We have that the Table for the Factors is

$\begin{center}\begin{tabular}{ |c|c|c| } Mesurements & Multiplying factor \\ Nanometer& 10^{-9} \\ Centimeter& 10^{-2} \\ Micrometer& 10^{-3} \\ Meter& 10^{1} \\ Kilometer& 10^{3} \\ \end{tabular}\end{center}$

From the Question we are told to

Organize the following measurements from smallest to largest

Kilometer,
Nanometer
Centimeter
Meter
Micrometer.

Note that we Determine the multiplying factor by using Metre which is the SI unit of length as the bases

Answer:

Option B

10.36 m/s

Explanation:

Using the first given equation, then velocity=distance/time

Since distance is provided as 200 m and time, t is 19.3 seconds then substituting these figures yields

v=200/19.3=10.3626943

Rounding off to 2 decimal places, then

v=10.36 m/s

Explain the term "avalanche state"

vagabundo [1.1K]

Answer:

The downwind side of an obstacle such as a ridge. The addition of weight on top of a snowpack, usually from precipitation, wind drifting, or a person. An avalanche that releases from a point and spreads downhill collecting more snow - different from a slab avalanche. Also called a point-release or sluff.

A microphone receiving a pure sound tone feeds an oscilloscope, producing a wave on its screen. If the sound intensity is origin

Temka [501]

Answer:

The new intensity = 3.38 × 10⁻⁵ W/m²

Explanation:

Intensity of sound wave:

The intensity of sound is the rate of flow of flow of energy, per unit area, perpendicular to the direction of the sound wave.

Intensity (I) ∝ A²

where I = intensity, A = Amplitude.

∴ I₁/I₂ = A₁²/A²₂............................... equation 1

From the question, the amplitude increase by 30% of the initial

∴ A₂ = A₁ + 0.3A₁ = 1.3A₁, I₁ = 2.00×10⁻⁵ W/m²

∴ (2.00×10⁻⁵)/I₂ = A₁²/(1.3A₁)²

(2.00×10⁻⁵)/I₂ = 1/1.3²

making I₂ the subject of the equation

I₂ = (2.00 × 10⁻⁵)×1.3² = 3.38 × 10⁻⁵ W/m₂

The new intensity = 3.38 × 10⁻⁵ W/m²

A hockey puck moves 22 meters northward, then 16 meters southward, and finally 4 meters northward.

xenn [34]

Answer:

Distance moved = 42 meters

Mag and Dir = 10 meters northward

Explanation:

Distance is total distance traveled which = 22+16+4 = 42 meters

Displacement is the amount of distance moved from the start point to the end point straight line so our equation for the magnitude is 22-16+4 = 10 meters. Then the direction is northward from the start point. This answer would also be a vector because it has a magnitude and direction.

1.45 L of 16°C water is placed in a refrigerator. The refrigerator's motor must supply an extra 10.7 W power to chill the water

Vika [28.1K]

Answer:

The coefficient of performance of the refrigerator is 2.251.

Explanation:

In this case, the coefficient of performance of the refrigerator ( $COP$ ), no unit, is equal to the ratio of the heat rate received from the water to the power needed to work, that is:

$COP = \frac{\dot Q_{L}}{\dot W}$ (1)

$COP = \frac{\rho\cdot V\cdot c_{w}\cdot \Delta T}{\dot W \cdot \Delta t}$ (2)

Where:

$\dot Q_{L}$ - Heat rate received from the water, in watts.

$\dot W$ - Power, in watts.

$\rho$ - Density of water, in kilograms per cubic meter.

$V$ - Volume of water, in cubic meters.

$c_{w}$ - Specific heat of water, in joules per kilogram-degree Celsius.

$\Delta T$ - Temperature change, in degrees Celsius.

$\Delta t$ - Cooling time, in seconds.

If we know that $\rho = 1000\,\frac{kg}{m^{3}}$ , $V = 1.45\times 10^{-3}\,m^{3}$ , $c_{w} = 4187\,\frac{J}{kg\cdot ^{ \circ}C}$ , $\Delta T = 10\,^{\circ}C$ , $\dot W = 10.7\,W$ and $\Delta t = 2520\,s$ , then the coefficient of refrigeration of the refrigerator is:

$COP = \frac{\rho\cdot V\cdot c_{w}\cdot \Delta T}{\dot W \cdot \Delta t}$

$COP = 2.251$

The coefficient of performance of the refrigerator is 2.251.
