Answer:
decrease by a factor 10
Explanation:
The parallax angle of a close star is given by
where
p is the parallax angle
d is the distance of the star from Earth, in parsecs
From the formula we see that the parallax angle is inversely proportional to the distance.
In this problem, the distance of the star is increased by a factor 10:
d' = 10 d
so the new parallax angle would be
So, the parallax angle would decrease by a factor 10.
Answer: 10.96secs
Explanation:
According to newton's second law
Force = mass × acceleration
F = ma
F = m(v-u)/t
Cross multiplying we have
Ft = m(v-u)
t = m(v-u)/F
Given F = 2600N m = 19,000kg v = 1.5m/s u = 0m/s
Substituting this values in the formula for the time we have
t = 19000(1.5-0)/2600
t = 28,500/2600
t= 10.96secs
Answer: t = 0.878s
Explanation: Dear big brain
since your temperature decreases linearly, you can assume that your velocity should behave linearly too. Here this isn't exactly the case (cfr. formula). But there's another way to prevent endlessly boring calculus. Use the principle of interpolation. (x/v_surface + x/v_top)/2 = t.
This answer won't be exactly the same, but it's a quite good approx. You can use this eqation, hence you don't use large distances.
