The tiny ripples on the soup are not only similar to wind-generated
waves ... they ARE wind-generated waves. This is a big part of the
reason why they bear such an uncanny resemblance.

Answer: Option (c) is the correct answer.

Explanation:

Wind-generated waves means formation of waves at the surface of water or fluid.

For example, when Julio blows air across his hot bowl of soup then tiny ripples he creates are like wind generated waves. As they are moving in circular motion.

Thus, we can conclude that the tiny ripples Julio creates are similar to wind-generated waves.

The temperature and time t given in hours from 0 to 24 after midnight in downtown mathville is given by t=10-5 sin(pi/12 t) degr

Dvinal [7]

Answer:

$T_A_v_g=9.918192559$^{\circ}C$

Explanation:

The problem tell us that the temperature as function of time in downtown mathville is given by:

$T(t)=10-5*sin(\frac{\pi}{12t})$

The average temperature over a given interval can be calculated as:

$T_a_v_g=\frac{T_o+T_f}{2}$

Where:

$T_o=Initial\hspace{3}temperature\\T_f=Final\hspace{3}temperature$

So, the initial temperature in this case, would be the temperature at noon, and the final temperature would be the temperature at midnight:

Therefore:

$T_o=T(12)=10-5*sin(\frac{\pi}{12*12}) =9.890925575$^{\circ}C$

$T_f=T(24)=10-5*sin(\frac{\pi}{12*24}) =9.945459543$^{\circ}C$

Hence, the average temperature between noon and midnight is:

$T_A_v_g=\frac{9.890925575+9.945459543}{2}=9.918192559$^{\circ}C$

What force is needed to move a barrel 45-m if 3600 J of work are accomplished?

lesantik [10]

Answer:

<h3>The answer is 80 N</h3>

Explanation:

The force acting on the object can be found by using the formula

$f = \frac{w}{d} \\$

where

d is the distance

w is the work done

We have

$f = \frac{3600}{45} \\$

We have the final answer as

<h3>80 N</h3>
