Choice-'a' is a slippery, misleading, ambiguous statement,
but it's less wrong than any of the other choices on this list.
Answer:
1742.24106 revolutions per day
Explanation:
v = Velocity
d = Diameter = 1.1 km
r = Radius = 
g = Acceleration due to gravity = 9.81 m/s²
g = 0.9 g
The centrifugal force will balance the gravitational force
The rotation speed is 1742.24106 revolutions per day
Answer:
Resistance is a measure of the opposite to current flow in an electrical circuit. Resistance is measured in ohms.

Answer:
Wiping cloth
Explanation:
When the wiping cloth is used to “clean” another surface, it will contaminate it with the bacteria. To avoid bacterial growth on the wiping cloth, a wet wiping cloth must be stored in a proper sanitizing solution between uses. Provide Proper Concentration of. Sanitizing Solution for Wiping Cloths.
wiping cloth cannot be used on a surface where raw meat was cleaned, utensils, plates and other kitchen eating accessories because of it's ability to contact germs and bacteria.
Answer:
166 kg *m/s
44 N upward
39 m/s east
Explanation:
The short answer: If it has direction, it's a vector.
The long answer:
Vectors, unlike scalars, have direction. The first one, 166 kg*m/s is momentum, since momentum is velocity*mass, and velocity is a vector, momentum must be a vector.
44 Newtons is a vector since it has direction, in this case, upward. Force is acceleration*mass, and since acceleration is a vector, force must be a vector.
39 m/s is velocity, velocity has a direction, therefore it's a vector.
13.7 grams is mass since mass doesn't change with direction, it's a scalar, the opposite of a vector.
86 miles per hour has speed, but speed has no direction, therefore it's a scalar.
12 meters is distance, distance has no direction, therefore it's a scalar.
