Answer:
Glacial Striations
Explanation:
Glacier is an erosion agent that transports and deposits sediments.
Due to the weight and gradual flow of a glacier, it carves along parts of the mass beneath it, these parts are known as sediments, this movement causes marks to appear on the land beneath it. These marks are called Glacial Striations.
b.) Find the density of the rock dropped into the graduated cylinder.
The volume of the rock dropped into the graduated cylinder is 10 ml. The density of the rock is 2.3 g/ml.
We first determine the volume of the rock dropped into the graduated cylinder. The initial volume of water in the cylinder is 20 ml, and after placing the rock, the total volume increases to 30 ml. Therefore, the volume of the rock is the total volume minus the initial volume of the water, which is 30 ml - 20 ml = 10 ml.
Next, we find the density of the rock. The formula for density is mass/volume. Given that the mass of the rock is 23 grams and the volume is 10 ml, the density of the rock would be mass/volume = 23 grams / 10 ml = 2.3 g/ml.

Wave A will be faster than the wave B because
The frequency of the wave is defined as the cycle completed by the wave per second.
Now it is given in the question:
Frequency of wave A = 250 hertz
The wavelength of wave A= 30 cm
Frequency of wave B = 260 hertz
The wavelength of wave B= 25 cm
Now for finding which wave is faster we will calculate the velocity of the wave.
For Wave A
For wave B
We can see that the velocity of wave A is higher than the velocity of wave B.
Thus wave A will be faster than the wave B because

The first and the third harmonics are predominant because they produce odd partials.
We know that the clarinet is a wind instrument. Wind instruments are those instruments that produce sound when a column of air is vibrated inside the instrument.
The clarinet closely follows the harmonics of a pipe that is open at one end. Hence, the first and the third harmonics are predominant because they produce odd partials.
