Answer:

The answer is: The motion of the medium is parallel to a longitudinal wave and perpendicular to a transverse wave.

Explanation:

As you can see in the image below, the motion of a longitudinal wave is parallel to the medium or object which the wave is traveling, and the motion of a transverse wave is perpendicular.

Raul wants to study how pot size affects the growth of plants. To do this, he intends to purchase three different pots of varyin

hram777 [196]

Answer: The answer position may vary. But the correct answer is D. No; Raul changes more than one variable so the results will be invalid.

Explanation:

Raul's experimental set-up will not produce valid results because he intends to change more than one variable.

One variable that Raul will change is the pot size. According to the description, however, Raul will also change one other variable—the type of flower that is planted. Even though Raul plans on using flowers only, he should use the same type of flower in each pot, not different types.

Valid results are only produced when only one variable is changed at a time.

Astronomers classify stars according to their (1 point) distance from Earth. color, size, and absolute brightness. age and paral

charle [14.2K]

Answer:

All of the above

Explanation:

Astronomers use all of those measures to classify stars. If you want to look more into classifying stars, check out the Hertzsprung-Russel Diagram. It covers how to identify red giants, main sequence, dwarf stars, ect. Distance from earth is typically measured in light years. The color of stars generally determines how hot they are. (Blue stars are the hottest) Also, the parallax method is used to measure stars that are closer to earth. This method relies heavily on geometry though.

Hope this helped!

An object is thrown upward from the top of a 128-foot building with an initial velocity of 112 feet per second. The height h of

lorasvet [3.4K]

Answer:

Time, t = 8 seconds

Explanation:

An object is thrown upward from the top of a 128-foot building with an initial velocity of 112 feet per second. The height h as a function of time t is given by :

$h=-16t^2+112t+128$

We need to find the time when the object will hit the ground. When it will hit the ground, h = 0

So,

$-16t^2+112t+128=0$

On solving the above quadratic equation, we get the value of t = 8 seconds. So, after 8 seconds the object will hit the ground. Hence, this is the required solution.
