Answer:
a. Amplitude = 0.244 meters
b. Period = 1.62 seconds
c. Frequency = 0.6173 Hz
Explanation:
a.
With the position goes from 0.122 meters to -0.122 meters (negative because it is in the opposite side of the equilibrium point), the amplitude is the maximum value minus the minimum value:
Amplitude = 0.122 - (-0.122) = 0.122 + 0.122 = 0.244 meters
b.
The period is the amount of time the object takes to arrive in the same position again. So, if it takes 0.81 seconds to go to -0.122 m, it will take another 0.81 seconds to come back to 0.122 m, so the period is the sum of these two times:
Period = 0.81 + 0.81 + 1.62 seconds
c.
The frequency of the movement is the inverse of the period:
Frequency = 1 / Period
So if the period is 1.62 seconds, the frequency is:
Frequency = 1 / 1.62 = 0.6173 Hertz
When the core temperature rises, stars start burning helium to carbon. Hydrogen and helium are fused in a shell surrounding the core, raising the temperature.
The most prevalent method of generating energy in the cosmos is hydrogen fusion. The gravitational force is utilised to fuse hydrogen at the centres of our Sun and other stars, where it has a density more than 70 times greater than that of steel. Thus, all of the heat and light on earth comes from fusion. Helium is a chemical element with the atomic number 2 and the symbol He. The first member of the noble gas group in the periodic table, it is a colourless, odourless, tasteless, inert, monatomic gas that is not harmful.

Answer:
less than one light year. We would all be dead if it was more than a light year.
Answer:
v_f = 30 m/s
Explanation:
v_f = v_I + a*t
v_f = 0m/s + (9.81m/s²)*(3s)
v_f = 29.43m/s
v_f = 30 m/s
Since the object is being launched horizontally off the cliff the only vertical force acting on the ball is gravity which is an acceleration of 9.81m/s². So we have all the flowing information to use the the kinematic equation: v_f = v_I + a*t.
