The problem wants to compute how long does it take for the acceleration to occur if a car travelling at 7m/s accelerates uniformally at 2.5 m/s^2 to reach a speed of 12 m/s and base on that, the time duration would be 2 seconds. I hope this would help
Distillation
Explanation:
The name of the process used to refine oil into different products is called distillation. A refinery has huge distillation columns where is separated into its different fractions.
- Distillation is a separation technique in which a mixture such as crude oil is separated into its fractions.
- The components of the mixture must have an appreciable boiling point difference.
- After distillation, oil is separated into difference components such as heavy oil, natural gas, kerosene, gasoline e.t.c.
- The liquid with the least boiling point rises up in the column first and is collected.

Answer:
maximum kientcie energy is 4 Joules.
Explanation:
When an object moves in a circular path, the tension acting on the cord is equal to the centripetal force.
Here, the cord will break if its tension exceeds 16 N and the radius of the circular path is 0.5 m. So,
.......(1)
We know that the kinetic energy of the object is given by :
Putting equation (1) in above equation as :
So, the maximum kinetic energy the object can have is 4 Joules.
