Pedro is planning to model how changes in weather affect evaporation from lakes. For his second experiment, he wants to test how

winds affect the evaporation rate. He places one beaker with 300 mL of water in an area away from any fans, and he places another beaker with 300 mL of water near a small fan.
What is the dependent variable in Pedro's experiment?

A. Volume of water
B. Evaporation rate
C. Temperature
D. Movement of air

In California the pacific plate slides past the North American plate. If the pacific plate is moving at a speed of 5 centimeters
RUDIKE [14]

Answer:

2000years

Explanation:

We will either convert the distance to centimeters or speed to meters/second.

Converting distance to centimeters: 100 meters= 100*100centimeters =10000centimeters.

time=distance/speed

t=10000/5=2000 years

A car is traveling at a velocity of 22 m/s when the driver puts on the brakes
Brums [2.3K]

The car’s velocity at the end of this distance is <em>18.17 m/s.</em>

Given the following data:

  • Initial velocity, U = 22 m/s
  • Deceleration, d = 1.4 m/s^2
  • Distance, S = 110 meters

To find the car’s velocity at the end of this distance, we would use the third equation of motion;

Mathematically, the third equation of motion is calculated by using the formula;

V^2 = U^2 + 2dS

Substituting the values into the formula, we have;

V^2 = 22 + 2(1.4)(110)\\\\V^2 = 22 + 308\\\\V^2 = 330\\\\V^2 = \sqrt{330}

<em>Final velocity, V = 18.17 m/s</em>

Therefore, the car’s velocity at the end of this distance is <em>18.17 m/s.</em>
