9) Who was right about the atom, Bohr or Schrodinger?
Answers
Answer: Schrodinger
Explanation: because Schrodinger used mathematical equations to describe the likelihood of finding an electron in a certain position. This atomic model is known as the quantum mechanical model of the atom.
Schrodinger because Bohr's model was not completely correct, but it has many features that are approximately correct and it is sufficient for much of our discussion.
Anand gets into an elevator and travels 50 m straight up in a time of 5 s. He then travels in the opposite direction, straight down, for 70 m in a time of 6 s. What is his average speed and velocity, respectively, over the 11 s period?
A. 10.9 m/s, 1.82 m/s
B. 10.9 m/s, −1.82 m/s
C. 21.8 m/s, 10.9 m/s
D. −10.9 m/s, 5.2 m/s
Answers
Answer:
10.9 m/s, −1.82 m/s
Explanation:
We have,
Anand gets into an elevator and travels 50 m straight up in a time of 5 s. He then travels in the opposite direction, straight down, for 70 m in a time of 6 s.
Total time of journey is 11 seconds.
Total distance is 50 m + 70 m = 120 m
Total displacement is 50 m - 70 m = -20 m
Average speed, [tex]s=\dfrac{120\ m}{11\ s}=10.9\ m/s[/tex]
Average velocity, [tex]v=\dfrac{-20\ m}{11\ s}=-1.82 \ m/s[/tex]
So, the correct option is (b) 10.9 m/s, −1.82 m/s.

D. 1st Quarter and 3rd Quarter
Answers
The phases where surfer’s most likely benefit include D. 1st Quarter and 3rd Quarter.
Surfers will benefit include during the 1st Quarter and 3rd Quarter because there's tidal change. Tidal change is when coastal areas experience two low and high tides.
The benefit of surfing during this period is that it helps jack the waves. Waves transmit energy and this is important to surfers.

You are a traffic accident investigator. You have arrived at the scene of an accident. Two cars of equal mass (1,000 kg each) were involved in a rear-end accident at a stop sign. Here is what you know: Car 1 approached the intersection from the top of a 25-meter hill. Car 2 was on a flat stretch of road directly in front of Car 1. At the bottom of the hill, Car 1 was going 20 m/s; Car 2 was going 30 m/s before it stopped at the stop sign. There were no skid marks left by Car 2. The collision occurred at the stop sign, where Car 2 had stopped. After the collision, both cars were moving together in the same direction at 10 m/s before slowly rolling to a stop. You must now push Car 2, using 800 N of force, 10 meters off to the side of the road so no one else gets hurt.
1. What was the potential energy of Car 1 at the top of the hill? (3 points)
2. What was the kinetic energy of each car before braking? (4 points)
3. A. How much energy did Car 1 lose from the top to the bottom of the hill? (3 points)
B. Where do you suppose that energy went? (2 points)
4. How much work was done to bring Car 2 to a stop? (4 points)
5. If Car 2 came to a stop in 15 seconds, how much power (in watts) did it take to stop Car 2 at the stop sign by applying force to the brakes? (3 points)
6. What is the final combined momentum of the cars right after the accident? (6 points)
7. Assuming that there are no other nonconservative forces involved, what impulse was given to each car during the collision? (6 points)
A. Car 1 (3 points)
B. Car 2 (3 points)
8. How much energy did Car 1 lose in the collision? (3 points)
9. How much energy did Car 2 gain in the collision? (3 points)
10. Which of the two laws covered in this unit - Law of Conservation of Momentum or Law of Conservation of Energy - is obeyed in this problem? Explain your reasoning. (5 points)
11. How much work did it take to move Car 2 off to the side of the road? (3 points)
12. If it took you 40 seconds to move Car 2 off the road, how much power did you expend? (3 points)
13. Which simple machine does a car have that helped you move Car 2? Explain. (2 points)

What is the resistance of a 6.0 m long gold wire (ρgold = 5.6 x 10 -8 Ω-m) whose cross-sectional area is 5x10 -7m 2 ? (Please show some work)
Answers
Answer:
R =0.672 ohms
Explanation:
We have,
Length of a gold wire is 6 m
Resistivity of gold is [tex]5.6\times 10^{-8}\ \Omega-m[/tex]
Area of cross section of the wire is [tex]5\times 10^{-7}\ m^2[/tex]
The resistance of a wire is given by the relation as follows :
[tex]R=\rho\dfrac{l}{A}\\\\R=5.6\times 10^{-8}\times \dfrac{6}{5\times 10^{-7}}\\\\R=0.672\ \Omega[/tex]
So, the resistance of the gold wire is 0.672 ohms.
When tectonic plates are strained to the point that they can no longer bend, which of the following is most likely to occur?
A. Earthquake
B. Volcanic Eruption
C. Convection Current
D. Ocean Basin Formation
Answers
When tectonic plates are strained to the point that they can no longer bend, (A) earthquake most likely to occur.
What is earthquake?An earthquake is the sudden release of energy from the earth's crust that causes the earth's surface to shake. Seismic waves, also called S waves, are consequently produced. The type and severity of an earthquake are based on the local seismic activity.
What is Volcanic Eruption?A volcanic eruption occurs when elements of the Earth, such as hot lava, rocks, and dust, erupt from a volcano in the form of an explosion. The upper portion of the volcano or one of the side branches may explode. If massive volumes of rock and volcanic ash begin to erupt, it might be dangerous. Occasionally, numerous lives are lost in these explosions.
When tectonic plates are strained to the point that they can no longer bend, in such scenario, earthquake is most likely to occur.

As SCUBA divers go deeper underwater, the pressure from the weight of all the water above them increases tremendously which compresses the gases in their blood. What happens to the volume of gas in their blood as the diver rises quickly to the surface?
A.
As a diver rises, the pressure on their body decreases which allows the volume of the gas to decrease.
B.
As a diver rises, the pressure on their body increases which allows the volume of the gas to decrease.
C.
As a diver rises, the pressure on their body decreases which allows the volume of the gas to increase.
D.
As a diver rises, the pressure on their body increases which allows the volume of the gas to increase.
Answers
Answer: A.
As a diver rises, the pressure on their body decreases which allows the volume of the gas to decrease.
Explanation:
The problem is that a diver, experiences an increased pressure of water compresses nitrogen and more of it dissolves into the body. Just as there is a natural nitrogen saturation point at the surface, there are saturation points under water. Those depend on the depth, the type of body tissue involved, and also how long a diver is exposed to the extra pressure. The deeper a diver go, the more nitrogen the body absorbs.
The problem is getting rid of the nitrogen once you ascend again. As the pressure diminishes, nitrogen starts dissolving out of the tissues of the diver's body, a process called "off-gassing." That results in tiny nitrogen bubbles that then get carried to the lungs and breathed out. However, if there is too much nitrogen and/or it is released too quickly, small bubbles can combine to form larger bubbles, and those can do damage to the body, anything from minor discomforts all the way to major problems and even death.
if 34.7 g of O2 reacts with iron to form 79.34 g of iron oxide, how much iron was used in the reaction?
A.
19.84 g
B.
44.64 g
C.
104.1 g
D.
114.04 g
Answers
Answer: B. 44.64 g
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Mass of reactants = mass of iron + mass of oxygen = mass of iron + 34.7 g
Mass of product = mass of iron oxide = 79.34 g
As Mass of reactants = Mass of product
mass of iron + 34.7 g = 79.34 g
mass of iron = 44.64 g
Thus 44.64 g of iron was used in the reaction
