The angular speed of an automobile engine is increased at a constant rate from 1080 rev/min to 2670 rev/min in 13.6 s. (a) What is its angular acceleration in revolutions per minute-squared

Answers

Answer 1

The angular acceleration of the automobile engine is 116.9 rev/min^2 which is increased at a constant rate from 1080 rev/min to 2670 rev/min in 13.6 s.

To find the angular acceleration of the automobile engine, we can use the formula:
Angular acceleration (α) = (Final angular speed - Initial angular speed)/time
Here, the initial angular speed (ω1) = 1080 rev/min, the final angular speed (ω2) = 2670 rev/min, and the time (t) = 13.6 s.
So, the angular acceleration (α) = (2670 rev/min - 1080 rev/min)/13.6 s = 116.9 rev/min^2
It's worth noting that acceleration is the rate of change of velocity, and velocity is the rate of change of displacement. In the case of angular motion, speed is the rate of change of angular displacement, so we can use the same concepts and formulas as we do for linear motion, but with angular quantities instead.

The preservation and promotion of indigenous languages, arts, and traditions helps to maintain and strengthen Nigerian culture, which in turn promotes a sense of national pride and identity.

2. Globalization and westernization have had a significant impact on indigenous cultures and identities in Nigeria. Many aspects of Nigerian culture, such as language, music, and dress, have been influenced by Western culture.

This has led to a loss of some indigenous cultural practices and traditions. However, there is also a growing movement to reclaim and revitalize indigenous cultures and traditions.

3. Education and the media play an important role in promoting cultural diversity and understanding in Nigeria. Education can help to teach young Nigerians about the importance of their own culture, as well as the cultures of others.
