The answer is B) A hand is burned when touching a pot handle

Explanation: the first and last examples are not a direct exchange of heat from one to the other. Meaning that because the soup and stone are being surrounded by heat, they aren’t in as direct of contact as the hand. The hand touches directly to the hot handle and is immediately burned by the exchange of heat

V = 84.78 ft^2

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

V = 3.14 ( 3)^2 (3)

V = 3.14 *9(3)

V = 84.78 ft^2

A plane traveling with the wind travels 900 miles in 5 hours. the return trip is against the wind and takes 9 hours. find the ra
Aneli [31]

Using the relation between velocity, distance and time, it is found that:

  • The rate of the plane in still air is of 140 mph.
  • The rate of the wind is of 40 mph.

<h3>What is the relation between velocity, distance and time?</h3>

Velocity is <u>distance divided by time</u>, that is:

v = \frac{d}{t}

A plane traveling with the wind travels 900 miles in 5 hours, hence:

v_a + v_w = \frac{900}{5}

v_a + v_w = 180

The return trip is against the wind and takes 9 hours, hence:

v_a - v_w = \frac{900}{9}

v_a - v_w = 100

From the first equation, we have that:

v_w = 180 - v_a{/tex]Replacing on the second:[tex]v_a - v_w = 100

v_a - 180 + v_a = 100

2v_a = 280

v_a = 140

[tex]v_w = 180 - 140 = 40{/tex]

Hence:

  • The rate of the plane in still air is of 140 mph.
  • The rate of the wind is of 40 mph.
