Answer:
Option C
C. It is the slight back-and-forth shifting of star positions that occurs as we view the stars from different positions in Earth's orbit of the Sun.
Explanation:
The angle due to the change in position of a nearby object against the background stars it is known as parallax.
The parallax angle can be used to find out the distance by means of triangulation. Making a triangle between the nearby star, the Sun and the Earth(as is shown in the image below), knowing that the distance between the Earth and the Sun (150000000 Km) is defined as 1 astronomical unit.
(1)
Equation (1) represents the distance in a unit known as parsec (pc).
Key terms:
Parsec: Parallax of arc second
Answer:
The displacement, velocity and time is 20.4 m, -4.52 m/s and 3.624 sec.
Explanation:
Given that,
Initial velocity =15.0 m/s
Height = 10 m
We need to calculate the displacement at 2 sec
Using equation of motion
Put the value into the formula
At 2 sec,
We need to calculate the time
Using equation of motion again
At ground s = 0,
Neglect the negative term because the time is not negative
We need to calculate the velocity
Using formula of velocity
Hence, The displacement, velocity and time is 20.4 m, -4.52 m/s and 3.624 sec.
I would say b7.5kg for the mass of it orbiting around the Saturn because if going around something like the you could only go up in the number not go down so I say b7.5 kg of suger
