The floor is exerting an upward force upon the bag in order to support the weight of the bag.
Friction force is proportional to the normal force:
f = k * N
In this case: f=27 N, k=0.23
27 N = 0.23 * N
N= 27 N : 0.23 = 117.39 N

Housing shortage is the right answer.
Rent control ordinances are a collection of laws that direct or prevent a landowner from increasing rents. While an obviously good means of ruling landlords and managing affordable accommodations, rent control is not a completely approved idea. Those who object with rent control list various reasons for their opposition. Critics of rent control hold that the regulations defend old tenants at the expense of new tenants. They contend that because the administration commands a price ceiling on the home the quality and quantity of accessible housing decays.

Final answer:
The two variables that affect current in a circuit according to Ohm's law are voltage and resistance. If voltage increases, current increases assuming resistance remains constant. Conversely, if resistance increases, current decreases.
Explanation:
According to Ohm's law, the two variables that affect the amount of current in a circuit are voltage and resistance. If the voltage in a circuit is increased, according to Ohm's law, so is the current, providing the resistance doesn't change. On the other hand, if the resistance in a circuit is increased, the current is reduced.
For instance, if we consider a simple electric circuit with a battery and a light bulb. If the voltage of the battery is increased, more current will flow, and the light bulb will shine brighter. However, if the resistance (for example by adding another light bulb in series) is increased, less current will flow, and the bulbs will be dimmer.

b. Deep Impact also released a probe to fly by the comet and record images of the collision. Determine the strength of the comet’s gravitational field at the probe’s distance of 5.0 x 103 km from the comet.
Answers
Equation: F = G*m1*m2/d^2
Where
F = 32 N
G = 6.67*10^-11 N.m^2/kg^2
m1 = 9.0*10^13kg
m2 =370 kg
d = distance that separate the center of the two objects.
d^2 = G*m1*m2 / F = 6.67*10^-11 N.m^2/kg^2 * 9.0*10^13 kg *370 kg / 32N = 69,409.69 m^2
d = √69,409.69m^2 = 263.5 m
Part B.
The gravitational field of the comet is g = G*m1/d^2
Notice that it does not depend on the mass of other objects.
Notice also that I will use a distance of 5.0 * 10^3 km, because I think that that is the number that you intended to write in the part b. If that is not the number you can put the right number instead because the solution is written step by step.
g = (6.67*10^-11 N*m^2/kg^2)*(9.0*10^13kg)/(5.0*10^3*10^3m)^2 = 2.4*10^-4 N/kg = 2.4*10^-4 m/s^2
