Given: Height h = 6 ft  or the vertical component "y" this become the initial height, therefore if you want to know the total height of the stone with respect to the ground. you can just add up the two value below.

           Initial Velocity Vi = 41 ft/s     g = -32.2 ft/s²  acting downward

Require: Height h = ?       

Formula: y = Vf² - Vi²/2g

               y = 0 - (41 ft/s)²/2(-32.2 ft/s²)

               y = -1,681 ft²/s²/(-64.4 ft/s²)

               y =  26.10 ft

A gas undergoes two processes. In the first, the volume remains constant at 0.200 m3 and the pressure increases from 1.00×105 Pa
Alborosie
<h2>The work done = - 2 x 10⁴ J</h2>

Explanation:

In the first case , the volume is kept constant and pressure varies .

In isothermal process  , the work done

W₁ = V x ΔP

here V is the volume of gas and ΔP is the change in pressure

Thus W₁ = 0

Because there is no change in volume , therefore displacement is zero .

In second case pressure is constant , but volume changes

Thus W₂ = P x ΔV

here P is the pressure  and ΔV is the change in volume

Therefore W₂ = 4 x 10⁵ x 5 x 10⁻² = 2 x 10⁴ J

The total work done W = - 2 x 10⁴ J

Because the work done in compression is negative .

Which unit represents a value that is one order of magnitude larger than a decimeter?
Mademuasel [1]

The unit represents a value that is one order of magnitude larger than a decimeter is a meter

<h3>Further explanation </h3>

Magnitude is something that can be measured or counted

The principal amount is the amount that has been determined based on the agreement of the scientists

Derivative magnitude is a quantity derived from the principal amount

There are 7 main quantities that have been determined based on international standards, namely:

  • 1. Length, meters (m)
  • 2. Time, second (s)
  • 3. Mass, kilograms (kg)
  • 4. Temperature, kelvin (K)
  • 5. Light intensity, candela (cd)
  • 6. Electric current, amperage (A)
  • 7. Amount of substance, mol (m)

The length of the principal is to indicate the distance between two points in a place

The symbol is usually expressed in l, length

Length measurements can be used by several measuring instruments such as ruler, caliper length, meter, screw micrometer

The main length unit consists of 7 units other than other units of length such as inches, miles, yards, feet:

  • Kilometers, km
  • Hectometer, hm
  • Dekameter, dam
  • Meters, m
  • Decimeter, dm
  • centimeters, cm
  • millimeters, mm

Each one unit descends then multiplied by 10, and if one unit increases then divided by 10

Conversion of other mass units:

mm millimeters = 10⁻³ m

km kilometers = 10³ m

µm micrometers (mcm) = 10µm

nm nanometers = 10⁻⁹ m

Gm gigameters = 10⁹ m

ρm picometers = 10⁻¹² m

An order of magnitude used base ten number.

If numbers differ by one order of magnitude, so the number is about 10 times different in quantity . If values differ by two orders of magnitude, they differ about 100.

The decimeter unit is located between the centimeter and meter.

Decimeter value = 10⁻¹m, centimeter = 10⁻² m, so that the unit represents a value that is one order of magnitude larger than a decimeter is meter
