Answer:
Conduction, radiation and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface
Answer:
A. Yes its possible by employing Pythagoras theorem we can see that similar triangles can have similar hypotenuse but different length
B.no it's not possible also from Pythagoras of they have same components it must be the same triangle
Answer:
the speed of the boat is 21.22ft/min
Explanation:
Hello!
To solve this exercise follow the steps below.
1. Draw the complete scheme of the problem (see attached image).
2. As you can see in the image, our goal is to determine the horizontal component of the velocity (Vx) that corresponds to that of the boat, for this the first thing we do is find the alpha angle using the height and the hypotenuse of the triangle.
3. Finally we find the horizontal velocity component using the cosine function
the speed of the boat is 21.22ft/min
