Answer:
1 astronomical unit is the average distance from the Earth to the Sun; approximately 150 million km. At its closest point, Saturn is 9 AU, and then at its most distant point, it's 10.1 AU. Saturn's average distance from the Sun is 9.6 AU. We have written many articles about Saturn for Universe Today.
Explanation:
<em>It is a series circuit.</em>
Answer:
Explanation:
Given
velocity of driver 
=25 m/s w.r.t ground towards north
driver observes that rain is making an angle of 
with vertical
While returning 
=25 m/s w.r.t. ground towards south
suppose 
=velocity of rain drop relative car while car is going towards north
=velocity of rain drop relative car while car is going towards south
z=vector sum of 
Now from graph
therefore magnitude of z is given by
Thus rain drops make an angle of w.r.t to ground
When firing straight up:
v^2 = u^2 - 2gh, where v = final velocity = 0, u = initial velocity, g = gravitational acceleration, h = maximum height attained.
Then,
0 = u^2 - 2gh
u = Sqrt (2gh) ---- (1)
When firing at 45°,
Initial velocity, U = u Sin 45 = Sqrt (2gh)·Sin 45
Maximum height, H = U^2*(Sin Ф)^2/2g
substituting;
H = [Sqrt (2gh)·Sin 45]^2*(Sin 45)^2]/2g
H = [2gh*(Sin 45)^2*(Sin 45)^2]/2g
H = [h*(Sin 45)^4] = h/4
Therefore, maximum height when the gun fires at 45° is a quarter of maximum height when the gun fires vertically up.
Eustress is a positive stress while distress is a negative stress.
