The barrier is cultural differences.
John, growing up in America learned that eye contact is a way of respect and to show you are paying attention.
Where Cho, growing up in Asia, many Asian counties don't have this "custom" to call it that.

Gold has a specific heat of 0.129 J/(g×°C). How many joules of heat energy are required to raise the temperature of 15 grams of

Elodia [21]

Answer:

$\boxed {\boxed {\sf 121.905 \ J }}$

Explanation:

We are asked to find the energy given mass, specific heat, and change in temperature. Therefore, we must use this formula;

$q= mc \Delta T$

The mass is 15 grams and the specific heat is 0.129 J/(g×°C). Let's calculate the change in temperature.

ΔT= final temperature - initial temperature
ΔT= 85 °C- 22°C = 63°C

Now we know all the values:

$m= 15 \ g \ \\c= 0.129 \ J / (g* \textdegree C) \\\Delta T= 63 \ \textdegree C$

Substitue the values into the formula.

$q= (15 \ g)( 0.129 \ J / (g* \textdegree C)) ( 63 \ \textdegree C)$

Multiply the first numbers together. The grams will cancel.

$q= (1.935 \ J/ \textdegree C) ( 63 \ \textdegree C)$

Multiply again, this time the degrees Celsius cancels.

$q= 121.905 \ J$

<u>121.905 Joules</u> are required.

Which type of microscope can produce three-dimensional images of a cell’s surface?

Olegator [25]

The type of microscope that <span>can produce three-dimensional images of a cell’s surface is the electron-scanning microscope. In this type, beam of high-energy electrons is focused to project the correct projection of the cells. The projection of the cells are made up of signals of the surface.</span>
