Answer:
At 5km/hr; Hypnotist travels with a higher speed.
Explanation:
Let hypnotist be H while Raul be R.
Given the following data;
Distance H = 5km
Time H = 1 hour
Distance R = 5km
Time R = 2 hours
To find the their respective speed;
a. For H;
Speed = distance/time
Speed H = 5/1
Speed H = 5km/hr
b. For R;
Speed = distance/time
Speed R = 5/2
Speed R = 2.5 km/hr
Therefore, hypnotist travels with a higher speed.

Answer: ME= E total - E thermal
The pressure drop in pascal is 3.824*10^4 Pascals.
To find the answer, we need to know about the Poiseuille's formula.
<h3>How to find the pressure drop in pascal?</h3>
- We have the Poiseuille's formula,

- where, Q is the rate of flow, P is the pressure drop, r is the radius of the pipe, is the coefficient of viscosity (0.95Pas-s for Glycerin) and l being the length of the tube.
- By substituting values and rearranging we will get the pressure drop as,

Thus, we can conclude that, the pressure drop in pascal is 3.824*10^4.
