A meteorologist predicts that a warm air mass and a cold air mass will meet over your vacation destination. Neither air mass con

vfiekz [6]

Answer:

The correct answer is C. A stationary front that will cause an extended period of clouds or precipitation means packing rain gear and planning for precipitation during your trip.

Explanation:

The stationary front is a meteorological front on the border of cold and warm air, more common in summer. It is most often the limit of polar and mid-latitude air masses. It usually lasts in place for a maximum of a few days. The stationary front resembles a warm front or a slow cold front. The weather in the stationary front area is variable, often cloudy and often still rainy. In a few days, the stationary front will turn into either a cold or warm front, or its clouds will disintegrate.

Newton’s law of cooling states that for a cooling substance with initial temperature t0, the temperature t(t) after t minutes ca

antoniya [11.8K]

The cooling rate of the substance is approximately 0.0732.

According to the statement, the Newton's law of cooling is defined by the following formula:

$T(t) = T_{s} + (T_{o}-T_{s})\cdot e^{-k\cdot t}$ (1)

Where:

$T_{s}$ - Final temperature, in degrees Celsius.
$T_{o}$ - Initial temperature, in degrees Celsius.
$t$ - Time, in minutes.
$k$ - Cooling rate, in $\frac{1}{min}$ .
$T(t)$ - Current temperature, in degrees Celsius.

Please notice that substance reaches thermal equilibrium when $T(t) = T_{s}$ , that is when temperature of the substance is equal to the temperature of surrounding air.

If we know that $T_{o} = 80\,^{\circ}C$ , $t = 15\,min$ , $T_{s} = 50\,^{\circ}C$ and $T(15) = 60\,^{\circ}C$ , then the cooling rate of the substance is:

$60 = 50 + (80 - 50)\cdot e^{-15\cdot k}$

$\frac{60-50}{80-50}= e^{-15\cdot k}$

$\frac{1}{3} = e^{-15\cdot k}$

$k = -\frac{1}{15}\cdot \ln \frac{1}{3}$

$k \approx 0.0732$

The cooling rate of the substance is approximately 0.0732.

A student wants to use a ramp to move boxes into a truck bed that is 3 m high. He has a choice of 2 different ramps. The length

suter [353]

Answer:

6m ramp

Explanation:

I'm assuming you need the ramp which will make it the easiest which would be the 6m ramp because since it is longer it will be a more gradual incline making it easier to move the boxes.

Answer:

I used the function 1-proportion z-interval on the calculator, where I inputted

Successes(x) = 64
Sample size(n) = 593
Confidence Level(C level) = 0.99

It would result in zInterval_1Prop 64,593,0.99: stat.results, where the values are shown below as:

Lower bound (CLower) = 0.075105
Upper bound (CUpper) = 0.140747
test statistic (p^) = 0.107926
Margin of error (ME) = 0.032821

Therefore, the 99% confidence interval would be around 0.11 ± 0.03 or range from 0.08 to 0.14.
