2.

SI unit for weight is

Kilogram (kg)
Gram (g)
Newton (N)
Centimetre (cm)

Correct Answer

A. Newton (N)

Explanation

The SI unit for weight is newton (N) because weight is a force and the newton is the unit of force in the International System of Units (SI). The newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared. Therefore, weight is measured in newtons as it represents the force exerted by an object due to gravity.

Which of the following is natural phenomenon ?

Forestry
Destruction
Flower blossoming
Forest reservation

Correct Answer

A. Flower blossoming

Explanation

Flower blossoming is a natural phenomenon because it is a process that occurs in nature without any human intervention. It is a part of the natural life cycle of plants, where flowers bloom and release pollens for reproduction. This process is influenced by factors such as sunlight, temperature, and seasonal changes, which are all natural occurrences. On the other hand, forestry, destruction, and forest reservation are all human activities or interventions in the natural environment.

which of the following is the prefix value of milli ?

0.01
0.0001
0.001
0.1

Correct Answer

A. 0.001

Explanation

The prefix value of milli is 0.001. The prefix "milli" represents one thousandth of a unit. Therefore, 0.001 is the correct answer as it represents the value of milli.

5.

When the sea breeze occur ?

Night
Day
Evening
Dusk

Correct Answer

A. Day

Explanation

Sea breeze occurs during the day. This is because during the day, the land heats up faster than the sea. As a result, the air above the land becomes warmer and rises, creating a low-pressure area. The cooler air from the sea then moves in to fill this void, creating a breeze that blows from the sea towards the land. This phenomenon is most pronounced during the afternoon when the temperature difference between the land and sea is at its peak.

................ is the distance between two points.

Correct Answer
length

Explanation
The term "length" refers to the measurement of the distance between two points. It is a scalar quantity that represents the extent of an object or the interval between two locations. In various contexts, length can be used to describe the size, dimension, or extent of an object or distance.

What is/are the instruments for measuring mass ?

Compression balance
Electronic balance
Lever balance
Double beam balance
Spring balance
Beam balance
Triple beam balance

Correct Answer(s)

A. Electronic balance
A. Lever balance
A. Double beam balance
A. Beam balance
A. Triple beam balance

Explanation

The instruments for measuring mass include electronic balance, lever balance, double beam balance, beam balance, and triple beam balance. These instruments are commonly used in laboratories and scientific settings to accurately measure the mass of objects. Electronic balance uses electronic sensors to measure the mass, while lever balance, double beam balance, beam balance, and triple beam balance use a system of levers and beams to achieve balance and determine the mass. These instruments provide precise measurements and are essential tools in various scientific experiments and research.

Definition of weight

The amount of matter in an object
The measure of the Earth's gravity force acts on an object

Correct Answer

A. The measure of the Earth's gravity force acts on an object

Explanation

The correct answer is "the measure of the Earth's gravity force acts on an object." This definition of weight refers to the force exerted on an object due to the gravitational pull of the Earth. Weight is a measure of the amount of gravitational force acting on an object, and it can vary depending on the strength of the gravitational field. It is different from mass, which is a measure of the amount of matter in an object and remains constant regardless of the gravitational field.

Effects of carbon monoxide.

Acid rain
Resulting in death
Smog
Global warming

Correct Answer

A. Resulting in death

Explanation

Carbon monoxide is a toxic gas that is released from the incomplete combustion of fossil fuels. When inhaled, it binds to hemoglobin in the blood, reducing its ability to transport oxygen. This can lead to oxygen deprivation in the body, causing tissue damage and, in severe cases, death. Therefore, the presence of carbon monoxide can result in death.
