<u>Given that</u>
time (t) = 10 s ,
(S) = ?
We know that S = ut+ 1/2 a.t² m
since free fall and no air friction,
a = g = 9.81 m/s² ; initial velocity u= 0
S = 0 + [1/2 × 9.81 ×10²]
<em> S = 490.5 m </em>
13 is the mode because it is the number that appears most often

Answer:
10 newtons
Explanation: 10 of the 20 cancels out and the other 10 is force.
If we're talking about part c then
igneous rock + weathering and erosion = sedimentary rock
sedimentary rock + heat and pressure = metamorphic rock
magma + cooling = igneous rock
The force of gravity = GMm / r^2, where G is gravitational constant, M is mass of one object, m is mass of another object, r is distance between them.
To make gravity smaller, decrease mass or increase distance.
To make gravity bigger, increase mass or decrease distance.
