That is a lunar eclipse. At night, when the Earth is between the Sun and the moon, the moon would appear to be red. Just for future reference, a solar eclipse is when the Moon is between the Sun and Earth. Speaking of which, check out the solar eclipse this August!
The approximate volume of table tennis ball is 80 cm³
<h3>What is volume?</h3>
Volume is defined as the amount of space occupied by the three dimensional object. S I unit of volume is m³ or cm³.
To find the volume of tennis ball using graduated cylinder.
Step 1 - Fill the graduated cylinder half or full.
Step 2 - Mark the initial volume of the water i.e. 100 cm³ (Vi)
Step 3 - Put the tennis ball in the graduated cylinder. Some of the water was displaced by the table tennis ball.
Step 4 - Mark the Final volume of the water (Vf) i.e. 180 cm³
Step 5 = Calculate the volume by using Formula
Vb = Vf – Vi = 180 cm³ - 100 cm³ = 80 cm³
Hence the volume of tennis ball (Vb) is 80 cm³

Answer:
On the standing waves on a string, the first antinode is one-fourth of a wavelength away from the end. This means
This means that the relation between the wavelength and the length of the string is
By definition, this standing wave is at the third harmonic, n = 3.
Furthermore, the standing wave equation is as follows:
The bead is placed on x = 0.138 m. The maximum velocity is where the derivative of the velocity function equals to zero.
For this equation to be equal to zero, sin(59.94t) = 0. So,
This is the time when the velocity is maximum. So, the maximum velocity can be found by plugging this time into the velocity function:
