Answer:
Fc = 1.7x10^-4 N
Explanation:
Convert everything to proper units:
m = 25mg = 2.5x10^-5 kg
r = 17.6cm = 0.176m
v = 110cm/s = 1.1m/s
the formula for centripetal force is Fc = mv^2 / r
Plug everything and solve for Fc;
fc = (2.5x10^-5)(1.1^2) / 0.176
Fc = 1.7x10^-4 N
Darwin's atomic theory which states that atoms do not emit or absorb energy so far as they remain in allowable orbits or ground states.It also states that a spectra is produced when an electron moves to a lower energy level thereby releasing energy.
Constant force - stays the same throughout
Variable force - changes throughout
Answer:
D. agrarian
Explanation:
The agrarian society is a society that is strictly revolving around the agriculture and animal farming for its survival. In this type of society, the people are only engaged in producing food, be it by planting and raising certain crops or breeding domesticated animals. The main purpose of this type of society is to be able to produce enough food for the whole year, so it is a self maintaining society that consumes as much as it produces. The situation described about Ken is a reflection of this type of society.
Answer: at the same time
Explanation: in a vacuum, there isnt air, right? so there isnt gravity pushing down on the heavier object, so they will both land at the same time.
good? :)
