Answer:
Ay=v₂t + ½ gt² is the best choice to solve this problem.
The height of the cliff is = 176.4 meters.
Explanation:
Given,
initial velocity = 0m/s as it is dropped vertically
acceleration = g = 9.8 m/s²
time = 6s
Height =?
Using the equation Ay=v₂t + ½ gt², we can calculate Ay, which is the height.
So,
Ay=v₂t + ½ gt²
by substituting v, t, and g, we get:
Ay= 0 × 6 + ½ × 9.8 × 6²
Ay = 0 + 4.9 × 36
Ay = 176.4 m
We need to directly measure the spectral type in order to determine the surface temperature of a star.
<h3>How do you find the properties of a star?</h3>
Astronomers can determine the temperature of a star by looking at its color and spectrum. The apparent brightness of a star describes how luminous it looks to us. The brightness of a star tells us how bright it really is. The luminance can be determined using both the perceived brightness and the distance.
A star's luminosity, or the total amount of energy it emits each second, is determined by two factors: The stellar photosphere's "Effective Temperature," T. the star's total surface area, which is influenced by its radius, R.
Because it controls how much fuel a star has and how quickly it burns it, a star's mass is its most fundamental characteristic. The majority of a star's life is spent burning hydrogen into helium in its core, which generates energy. The star needs to achieve a balance between gravity and outward pressure in order to continue to be "alive."

In my opinion it does. The more water the pot holds, the longer you need to wait for it to freeze. Since there is more water, some parts may not be completely frozen. An experiment you can try is to get an ice cube container and a pot. fill both of them and put them in the freezer for the same amount of time. When you take it out, the ice cubes should be frozen leaving the pot with cold water.
Answer:
Copper
Explanation:
Capacitance is directly proportional to dielectric constant
Aluminium and zinc are highly reactive and have high dielectric contact.
Copper has less dielectric constant hence capacitance will decrease
