The correct Answer is:
To solve the question, we need to analyze both the assertion (A) and the reason (R) provided. ### Step 1: Analyze the Assertion (A) The assertion states: "The speedometer of an automobile measures the instantaneous speed of the automobile." - **Explanation**: The speedometer is a device that indicates how fast the vehicle is moving at any given moment. Instantaneous speed refers to the speed of an object at a specific point in time. Therefore, this statement is true. ### Step 2: Analyze the Reason (R) The reason states: "Average velocity is equal to total distance divided by total time taken." - **Explanation**: Average velocity is defined as the total displacement divided by the total time taken. Displacement is the shortest distance from the initial to the final position, while distance is the total path length traveled. Since the reason incorrectly states that average velocity is calculated using total distance instead of total displacement, this statement is false. ### Step 3: Conclusion - The assertion (A) is true. - The reason (R) is false. Thus, we conclude that the assertion is true, and the reason is false. ### Final Answer - Assertion (A) is true. - Reason (R) is false. ---

The speedometer of an automobile measures

Assertion : The speedometer of an automobile measure the average speed of the automobile. Reason : Average velocity is equal to total displacement per total time taken.

Total distance travelled = ............... x total time taken.

Assertion : On a curved path, average speed of a particle can never be equal to average velocity. Reason : Average speed is total distance travelled divided by total time. Whereas average velocity is, final velocity plus initial velocity divided by two.

Under what condition the magnitude of average velocity is equal to the average speed ?

The magnitude of average velocity is equal to the average speed when a particle moves:-

The reaction time for an automobile driver is 0.7 sec. If the automobile can be decelerated at 5 "m/s"^2 calculate the total distance travelled in coming to stop from an initial velocity of 8.33 m/s after a signal is observed.

An automobile of mass m accelerates from rest. If the engine supplies a constant power P, the velocity at time t is given by -

The instantaneous speed is always equal to the magnitude of instantaneous velocity. Why?

Read each statement below carefully and state with reasons, with it is true or false : (a) The magnitude of vector is always a scalar. (b) Each component of a vector is always a scalar. (c) The total path length is always equal to the magnitude of the displacement vector of a particle. (d) The average speed of a particle (defined as total path length divided by the time taken to cover the path) is greater or equal to the magnitude of average velocity of the particle over the same interval of time. (e) three vectors not lying in a plane can never add up to give a null vector.
