Answer:
v = 19.2 m/s
Explanation:
In order to find the speed of the string you use the following formula:
(1)
f: frequency of the string = 80.0Hz
v: speed of the wave = ?
L: length of the string = 12.0cm = 0.12m
The length of the string coincides with the wavelength of the wave for the fundamental mode.
Then, you solve for v in the equation (1), and replace the values of the other parameters:
The speed of the wave is 19.2 m/s
The main morphological types of galaxies are elliptical, spiral, and irregular.
Based on their morphology , galaxies have been classified into 3 types namely elliptical, spiral, and irregular.
These galaxies have various sizes and shapes ranging from dwarf galaxies to giant galaxies.
Elliptical Galaxy:
- The shape of it is generally circular
- These are the largest among all the types of galaxies because according to astronomers, it is formed by the merger of other small galaxies.
- Their rotational pattern is symmetric.
Spiral Galaxy:
- A spiral galaxy consists of a bright nucleus surrounded by a thin outer disk forming a spiral shape.
- This type of galaxy is the most common in our universe.
- It is divided into three classes: Spiral a, Spiral b, and Spiral c.
- Their rotational pattern has circular symmetry.
Irregular Galaxy:
- These types of galaxies have no central nucleus and irregular arms which are bluish.
- They don’t have any rotational symmetry.

Letter B because it is gaining more potential energy as it SLOWLY climbs up the hill.
the less motion the more potential energy there is
Answer:
6/2times500=1500
Explanation:
s = d/t which means speed equals distance divided by time.
