You are going on a field trip in a school bus. A special detector placed on one of the bus's tires counts the number of rotations completed by the tire during the journey. The tire's diameter is 1 meter, and it made 8000 rotations during the trip.
How far did the bus travel?

  25,133 m or 25.1 km

Step-by-step explanation:

The circumference of the tire is ...

  C = πd

  C = π(1 m)

The distance the bus traveled is 8000 times this far, so is ...

  distance = (8000)(π m) = 8000π m

Using 3.14159 for π, we find the distance to be about

  distance = (8000)(3.14159) m ≈ 25,133 m

The bus traveled about 25,133 meters or 25.1 km.

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
