Answer:
Time taken, t = 4.86 seconds
Explanation:
Given that,
Acceleration of a particular automobile, 
Initial speed of the automobile, u = 75 km/h = 20.83 m/s
Final speed of the automobile, v = 110 km/h = 30.55 m/s
We need to find the time taken to accelerate from u to v. Let t is the time taken. It can be calculate as :


t = 4.86 seconds
So, the time taken by the automobile is 4.86 seconds. Hence, this is the required solution.
Answer:
There are three types of magnets: permanent magnets, temporary magnets, and electromagnets. Permanent magnets emit a magnetic field without the need for any external source of magnetism or electrical power.
The Earth's magnetic field is believed to be generated by electric currents in the conductive iron alloys of its core, created by convection currents due to heat escaping from the core.
