What is the speed of a car going v=1.000mph in SI units? Notice that you will need to change from miles to meters and from hours

to seconds. You can do each conversion separately. Use the facts that 1mile=1609m and 1hour=3600s.
Express your answer in meters per second to four significant figures.

Answer: speed = 446.4m/s

Explanation: 1000mph implies that 1000 miles / 1 hour.

But it has been given that 1mile = 1609m,

hence

1000 miles = 1000 * 1609 = 1,609,000m

And I hour = 3600s

Hence 1000mph = 1,609,000/ 3600

1000 = 446.4m/s

A student thinks that any real vibration must be damped. Is the student correct? If so, give convincing reasoning. If not, give
Stels [109]

Answer:

Yes the student is correct

Explanation:

The first law of thermodynamics states that energy can neither be created nor destroyed

The second law of thermodynamics states that the entropy (disorderliness) of an isolated system always increases

Therefore, whereby energy is not supplied to maintain the orderly oscillatory motion with constant amplitude, the amplitude of the system is bound to reduce with time that is the vibration of the system must be damped
