5 Select the correct answer. A bicycle traveled 150 meters west from point A to point B. Then it took the same route and came ba

ck to point A. It took a total of 2 minutes for the bicycle to return to point A. What is the average speed and average velocity of the bicycle? A. The average speed is 2.5 meters/second, and the average velocity is 2.5 meters/second east. B. The average speed is 0 meters/second, and the average velocity is 2.5 meters/second east. C. The average speed and average velocity are both 0 meters/second. D. The average speed is 2.5 meters/second, and the average velocity is 0 meters/second.

D. The average speed is 2.5 m/s and the average velocity of the bicycle is 0 m/s east.

<h3>What is average speed?</h3>

The average speed of an object is the ratio of total distance to total time of motion of the object.

average speed = total distance traveled / total time taken

average speed = (150 m + 150 m) / (2 mins x 60s/min)

average speed = (300 m) / (120 s)

average speed = 2.5 m/s

<h3>What is average velocity?</h3>

The average velocity of an object is the ratio of change in displacement to change in time of motion.

v = Δx/t

v = (150 m - 150 m) / (120 s)

v = 0 m/s

Thus, the average speed is 2.5 m/s and the average velocity of the bicycle is 0 m/s east.

A map of eastern North America, showing the pH of rainfall in the various states, indicates that the pH of rain in New York Stat
pogonyaev

4.22

Explanation:

The most acidic rainfall in New York State will have pH of 4.22 whereas the least acidic will be that of 4.40.

The pH scale expresses the acidity or alkalinity of aqueous solutions.

  • The pH scale ranges from 1 to 4
  • An acidic solution will have a pH value less than 7

We have given a range of values between 4.22 to 4.40

  This implies that the pH values of rainfall in this region falls between these extremes.

   The least value 4.22 is the most acidic

    The value 4.4 is the the least acidic

The lower the pH value, the more acidic a solution is.

a net force of 1,800 N is applied to a boat causing it to accelerate at 1.5 m/s^2. what is the mass of the boat?
Xelga [282]

Answer:

<h3>The answer is 1200 kg</h3>

Explanation:

The mass of an object can be found by using the formula

m =  \frac{f}{a}  \\

f is the force

a is the acceleration

From the question we have

m =  \frac{1800}{1.5}  \\

We have the final answer as

<h3>1200 kg</h3>

Hope this helps you

DENIUS [597]
The function of the crankshaft is to convert the up-and-dwon motion of the piston into rotary motion that can be used to power the vehicle.

I attache an image of a crankshaft.

The pistons are connected to the crank pins ans when the pistons move up an down the crankshaft rotate, and so the recoprating movement of the pistons is converted into rotary motion.
