1. A race car moves along a circular track of radius 100m at a velocity of 25m/s. (a) What is
goldenfox [79]

Given :

A race car moves along a circular track of radius 100m at a velocity of 25m/s.

To Find :

(a) What is  the time taken to complete one lap of the circular track.

(b) What is the time taken for 10  laps.

Solution :

Circumference of circular track,

C = 2\pi r\\\\C = 2\times \pi \times 100\ m\\\\C = 628.32 \ m

a) Time taken to complete one lap is :

t= \dfrac{628.32}{25}\ s\\\\t =25.13 \ s

b) Time taken to complete 10 laps is :

t_{10} = 10\times t\\\\t_{10} = 10\times 25.13\ s\\\\t_{10} = 251.3\ s

Hence, this is the required solution.

The normal boiling point of cyclohexane is 81.0 ℃. what is the vapor pressure of cyclohexane at 81.0 ℃?
Hitman42 [59]
The boiling point is defined as the temperature at which the pressure of the vapor of the liquid is equivalent to the external atmospheric pressure surrounding the liquid. Therefore, the boiling point of the liquid is dependent on the atmospheric pressure.

Based on this, the vapor pressure of cyclohexane at 81 degrees celcius will be equal to atmospheric pressure (based on barometric readings)<span />
