Answer:
1) Time interval Blue Car Red Car
0 - 2 s Constant Velocity Increasing Velocity
2 - 3 s Constant Velocity Constant Velocity
3 - 5 s Constant Velocity Increasing Velocity
5 - 6 s Constant Velocity Decreasing Velocity
2) For Red and Blue car y₂ = 120 v =
=
= 20 m/s
We get the same velocity for two cars because it is the average velocity of the car at the given interval of time. It is measured for initial and final position.
3) At t = 2s, the cars are the same position, and are moving at the same rate
Position - same
Velocity - same
The position-time graph shares the same spot for two cars.
Answer:
194516 sheets
Explanation:
So the area of each sheet of paper is:
A = 0.216 * 0.279 = 0.060264 square meters
For the paper sheet to make the same effect as the atmospheric pressure P, then the gravity F from the paper sheet must be
F = AP = 0.060264 * 101325 = 6106 N
Let g = 9.81 m/s2, then the mass of paper needed to generate that gravity is
m = F/g = 6106 / 9.81 = 622.4 kg
If each sheet has a mass of 0.0032 kg, then the total number of sheets to have that much mass is
622.4 / 0.0032 = 194516 sheets

Answer: Two men who helped in the development of psychology in Germany was Wilhelm Wundt, and in United States was William James.
Explanation:
Wilhelm Wundt was a German scientist, who was the first person who introduced psychology. He studied the conscious experience as a part of scientific study. It emphasis the identification of the components of the consciousness. Introspection is the process through which conscious experiences can be analyzed.
William James was a scientist, native of U.S. His purpose was to study the function of behavior all over the world. This perspective was known as functionalism. This emphasizes over the fact that how mental activities helps how organisms fit into its surrounding environment.
