9) Who was right about the atom, Bohr or Schrodinger?
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.

A negative test charge experiences a force to the right as a result of an electric field. Which is the best conclusion to draw
based on this description?
The electric field points to the left because the force on a negative charge is opposite to the direction of the field,
The electric field points to the right because the force on a negative charge is in the same direction as the field,
No conclusion can be drawn because the sign of the charge creating the field is unknown,

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
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.

An ohmmeter is a common device for measuring resistance. Using an ohmmeter, you find that a certain material has a very high resistance. This material is most likely what?
conductor
insulator
semiconductor
superconductor
Answer:
An insulator
Explanation:
Insulators have a very high resistance because the electrons of the insulator are bounded strongly with the nucleus. Hence it requires more voltage to move an electron from the valence band to the conduction band.

It is thinnest at its center and thickest at its outer edges.
It is curved outward at the center and thinnest at its outer edges.
It is curved inward in the center and thickest at its outer edge.
Answer:
Explanation:
Concave lens also called as diverging lens i.e. it diverges ray of light coming towards it.
Concave lens is thicker at the edges and thinner at the center.
Concave lens formed the virtual image of the object i.e. it cannot be trace on screen. This lens is used to treat the nearsightedness or myopia in which a person is unable to see the far object clearly.

An ant starts at −5 m and moves 10 m left, 25 m right, 30 m left, and 5 m right. If the positive x-axis is to the right, what are the final position and total displacement of the ant?
A. position: −15 m; displacement: 70 m
B. position: 5 m; displacement: 10 m
C. position: 5 m; displacement: −70 m
D. position: −15 m; displacement: −10 m
Answer: D.
position: −15 m; displacement: −10 m
Explanation:
Displacement is the distance travelled in a specific direction.
Given that an ant starts at −5 m and moves 10 m left, 25 m right, 30 m left, and 5 m right
Total displacement = -10 + 25 - 30 + 5
Total displacement = -10
And the position = -10 -5 = -15
The correct answer is therefore D.
position: −15 m; displacement: −10 m

The echo of your footsteps returns in 0.50 second. How long is the corridor in which you are walking? (Assume the speed of sound for 0°C.)
Answer: The corridor is 82.825 meters long
Explanation:
Hi, to answer this question we have to apply the next formula:
d = (t×c)/2
Where:
Speed of sound c = 331.3 m/s at 0°C
t = time = 0.5 s.
d = distance
Replacing with the values given:
d = (Δt×c)/2 = 0.5×331.3/2 = 82.825 m
The corridor is 82.825 meters long

50W of power is generated using 100J of work to move a box onto a shelf. How long did it take to move the box from the floor to the shelf?
Answer: time t = 2 seconds
Explanation:
Given that
Power P = 50W
Energy E = 100J
How long did it take to move the box from the floor to the shelf ? This implies time taken.
Power is defined as the rate at which work is done. I.e
P = W.D/t
Where work done = energy
50 = 100/t
Make t the subject of formula
t = 100/50
t = 2 second
This graph provides data on the amount of water needed to grow four different crops, each used to produce ethanol, a fuel. For each crop, the data shows how many liters of water are needed to produce one liter of ethanol fuel. Which of the following would require using the most water? *
Producing 100 L of ethanol from sugar cane
Producing 200 L of ethanol from sugar beet
Producing 300 L of ethanol from potatoes
Producing 400 L of ethanol from corn
Answer:
Producing 300 L of ethanol from potatoes
Explanation:
From the diagram, one liter of ethanol production from sugar cane requires 2000 liters of water. Hence, in order to produce 100 L of ethanol from sugar cane, 2000 x 100 = 200,000 L of water.
1000 liters of water is needed to produce 1 liter of ethanol from sugar beet. Hence, 200 x 1000 = 200,000 L of water will be needed to produce 200 liters of ethanol.
1000 liters of water is also required to produce 1 liter of ethanol from potatoes, hence, 300 x 1000 = 300,000 L of water would be required to produce 300 L of ethanol from the same material
About 500 liters of water is required to produce 1 liter of ethanol from corn, hence, 400 x 500 = 200,000 L of water would be needed to produce 400 L of ethanol from corn.
In conclusion, producing 300 L of ethanol from potatoes would require using the most water among all the options.
