[Error 209] Answer could not be seen please reload.
The components are at a right angle so the resultant is R^2 = 4.50^2 + 9.80^2 R = 10.78 or 10.8
Hope this helps!!

Answer:
c, its axis is tilted
maybe
As it works its way around the sun, its tilted axis exposes different parts of earth.
C would be it because the roation of Earth on its axis doesn't have anything to do with the exposer of the revolution on its axis
Answer:
20.05 seconds
Explanation:
Given that:
v² = u² + 2as
v = final velocity
u = initial velocity
a = acceleration
s = distance
a = negative acceleration = - 0.43
s = distance = 86.5
v = 0
0 - 2(0.43)(86.5) = u²
74.39 = v²
U = sqrt(74.39)
U = 8.6249
From ;
t = Time in seconds
t = (v - u) / a
t = (0 - 8.6249) / - 0.43
t = 20.057
Explanation:
distance covered in the first part of journey : 120×14 = 1680km
distance covered in second part of journey :
90×10 = 900 km
total distance traveled : 1680+900 = 2580km.
total time taken to complete the journey : 14+10= 24 hrs.
therefore, the average speed of the journey = 2580km/24hr = 107.5 km/h.
hope this helps you.
