physics

1. What is the formula to calculate work?

Correct answer: a

Rationale: Work is calculated by multiplying force exerted on an object by the distance the object moves in the direction of the force.

2. Acids are generally characterized by a sour taste and the ability to:

Correct answer: B

Rationale: Acids release hydrogen ions (H+) in solution, allowing electrical conductivity

3. Which of the following is the main organ responsible for producing antibodies?

Correct answer: C

Rationale: Rationale: Antibodies are proteins produced by specialized white blood cells called B lymphocytes (B cells). These B cells mature in the bone marrow, where they undergo a process of differentiation and maturation to become plasma cells that secrete antibodies. The bone marrow is the primary site for the production of B cells and antibodies in the immune system. The thymus gland is responsible for the maturation of T lymphocytes (T cells), not antibody production. The spleen and lymph nodes play roles in filtering and trapping pathogens but are not the main organs responsible for producing antibodies.

4. Which lobe of the brain is primarily responsible for processing visual information?

Correct answer: d

Rationale: The correct answer is D: Occipital lobe. The occipital lobe is located at the back of the brain and is primarily responsible for processing visual information. This area contains the primary visual cortex, which interprets signals from the eyes and processes visual stimuli such as color, shape, and motion. The frontal lobe is more involved in higher-level thinking and decision-making processes, the parietal lobe is responsible for processing sensory information and spatial awareness, and the temporal lobe is involved in memory and auditory processing. Therefore, the occipital lobe is the main region dedicated to visual processing in the brain.

5. What is the waxy or oily substance produced by sebaceous glands that helps lubricate the skin and hair?

Correct answer: C

Rationale: The correct answer is C: Sebum. Sebum is a waxy or oily substance produced by the sebaceous glands in the skin. It helps lubricate and waterproof the skin and hair, preventing them from drying out. Keratin is a protein found in the skin, hair, and nails, providing structure and strength. Melanin is a pigment that gives color to the skin, hair, and eyes. Sweat is produced by sweat glands and helps regulate body temperature by cooling the skin through evaporation. In this question, sebum specifically refers to the substance produced by sebaceous glands, making it the correct answer.

6. Two objects with different masses collide. What happens to their momentum after the collision?

Correct answer: C

Rationale: In an isolated system (no external forces), the total momentum
