Question 1 of 5

What is the relationship between mass and weight on Earth's surface?

Correct Answer: C

Rationale: The correct answer is C: Weight is greater than mass. Mass is a measure of the amount of matter in an object, while weight is the force of gravity acting on that object. On Earth's surface, weight is greater than mass because gravity pulls objects towards the center of the Earth, resulting in a force that we perceive as weight. Choice A is incorrect because mass and weight are not equal; weight is a force, while mass is a measure of the amount of matter. Choice B is incorrect because mass is not greater than weight; weight is the force exerted due to gravity. Choice D is incorrect as mass and weight are related; weight is dependent on mass and the gravitational force acting on the object.

Question 2 of 5

Which of the following factors can contribute to erectile dysfunction in males?

Correct Answer: D

Rationale: Erectile dysfunction can be caused by various factors, including diabetes, cardiovascular disease, and neurological disorders. These conditions can impact blood flow, nerve function, and hormone levels, all crucial for achieving and maintaining an erection. Diabetes can lead to nerve damage and affect blood circulation. Cardiovascular disease can restrict blood flow to the penis. Neurological disorders can interfere with the transmission of nerve signals between the brain and the reproductive organs. Therefore, all the factors mentioned in options A, B, and C can contribute to erectile dysfunction in males.

Question 3 of 5

Which of the following is the main organ responsible for storing energy?

Correct Answer: D

Rationale: Adipose tissue, commonly known as body fat, is the main organ responsible for storing energy in the form of triglycerides. It serves as a reserve of energy that can be utilized when needed. The liver primarily regulates glucose levels and stores glycogen for short-term energy needs but is not the main organ for long-term energy storage. The heart's main function is to pump blood throughout the body and is not involved in energy storage. The kidneys are essential for filtering blood and maintaining fluid balance but are not responsible for storing energy.

Question 4 of 5

What property of a wave determines its pitch in sound waves?

Correct Answer: B

Rationale: The pitch of a sound wave is determined by its frequency. Frequency is the number of cycles of a wave that occur in a given time period. Higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches. Amplitude refers to the intensity or loudness of a sound wave, wavelength is the distance between two consecutive points in a wave, and speed is the rate at which a wave travels through a medium. Therefore, in sound waves, it is the frequency that primarily determines the pitch, making option B the correct answer.

Question 5 of 5

Which property of matter remains constant regardless of changes in gravity?

Correct Answer: A

Rationale: Mass is a measure of the amount of matter in an object and remains constant regardless of changes in gravity. Weight, on the other hand, is the force of gravity acting on an object and can vary depending on the strength of gravity. Volume is the amount of space an object occupies, and density is the mass per unit volume of a substance, both of which can change with changes in gravity. Therefore, mass is the property that remains the same regardless of variations in gravitational force. Choice B, Weight, changes with gravity as it is a force dependent on gravity. Choices C and D, Volume and Density, can be affected by changes in gravity as they are related to the space an object occupies and the mass per unit volume, respectively.
