SI unit of length is symbolically represented as:
-
M
-
G
-
Kg
-
S
Correct Answer
A. MExplanation
The SI unit of length is symbolically represented as "m" which stands for meter. The meter is the standard unit of length in the International System of Units (SI) and is used to measure distances. It is defined as the distance that light travels in a vacuum in 1/299,792,458 of a second.Rate this question:

500 gm= ______kilogram.
-
0.5
-
0.005
-
0.05
-
0.50
Correct Answer
A. 0.5Explanation
The question is asking for the equivalent value of 500 grams in kilograms. To convert grams to kilograms, we divide the number of grams by 1000. Therefore, 500 grams is equal to 0.5 kilograms.Rate this question:

A bike moving on a straight road is an example of____motion.
-
Linear
-
Oscillatory
-
Circular
-
Curvilinear
Correct Answer
A. LinearExplanation
A bike moving on a straight road is an example of linear motion because it follows a straight path without any change in direction. Linear motion is characterized by movement in a straight line, and in this case, the bike is not deviating from its path or moving in any other direction.Rate this question:

The quantity that can be measure is called:
-
Physical quantity
-
Measurement
-
Unit
-
Motion
Correct Answer
A. MeasurementExplanation
Measurement refers to the process of quantitatively determining the value of a physical quantity. It involves comparing the unknown quantity with a known standard unit. Therefore, measurement is the correct answer as it directly relates to the act of quantifying a physical quantity.Rate this question:

The girth of a tree can be measured by:
-
Metre scale
-
Metre rod
-
Plastic ruler
-
Measuring tape
Correct Answer
A. Measuring tapeExplanation
The girth of a tree can be measured using a measuring tape because it provides a flexible and accurate way to measure the circumference of the tree trunk. A measuring tape can easily wrap around the tree trunk and provide an accurate measurement in units such as centimeters or inches.Rate this question:

Gravitational force is a____force.
-
Non contact
-
Contact
-
Uniform
-
Periodic
Correct Answer
A. Non contactExplanation
Gravitational force is a non-contact force because it acts between two objects without any physical contact between them. It is the force of attraction between two objects with mass, and it is always present regardless of whether the objects are in direct contact or not. This force is responsible for holding planets in their orbits around the sun, and it is also what gives weight to objects on Earth.Rate this question:

Unit of speed is:
-
M
-
S
-
Kg
-
M/s
Correct Answer
A. M/sExplanation
The unit of speed is measured in meters per second (m/s). This unit represents the distance traveled in meters divided by the time taken in seconds. It is commonly used in physics and engineering to quantify the rate at which an object or person is moving.Rate this question:

The motion of a wheel in a car.
-
Linear
-
Rotatory
-
Circular
-
Zigzag
Correct Answer
A. RotatoryExplanation
The motion of a wheel in a car is best described as rotatory. When a car is in motion, the wheels rotate in a circular motion around their central axis. This rotation allows the car to move forward or backward. The term "rotatory" accurately captures the circular motion of the wheels, making it the correct answer in this context.Rate this question:

The correct relation among following is:
-
Speed= distance *time
-
Speed= distance /time
-
Speed= time /distance
-
Speed=1/( distance *time )
Correct Answer
A. Speed=1/( distance *time )Explanation
The correct relation among the given options is Speed=1/( distance *time ). This equation represents the inverse relationship between speed, distance, and time. It suggests that as the distance and time taken to cover that distance increase, the speed decreases. The equation also indicates that speed is inversely proportional to the product of distance and time, meaning that an increase in either distance or time will result in a decrease in speed.Rate this question:
