To find the graphical solution when adding vectors, you can draw a(n) ____ from the starting point to the ending point.
ehidna [41]

Answer:

arrow (which creates the resultant vector)

Explanation:

When you use the graphing technique when adding vectors, you can use the head to tail method to draw the vectors. And from the starting point or the tail of the first vector you drew, you will draw an arrow touching heads with the head of the last vector drawn.

With that, you can use a ruler to measure the resultant vector's magnitude, and use a protractor to measure it's direction.

Below is an example:

Let:

V1 = Vector 1

V2 = Vector 2

R - resultant vector.

ch4aika [34]

Answer:

The grasshopper doesn't have to use it circulatory system to carry gases to and from the grasshopper cells because the air that is passed through the trachea system is already close enough to get to the cells.

Explanation:

"In the grasshopper, exchange of oxygen and carbon dioxide occurs in the tracheal system. Hemolymph plays no part in the process. There is not even an oxygen-carrying pigment in insect hemolymph." - www.biology-pages.info

What happens when light waves passes through glasses
Andreyy89
Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. Light is refracted when it crosses the interface from air into glass in which it moves more slowly. Since the light speed changes at the interface, the wavelength of the light must change, too. The wavelength decreases as the light enters the medium and the light wave changes direction. We illustrate this concept in Figure 3 by representing incident light as parallel waves with a uniform wavelength . As the light enters the glass the wavelength changes to a smaller value '. Wave "a" passes the air/glass interface and slows down before b, c, or d arrive at the interface. The break in the wave-front intersecting the interface occurs when waves "a" and "b" have entered the glass, slowed down and changed direction. At the next wave-front in the glass, all four waves are now traveling with the same velocity and wavelength
