Answer:
pressure of solid depends on:
1/magnitude of the force
2/contact area
pressure in solid depends on:
1/depth inside the fluid.
2/density of the fluid.
3/Acceleration due to gravity.
Explanation:
1/magnitude of the force:the pressure is directly proportional to the magnitude of the force(thrust). The larger the force, the higher is the magnitude of pressure on the surface.
2/Contact area: the pressure is inversely proportional to the surface area of contact. The larger the contact area, lower is the magnitude of the pressure.
You don't need to do any calculations, you are already given that n=1.5
n is index of refraction. it's 1.5
Explanation:
It is given that,
Average power per unit mass generated by Lance, 
(a) Distance to cover race, 
Average speed of the person, v = 11 m/s
If t is the time taken to cover the race.
t = 14545.46 s
Let W is the work done. The relation between the work done and the power is given by :
W = 7090911.75 J
(b) Since, 
So, in 7090911.75 J, 
W = 1694.01 J
Hence, this is the required solution.
