A circus performer on a pair of stilts exerts a pressure of 32 kPa on the ground. If the performer stands on one stilt, what pre
Agata [3.3K]

Answer:

64 kPa

Explanation:

The pressure exerted by a force on a surface is given by

p=\frac{F}{A}

where

p is the pressure

F is the force

A is the area on which the force is exerted

In this problem, let's call:

F = the weight of the performer, which is the force

A = the area of 1 stilt

At the beginning, the performer is standing on both stilts, so the area on which he exerts pressure is 2A. So the pressure is

p=\frac{F}{2A}=32 kPa (1)

Later, he stands on one stilt only. The force exerted is still the same (his weight), however, the area is now reduced to A; therefore, the new pressure is

p'=\frac{F}{A} = 2(\frac{F}{2A})=2p

which is twice the value calculated in (1); so, the new pressure is

p'=2(32)=64 kPa

A hummingbird flies 2.0 m along a straight path at a height of 5.3 m above the ground. Upon spotting a flower below, the humming
stepan [7]

To solve this problem we will apply the concepts of Pythagoras to find the net path. An easy way is to graph the path to trace the path, which resembles that of a right triangle. The information provided is equivalent to that of the two short sides of the triangle, so we will find the longest side by the Pythagorean theorem. In this way,

OC = \sqrt{2^2+2.4^2}

OC = 3.12m

Therefore the magnitude of the hummingbird’s total displacement is 3.12m
