1A spring extends by 4.0 cm when a 100 g weight is hung from it. Assuming the elastic limit is not exceeded, how much will the spring extend when a 250 g weight is hung from it?
A.10.0 cm
B.8.0 cm
C.6.0 cm
D.12.5 cm
Explanation: According to Hooke's law, the extension of a spring is directly proportional to the force (or weight) applied to it. Hanging a 250 g weight is 2.5 times the force of a 100 g weight (250 / 100 = 2.5). Therefore, the extension is 4.0 cm × 2.5 = 10.0 cm.
2A block with a mass of 500 g sits on a horizontal table. If the contact area between the block and the table is 25 cm², what pressure does the block exert on the table surface? (Assume 100 g exerts a force of 1 N).
A.2000 Pa
B.500 Pa
C.200 Pa
D.5000 Pa
Explanation: A mass of 500 g corresponds to a force of 5 N. The surface area of 25 cm² is equal to 0.0025 m². Pressure is calculated as Force / Area = 5 N / 0.0025 m² = 2000 Pa (N/m²).
3An object moves along a frictionless horizontal floor at a constant speed of 2 m/s. Which statement best describes the forces acting on the object?
A.The net force acting on the object in the horizontal direction is zero.
B.A constant forward force is required to maintain the constant speed.
C.Friction is equal to the weight of the object.
D.Gravity ceases to act on the moving object.
Explanation: According to Newton's first law of motion (law of inertia), an object moving at a constant speed in a straight line on a frictionless surface experiences zero net force. The vertical forces (gravity and normal force) balance out, and no horizontal force is needed to sustain constant motion.
4A cart with a mass of 2.0 kg is pulled along a flat plane. A strobe photograph records its position every 0.1 seconds. If the distance traveled between two consecutive flashes increases uniformly by 4 cm in each 0.1 s interval, what is happening to the cart?
A.The cart is undergoing uniform acceleration.
B.The cart is moving at a constant velocity.
C.The net force on the cart is zero.
D.The cart is decelerating at a constant rate.
Explanation: Since the distance traveled in equal time intervals (0.1 s) increases by a constant amount (4 cm), the speed of the cart is increasing constantly over time. This indicates that the cart is undergoing uniform acceleration driven by a constant net force.
5A beaker containing water sits on a spring scale, registering 500 g. A solid metal block weighing 150 g in air is completely submerged in the water without touching the bottom or sides of the beaker. If the scale now reads 540 g, what is the buoyant force acting on the metal block?
A.0.4 N
B.1.5 N
C.1.1 N
D.0.5 N
Explanation: By Newton's third law, the upward buoyant force exerted by the water on the block equals the downward reaction force exerted by the block on the water. The increase in scale reading is 540 g - 500 g = 40 g. In terms of force (assuming 100 g = 1 N), 40 g corresponds to 0.4 N.
6A light ray travels from air into a rectangular glass block at an incident angle of 45°. Which of the following correctly describes the ray's path inside the glass block?
A.The angle of refraction is smaller than 45° because light bends toward the normal line.
B.The angle of refraction is larger than 45° because light bends away from the normal line.
C.The angle of refraction is exactly equal to 45° because glass does not bend light.
D.The light ray undergoes total internal reflection at the air-glass boundary.
Explanation: When light moves from an optically less dense medium (air) to a denser medium (glass), its speed decreases and it refracts toward the normal line. Consequently, the angle of refraction inside the glass is smaller than the incident angle in air.
7An object is placed at a distance equal to twice the focal length (2f) in front of a convex lens. What are the characteristics of the image formed on the screen behind the lens?
A.Real, inverted, and the same size as the object
B.Real, inverted, and magnified
C.Virtual, upright, and magnified
D.Real, inverted, and diminished
Explanation: When an object is located at 2f from a convex lens, light rays converge at 2f on the opposite side. The resulting image formed on the screen is real, inverted, and exactly the same size as the object.
8A student looks through a convex lens with a focal length of 10 cm at an object placed 5 cm in front of the lens. What type of image does the student observe?
A.An upright, magnified virtual image
B.An inverted, magnified real image
C.An inverted, diminished real image
D.An upright, diminished virtual image
Explanation: When an object is placed inside the focal length of a convex lens (d < f), the light rays diverge after passing through the lens. The back-projected rays form an upright, magnified virtual image on the same side of the lens, functioning as a magnifying glass.
9In a pinhole camera experiment, an illuminated candle of height 12 cm is placed 30 cm away from the pinhole. If the screen is placed 15 cm behind the pinhole, what is the height of the image formed on the screen?
A.6.0 cm
B.24.0 cm
C.12.0 cm
D.3.0 cm
Explanation: By similar triangles, the ratio of image height (h_i) to object height (h_o) equals the ratio of image distance (d_i) to object distance (d_o): h_i / 12 = 15 / 30. Therefore, h_i = 12 × (15 / 30) = 6.0 cm.
10A person stands 340 meters away from a tall vertical cliff and claps their hands once. If the speed of sound in air is 340 m/s, how long does it take for the person to hear the echo?
A.2.0 seconds
B.1.0 second
C.0.5 seconds
D.4.0 seconds
Explanation: The sound must travel to the cliff and reflect back to the person, covering a total round-trip distance of 340 m × 2 = 680 m. Time = Distance / Speed = 680 m / 340 m/s = 2.0 seconds.
