,HESI A2 Physics Exam (Latest Update) 25 Questions
and Verified Answers| 100% correct| Grade A
1. Which of the following is a unit of power?
A. Newton (N)
B. Watt (W)
C. Volt (V)
D. Joule (J)
Explanation:
The correct answer is B. Watt (W) is the unit of power, which measures the rate of
energy transfer or the rate at which work is done.
2. What does Ohm's Law state?
A. Voltage is directly proportional to resistance.
B. Current is inversely proportional to resistance.
C. Current is directly proportional to resistance.
D. Voltage is inversely proportional to current.
Explanation:
The correct answer is C. Ohm's Law states that the current flowing through a
conductor is directly proportional to the voltage across it, provided the temperature
remains constant.
,3. Which of the following is a vector quantity?
A. Mass
B. Speed
C. Distance
D. Velocity
Explanation
The correct answer is D. Velocity is a vector quantity because it has both magnitude
and direction, unlike mass, speed, and distance.
4.What is the SI unit of force?
A. Newton (N)
B. Joule (J)
C. Watt (W)
D. Kilogram (kg)
Explanation:
The correct answer is A. Newton (N) is the SI unit of force, defined as the force
required to accelerate a mass of one kilogram by one meter per second squared.
5. Which of the following is a measure of the resistance of a material to the flow of
electric current?
A. Capacitance
B. Conductance
C. Resistance
D. Reactance
, Explanation:
The correct answer is C. Resistance is the measure of the opposition to the flow of
electric current in a material. It is measured in ohms.
6. What is the main purpose of a fuse in an electrical circuit?
A. To regulate voltage
B. To store electrical energy
C. To increase resistance
D. To protect against overcurrent
Explanation:
The correct answer is D. The main purpose of a fuse in an electrical circuit is to protect
against overcurrent by breaking the circuit when the current exceeds a certain value.
7. Which of the following best describes the concept of inertia?
A. The tendency of an object to remain at rest
B. The resistance of an object to change its state of motion
C. The gravitational force acting on an object
D. The force exerted by an object due to its acceleration
Explanation:
The correct answer is B. Inertia is the resistance of an object to change its state of
motion. It is described by Newton's First Law of Motion.
8. Which of the following is a form of potential energy?
