Answer: An example of a non-renewable would be oil.
Explanation:
All fossil fuels are nonrenewable, but not all nonrenewable energy sources are fossil fuels. Coal, crude oil, and natural gas are all considered fossil fuels
Answer:
The mechanical advantage of the system is 8
Explanation:
the mechanical advantage measures how much the system multiplies the input force to get the output.
In the given:
The input force (effort) is 20 Newton
The output force (load) is 160 Newton
This means that the mechanical advantage is:
mechanical advantage = load / effort = 160 / 20 = 8
Note that the mechanical advantage is unit-less (has no unit) since it is a ratio between two forces.
Hope this helps :)

Answer:
force = 11.33 
Explanation:
given data:
sled mass = 17.0 kg
inital velocity (U) = 4.10 m/s
elapsed time (T) 6.15 s
final velocity (V) = 0
final momentum P2 = 0
Initial momentum of sledge is
from newton second law of motion
Kgm/s^2
![F = \frac{69.7-0}{6.15}= 11.33[tex]kg-m/s^{2}](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7B69.7-0%7D%7B6.15%7D%3D%2011.33%5Btex%5Dkg-m%2Fs%5E%7B2%7D)
