The relationship between two quantities that increase or decrease together is called ___

1 answer:

3 0

The relationship between two quantities that increase or decrease together is called directly proportional.

It is a directly proportional relationship because being directly proportional means that if one increases so does the other, and if one goes down so does the other.

The 2nd largest hailstone every measured fell in Aurora, Nebraska, in 2003. The circumference of that hailstone was 16 inches. U

8_murik_8 [283]

Answer:

1. What was the diameter of the hailstone in inches_5.09_ and in cm___12.92___ and in feet ____0.42___?

2. What was the total volume of the hailstone in cubic inches___68.64___ and cubic feet____0.03____?

3. What was the fall velocity of this hailstone in m/s_____2.584____ and in mph___5.78_____?

Explanation:

1. If the circumference (L) of the stone is 16 inches, then from the following equation

$L = 2\pi R$

$R = \frac{L}{2\pi} = \frac{16}{2\pi} = 2.54 ~inches$

$D = 2R = 5.09 ft$

1 inch = 2.54 cm = 0.08 ft, so 5.09 inches = 12..92 cm = 0.42 ft

2. The total volume is

$V = \frac{4}{3}\pi R^3 = \frac{4}{3}\pi (2.54)^3 = 68.64~in^3\\68.64 ~in^3 = 0.03~ft^3$

3. The fall velocity is V = kd, where k = 20 if d is in cm. Let's calculate the fall velocity in cm.

$V = 20*12.92 = 258.4~cm/s = 2.584~m/s$

2.584 m/s = 5.78 mph

What is a standing wave?

tigry1 [53]

A wave in a medium in which each point on the axis of the wave has an associated constant amplitude. The locations at which the amplitude is minimum are called nodes, and the locations where the amplitude is maximum are called antinodes. (most of these aren't my own words but I tried to put some in my own words) :)
