G cancels out leaving only J.
Since there is a g in the numerator and a g in the denominator, both gs can be cancelled. This leaves the J in the numerator as the final units.
When the football is on its way up, Kinetic energy is being transformed into Gravitational Potential energy.
The time taken for the object to reach to top of pile is 0.012 year.
<h3>Time of motion </h3>
The time taken for the object to reach to top of pile is calculated as follows;
time of motion = distance traveled/speed
time of motion = (1.1 x 10¹⁴ x 10³ m)/(3 x 10⁸ m/s)
where;
- speed of light = 3 x 10⁸ m/s
time of motion = 3.67 x 10⁵ sec = 0.012 year
Thus, the time taken for the object to reach to top of pile is 0.012 year.

Explanation:
local winds are considered breezes while global winds produce mostly storms
Answer:
A) SiO2 is the limiting reactant
B) Theoretical yield= 72333.3g
C) % yield =91.5%
Explanation:
SiO2(s) + 2C(s) --------------> Si(s) + 2CO(g)
n(SiO2)= 155000/60 = 2583.33 mols
n(C)= 79000/12= 3291.66 mols
a)SiO2 is the limiting reactant
According to the balanced reaction equation,
60g of SiO2 produced 28g of SiO2
155000g of SiO2 will produce 155000×28/60= 72333.3g
Therefore theoretical yield of Si= 72333.3g
% yield= 66200/72333.3×100/1 =91.5%
