QUESTION: 42

A man lifts a 200 lb rock from the floor to a height 6 feet of the ground. How much work must the man perform in order to keep the object in the air?

1200 ft lb
33.3 ft lb
0 ft lb
2000 ft lb
Not enough information is provided

Answer(s): C

Explanation:

Work = Force × Distance. Because the question asks about the work performed to keep the rock above the man, the rock is not being displaced, and thus, no work is being done as displacement = 0. Work is only being done in reference to the actual displacement movement. Be careful for questions that give you meaningless information in relation to the answer.

A circuit contains a 2Ω and a 5Ω resistor, connected in parallel to each other. What is the equivalent resistance in this circuit?

7Ω
10Ω
0.7Ω
10/7Ω
5/2Ω

Answer(s): D

Explanation:

Resistors in parallel add via: 1/Req = 1/R + 1/R… 1/Req = 1/2 + 1/5 Finding a common denominator: 5/10 + 2/10 = 7/10 = 1/Req Flipping it to attain Req = 10/7Ω

QUESTION: 44

A cannon is fired at an angle of 30° above the ground, with an initial velocity of 100 m/s. How long will it take for the cannon ball to hit the ground assuming there is no air resistance?

10 seconds
20 seconds
50 seconds
100 seconds
Cannot be calculated with this information.

Answer(s): A

Explanation:

Visualize the problem as a vector, and find the y component of it: 100 m/s × sin30 = 50 m/s. This means the cannon traveled 50 meters up, and 50 meters down in the y direction. Gravity is 10 m/s2, thus it took 5 seconds to go up, and another 5 seconds to go down, totaling an air time of 10 seconds.

QUESTION: 46

Rank the following in ascending order of wavelength magnitude:
I)Gamma rays
II)X-Rays
III)Visible light IV. Radio waves

III –> I –> II –> IV
I –> II –> III –> IV
II –> I –> IV –> III
IV –> III –> II –> I
II –> I –> III –> IV

Answer(s): B

Explanation:

The energy and frequency increases from Radio waves –> Microwaves –> IR –> Visible light –> UV –> X-Rays –> Gamma rays.
But wavelength increases inversely, starting from Gamma rays (having the smallest wavelengths) to Radio waves (having the largest wavelengths)

QUESTION: 47

A wire of resistance R is about to be replaced with a different wire that is three times as long and having a radius three times as much as the original wire. What is the resistance of this new wire?

1/2
1/4
1/3
1/5
The resistance is the same in both wires.

Answer(s): C

Explanation:

The resistance formula is R = p(L/A); where p = resistivity, L = length and r = radius. Tripling the length gives 3L, whereas tripling the radius would make the area 9x as big (A = 2pi × r2). Thus, you would end up with a ratio of 3/9, which is 1/3 the resistance of the new wire.

QUESTION: 48

A manometer filled with mercury has a higher pressure on the open end, with a difference of 380 mm in the height of the fluid. What is the pressure of the gas in there?

100,000 Pa
75,000 Pa
50,000 Pa
25,000 Pa
Cannot be determined.

Answer(s): C

Explanation:

In manometers filled with mercury (Hg), the difference in height of the fluid is equivalent to the difference in pressure. There is a difference in 380 mmHg between the pressure inside and outside, which is half of the atmospheric pressure of 760 mmHg, or 1 atm. 1 atm is roughly 100,000 Pa, so the pressure inside is 50,000 Pa.

What the OAT Exam Tests and How to Pass It

The Optometry Admission Test, or OAT, serves as a critical gateway for individuals seeking to enter the field of optometry. This Test Prep certification is designed to assess the academic ability and scientific comprehension of prospective students who intend to enroll in optometry schools. Admissions committees use the results of this certification exam to evaluate whether a candidate possesses the foundational knowledge necessary to succeed in a rigorous doctoral program. By standardizing the assessment process, the OAT ensures that all applicants are measured against a consistent set of academic benchmarks, which helps schools maintain high educational standards. Achieving a strong score on this exam is a fundamental requirement for anyone aiming to pursue a professional career as an optometrist.

What the OAT Exam Covers

The OAT evaluates candidates across several distinct domains that are essential for success in optometry school. The exam includes a Survey of the Natural Sciences, which tests your grasp of biology and chemistry, alongside a Reading Comprehension section that measures your ability to analyze complex texts. Candidates must also demonstrate proficiency in Physics and Quantitative Reasoning, which requires applying mathematical principles to solve problems. Our practice questions are designed to mirror the structure of these domains, allowing you to familiarize yourself with the specific types of challenges you will encounter. By engaging with these practice questions, you can identify which areas require more focused study and which concepts you have already mastered.

The Survey of the Natural Sciences is often considered the most technically demanding portion of the exam because it requires a broad and deep understanding of multiple scientific disciplines. Candidates must recall specific biological processes and chemical reactions while also applying that knowledge to solve complex, multi-step problems. This section tests your ability to synthesize information from different areas of science, which is a skill that will be heavily utilized throughout your optometry education. Success in this area requires more than simple memorization, as you must be able to apply scientific principles to novel scenarios presented in the exam.
