Answer:
4. The pressure decreases and the temperature increases.
Explanation:
PV = nRT
Rearrange:
V/R = nT/P
V is constant, so:
k = nT/P
kP = nT
n is increasing.
If P decreases, T must also decrease.
By using vector
a. the distance traveled is 12 kilometres
b. the resultant displacement is (7 i + 5 j) kilometres
We need to know about vectors to solve this problem. Vector has magnitude and also direction. Displacement is included in vector. It can be written as
s = sx i + sy j + sz k
where s is displacement, sx is displacement on x-axis, sy is displacement on y-axis and sz us displacement on z-axis.
From the question above, we know that
east = positive x
south = negative y
west = negative x
north = positive y
s1 = 7 j
s2 = 5 j
The distance traveled is
s = s1 + s2
s = 7 + 5
s = 12 kilometres
The resultant displacement is
s = s1 + s2
s = 7 i + 5 j
s = (7 i + 5 j) kilometres

Answer:
Saturn is actually far away from our star (The Sun) it would take more time and it's also consider a rocky planet. Staurn in the rocky area meaning that it would travel slow as 29.46 years to around the Sun just like Jupiter,Uranus,and Pluto,but it's not consider a planet but a floating rock.
