Answer:
B. get smaller
Explanation:
The parallax angle of a star measured with respect to the Earth is inversely proportional to the distance of the star from the Earth:

where
is the parallax angle, measured in arcsec
d is the distance between the star and the Earth, measured in parsec
Therefore, if the star Alpha Centauri is moved farther from Earth, then d increases, and therefore the parallax angle will get smaller.
Which is a substance that takes the shape and volume of its container?
liquid
Yep. I think I can.
Horizontal motion doesn't speed up or slow down.
distance = (speed) x (time)
5.4 m = (3.5 m/s) x (time)
Divide each side
by 3.5 m/s: (5.4 m) / (3.5 m/s) = time
time = 1.543 seconds (rounded) .
That's how much time the stone took to fall from the bridge to the water.
Now we can go on to the vertical distance:
Do you remember this physics formula for falling distance ?
Distance = (1/2) (gravity) (time)²
Distance = (1/2) (9.8 m/s²) (1.543 sec)²
= (4.9 m/s²) x (2.38 sec²)
= 11.7 meters .
Explanation:
Impulse = change in momentum
FΔt = Δp
(53 N) (15 s) = Δp
Δp = 795 kg m/s
For constant mass:
Δp = m Δv
795 kg m/s = (12 kg) Δv
Δv = 66.25 m/s
Rounding to two significant figures, Δp = 800 kg m/s and Δv = 66 m/s.
Sound moves faster in warmer temperature because the particles move faster
