1. A 10 kg box rests on a frictionless surface. A horizontal force of 20 N is applied to the box. What is the box's acceleration?
- A. 0.5 m/s²
- B. 1 m/s²
- C. 2 m/s²
- D. 10 m/s²
Correct answer: B
Rationale: The acceleration of an object is given by the formula \(a = \frac{F}{m}\), where \(F\) is the net force acting on the object and \(m\) is the mass of the object. In this case, the net force acting on the box is 20 N, and the mass of the box is 10 kg. Plugging these values into the formula, we get \(a = \frac{20}{10} = 2\) m/s².
2. How many people can participate in a volleyball game?
- A. 14
- B. 15
- C. half of a class
- D. an entire class
Correct answer: D
Rationale: Based on the extract provided, a volleyball game can involve an entire class participating. The passage mentions that with just one net and one ball, an entire class can play volleyball. While the number of participants in a volleyball game can vary, the specific reference to a whole class in the passage indicates that a significant number of people can take part. Therefore, the correct answer is 'an entire class.' Choice A, '14,' is incorrect because the passage explicitly mentions that an entire class can participate, which typically involves more than 14 individuals. Choice B, '15,' is incorrect as it does not account for the flexibility of the number of participants in a volleyball game as stated in the passage. Choice C, 'half of a class,' is incorrect as the passage clearly states that an entire class can participate, not just half.
3. Which muscular tube carries urine from the kidneys to the bladder?
- A. Nephron
- B. Ureter
- C. Urethra
- D. Glomerulus
Correct answer: B
Rationale: The correct answer is B: Ureter. The ureter is the muscular tube that carries urine from the kidneys to the bladder. The nephron is the functional unit of the kidney responsible for filtering blood and producing urine. The urethra is the tube that carries urine from the bladder out of the body. The glomerulus is a network of capillaries in the nephron where filtration of blood occurs.
4. What is 0.5 liters in milliliters?
- A. 50 ml
- B. 500 ml
- C. 5 ml
- D. 0.5 ml
Correct answer: B
Rationale: 0.5 liters is equivalent to 500 milliliters. To convert liters to milliliters, you multiply by 1000 since 1 liter equals 1000 milliliters. Therefore, the correct answer is 500 ml (0.5 * 1000 = 500). Choices A, C, and D are incorrect because they do not correctly convert 0.5 liters to milliliters.
5. What is the difference between heat and temperature?
- A. They are the same thing.
- B. Heat is a form of energy, while temperature measures the average kinetic energy of particles.
- C. Heat flows from cold to hot, while temperature flows from hot to cold.
- D. Heat is measured in Celsius, while temperature is measured in Joules.
Correct answer: B
Rationale: Heat and temperature are distinct concepts. Heat is a form of energy that transfers from a higher temperature object to a lower temperature object, while temperature represents the average kinetic energy of particles in a substance. Heat is quantified in units like Joules or calories, whereas temperature is typically gauged in degrees Celsius or Fahrenheit. Therefore, choice B correctly distinguishes between heat and temperature, making it the correct answer. Choices A, C, and D are incorrect because they do not accurately define the difference between heat and temperature. Choice A erroneously suggests they are the same, choice C confuses the direction of heat and temperature flow, and choice D provides inaccurate units for measuring heat and temperature.
