits.

what are incident light ?

The light that hits a topic is called as incident light. It may originate from an artificial source or from a natural source, like as the sun. Incident light is also light that reflects off a reflector or another surface.

what is light ?

The region of the electromagnetic spectrum that the human eye sees as light, or visible light, is composed of electromagnetic radiation. The Sun is the primary source of natural light on Earth. Fire has historically been a major source of light for people, from ancient campfires to modern kerosene lamps. Electric lighting has largely taken the place of firelight as a result of the development of electric lights and power systems.

Does a spring scale measure weight or mass? Why?

Marat540 [252]

A spring scale measures weight because It works by Hooke's Law, which states that the force needed to extend a spring is proportional to the distance that spring is extended from its rest position. Therefore, the scale markings on the spring balance are equally spaced. A spring scale cannot measure mass, only weight. hope that helped

You want to calculate the displacement of an object thrown over a bridge. Using -10m/s^2 for acceleration due to gravity, what w

tekilochka [14]

given that acceleration due to gravity is a = -10 m/s^2

initial speed will be ZERO

and we need to find the displacement in t = 8 s

now we can use kinematics equation to find the displacement

$\delta y = v_y * t + \frac{1}{2}at^2$

now plug in all values in it

$\delta y = 0* 8 + \frac{1}{2}*(-10)*8^2$

$\delta y = -320 m$

so it will displace downwards by 320 m

Vehicles depreciate in value quickly, unless they are classic antiques or unique cars, which may

Bess [88]

Answer: option 1. decrease in value.

Explanation:

1) Depreciation is a technical term of the accounting and finance disciplines.

2) Yet, you can know from the ordinary language something depreciated is something that has lost value.

3) Most actives (houses, cars, computers, machines) lose value either with time or with use (usually both).

4) Some objects that do not get depreciated are the precious metals and the valuable objects like art and collections (specially rare collections).

5) The depreciation is a lost of value, so the enterprises reflect it in their accounting as a cost.

6) There are several methods of depreciation. The simplest is the linear depreciation with a rescue value.

7) Example: Suppose you think that a car has a lifetime of 5 year, that the rescue value is 20% of its purchase value, and that you choose to depreciate it linearly.

Then, the depreciation year depreciaton is equal to:

[purchase price - rescue value] / number of years = [100% - 20%] / 5 = 80% / 5 = 16% of the original price each year.

Suppose the original price was $ 35,000.

Then, the year depreciation will be 16% × 35,000 = $5,600, which means that the car will value $5,600 less each year.

A table will show you the value of the car each year

year initial value depreciation final value

1 35,000 5,600 29,400

2 29,400 5,600 23,800

3 23,400 5,600 18,200

4 18,200 5,600 12,600

5 12,600 5,600 7,000 ← rescue value

As you see the rescue value is the 20% of the purchase price (20% × 35,000 = 7,000).
