General Science Questions and Answers
- 1.
What is push or pull?
- A.
Weight
- B.
Angle
- C.
Tension
- D.
Force
Correct Answer
D. ForceExplanation
Push or pull refers to the action of applying force on an object. Force is a vector quantity that can cause an object to accelerate, decelerate, or change its direction of motion. In this context, weight, angle, and tension are not synonymous with push or pull. Weight refers to the force exerted by gravity on an object, angle refers to the measure of inclination between two lines or surfaces, and tension refers to the force transmitted through a string, rope, or cable. Therefore, the correct answer is force.Rate this question:

What is the quantity of matter contained in a body?
- A.
Tension
- B.
Weight
- C.
Earth's pull
- D.
Mass
Correct Answer
D. MassExplanation
Mass is the correct answer because it refers to the quantity of matter contained in a body. It is a fundamental property of an object and is independent of its location or the gravitational force acting on it. Mass can be measured in kilograms and is different from weight, which is the force exerted on an object due to gravity.Rate this question:

Which of these is the effect of the earth's gravitational pull on a body?
- A.
Fall
- B.
Gradient
- C.
Mass
- D.
Weight
Correct Answer
D. WeightExplanation
The effect of the earth's gravitational pull on a body is its weight. Weight is the force exerted by gravity on an object and is directly proportional to the mass of the object. The greater the mass of an object, the greater its weight will be. Therefore, weight is the correct answer as it represents the effect of the earth's gravitational pull on a body.Rate this question:

What is the force between two bodies in contact?
- A.
Tensional force
- B.
Gravitational force
- C.
Frictional force
- D.
Angular force
Correct Answer
C. Frictional forceExplanation
The force between two bodies in contact is called frictional force. Frictional force is a force that opposes the relative motion or tendency of motion between two surfaces in contact. When two objects are in contact, the irregularities on their surfaces interlock, causing resistance to motion. This resistance is known as frictional force.Rate this question:

How many bones are there in a human body?
- A.
260
- B.
210
- C.
200
- D.
206
Correct Answer
D. 206Explanation
There are 206 bones in the human body. The skeletal system of the human body is made up of bones, which provide support, protection, and enable movement. These bones range in size and shape, and are connected by joints. The 206 bones include the axial skeleton, which consists of the skull, vertebral column, and rib cage, as well as the appendicular skeleton, which includes the bones of the limbs and the shoulder and pelvic girdles.Rate this question:

What kind of motion occurs on a parabolic path?
- A.
Translational motion
- B.
Circular motion
- C.
Angular motion
- D.
Projectile motion
Correct Answer
D. Projectile motionExplanation
Projectile motion occurs on a parabolic path. It is the motion of an object that is launched into the air and moves under the influence of gravity. The object follows a curved trajectory, forming a parabola, due to the combination of its initial velocity and the force of gravity acting on it. This type of motion is commonly observed in activities such as throwing a ball or shooting a projectile.Rate this question:

What part of the body is essential for balancing?
- A.
Limbs
- B.
Heart
- C.
Eye
- D.
Pinnae
Correct Answer
D. PinnaeExplanation
Pinnae, also known as the outer ears, play a crucial role in balancing. They help in detecting the direction and intensity of sounds, which is essential for maintaining balance. The pinnae collect sound waves and funnel them into the ear canal, where they are processed by the inner ear. This information is then sent to the brain, which uses it to determine our position and movement in space. Therefore, the pinnae are essential for balancing.Rate this question:

What type of energy is present in a food substance?
- A.
Chemical energy
- B.
Mechanical energy
- C.
Electrical energy
- D.
Nuclear energy
Correct Answer
A. Chemical energyExplanation
The correct answer is chemical energy because food substances contain potential energy stored in the chemical bonds between their molecules. When these bonds are broken during digestion, the energy is released and can be used by the body for various functions. Mechanical energy refers to the energy of movement, electrical energy refers to the energy of electric charges, and nuclear energy refers to the energy stored in the nucleus of an atom.Rate this question:

What gas is the most abundant in air?
- A.
Chlorine
- B.
Nitrogen
- C.
Argon
- D.
Oxygen
Correct Answer
B. NitrogenExplanation
Nitrogen is the most abundant gas in air, constituting about 78% of the Earth's atmosphere. It is an essential component for many biological processes and is also used in various industries. Chlorine, argon, and oxygen are present in much smaller quantities compared to nitrogen.Rate this question:

What part of the earth is solid?
- A.
Stratosphere
- B.
Biosphere
- C.
Hydrosphere
- D.
Lithosphere
Correct Answer
D. LithosphereExplanation
The lithosphere is the solid outer layer of the Earth, consisting of the crust and the uppermost part of the mantle. It is composed of solid rocks and minerals and is responsible for supporting the continents and ocean basins. The stratosphere is a layer of the Earth's atmosphere, the biosphere refers to all living organisms on Earth, and the hydrosphere includes all water on Earth's surface. Therefore, the correct answer is the lithosphere, as it is the part of the Earth that is solid.Rate this question:
