Jack and Linda are two friends who live within 10 miles of each other, but they live at different elevations. Jack lives near se

a level and Linda lives 4,000 feet above sea level. What conclusion can you draw about their climates based on this information?
A.Since they are close in distance, they always experience the exact same climate.
B.Jack’s altitude suggests that he experiences lower air pressure than Linda.
C.Linda likely experiences colder climates due to her higher elevation.
D.Linda will experience more rain and Jack will experience more snow.

The answer is C since the higher up you go the colder it gets which is why Linda will experience colder climates.

Answer: C. Linda likely experiences colder climates due to her higher elevation.

Explanation:

Climate varies with distance and altitude. Higher altitude has low air pressure  and colder climate and snowfall where as place close to sea level experience more rain, hotter climate and higher air pressure.

Jack lives near sea level and Linda lives 4000 feet above sea level.

Hence, correct answer is C. Linda likely experiences colder climates due to her higher elevation.

A bat emits a sound at a frequency of 30.0 kHz as it approaches a wall. The bat detects beats such that the frequency of the ech
Alex

Answer:

The speed of the bat is 5.02 m/s.

Explanation:

Given that,

Frequency = 30.0 kHz

Frequency of echo = 900 Hz

We need to calculate the frequency

Using formula of beat frequency

f_{b}=f_{1}-f_{2}

Put the value into the formula

900=f_{1}-30\times10^{3}

f_{1}=900+30000

f_{1}=30900\ Hz

We need to calculate the speed of the bat

Using Doppler equation

f_{apr}=f\times(\dfrac{v_{sound}+v_{observer}}{v_{s}-v_{source}})

Put the value into the formula

30900=30000\times(\dfrac{340+v_{bat}}{340-v_{bat}})

\dfrac{30900}{30000}=\dfrac{340+v_{bat}}{340-v_{bat}}

1.03=\dfrac{340+v_{bat}}{340-v_{bat}}

340\times1.03-340=v_{b}+1.03v_{b}

10.2=2.03v_{bat}

v_{bat}=\dfrac{10.2}{2.03}

v_{bat}=5.02\ m/s

Hence, The speed of the bat is 5.02 m/s.

A battery of constant voltage is connected to a variable resistor. As the resistance of the resistor increases, what happens to
vova2212 [387]

The electric current amount will vary according to the resistance value when connected to a voltage of a power supply. If resistance is reduced, current will increase. So, if the resistance is infinite (open circuit), the current could be considered zero, or infinitesimal small, if the resistance is zero (of infinitesimal small), the current will tend to be the maximum the power supply can provide. Here is the case of the power supply capability, input resistance, capacity to hold and regulate the output voltage to a certain maximum current, etc. Normally when you short circuit (zero ohms resi

You select a rental package that includes a car with an average consumption of 6.00 liters of fuel per 100 km. Considering that
konstantin123 [22]

7.21 USD.

<h3>Further explanation</h3>

<u>Problem:</u>

  • Given in Europe, the average fuel cost is 1.063 euros/liter.
  • A car with an average consumption of 6.00 liters of fuel per 100 km.

<u>Question: </u>

How much (in US dollars) will we spend properly on fuel on our trip? Express the answer numerically in US dollars to three significant figures.

Let us convert the unit price from the euro to USD. Currently, the exchange rate of 1 euro is 1.13 USD.

\boxed{ \ 1.063 \ euro \times \frac{1.13 \ USD}{1 \ euro} = 1.20119 \ USD \ }

The term euro is crossed out.

After currency conversion, the average fuel cost is 1.20119 USD/liter.

We need 6.00 liters of fuel during the trip.

\boxed{ \ 6.00 \ liters \times \frac{1.20119 \ USD}{1 \ liter} = 7.20714 \ USD \ }

The term liter is crossed out.

We rounded up to three significant figures. Hence, the cost that we will spend on fuel on our trip is as much  \boxed{\boxed{ \ 7.21 \ USD \ }}

<em>Want to follow another way? Let's see.</em>

\boxed{ \ 6.00 \ liters \times \frac{1.063 \ euros}{1 \ liter} = 6.378 \ euro \ }

The term liter is crossed out.

\boxed{ \ 6.378 \ euro \times \frac{1.13 \ USD}{1 \ euro} = 7.20714 \ USD \ }

The term euro is crossed out.

We get a similar result, i.e.,

\boxed{\boxed{ \ 7.21 \ USD \ }}
