2 wheels force is put on the back gear to push a larger gear on front . when pedalling on flat force should be applied on middle to smaller size. However when bike reached a terminal force it rider will move to smaller gear and go faster. If bike is going down hill the force of gravity will mean rider can manage the smallest gear as in fastest speed as Force = Mass × Velocity and the impact of gravity means less force is required as the weight of the bike and rider However the opposite it through for uphill as the rider is going against gravity ..weight and gravity will mean the rider will need to go to the larger gear the slower speed.
There are other factors as in wind and slip stream and type of pedals to maximise the force.
The correct answer to your question and how to solve it is
The relation between wavelength (λ)and the frequency of electromagnetic oscillation (f) is described by the following expression: λ=c/f, where c–is the speed of light in vacuum = 3*10^8 m/s
Derive f from above: f = c/λ.How to Calculate: λ=890nm = 890*10^-9m = 8.9*10^-7m
f =3*10^8m/s Divided by 8.9*10^-7m = 0.34*10^15 s-1=3.4*10^14 s-1
So your Answer is: The frequency of radiation of wavelength 890 nm is 3.4*10^14s-1
The formation ice sheets cause the Earth's surface to sink so much that when the ice melts, the crust and mantle does not rebound.
Explanation:
The above-mentioned statement is the only false statement
During the Ice ages, large continental parts were covered under thick ice sheets. This imposed a superincumbent additional load on the Earth's crust.
Isostasy refers to the balance that exists between parts of Earth's mantle and crust. Isostatic adjustments are a common phenomenon. As a result of isostatic adjustments, several parts of the world have risen by as much as 900 feet as an adjustment to superincumbent load since ice ages. E.g. Parts of Scandinavian countries have witnessed these activities and also undergoing this process.
Answer: Solids
Explanation: Solids have very little movement and the particles have barely enough movement to vibrate. We can't see it but the particles are indeed vibrating. Solids have the least amount of kinetic energy which is moving energy.
