We use the formula, to calculate the volume of water displaced by concrete canoe,

Here, W is the weight of concrete canoe and
is the specific weight of water and its value is
.
So,
.
Now the volume of water occupied in ultra lightweight kevlar canoe,

Here, w is weight of kevlar canoe.
So,

Thus, the volume of water displaced,
.
Hence, the volume of water displaced canoe compared to an ultra-lightweight kevlar canoe is 
Hello.
BEVs and hydrogen fuel cell vehicles are a more promising transportation technology for the future because they reduce greenhouse gas emissions as well as CO2 making it more 'green.' The second question is your opinion, in mine no, they should not be required but they should at least be considering.
Have a nice day

Answer:1.71 m/s
Explanation:
Given
mass of Susan 
Inclination 
Tension 
coefficient of Friction 
Resolving Forces Along x axis

where

since there is no movement in Y direction therefore

and 
Thus 


Work done by applied Force is equal to change to kinetic Energy




Answer:
Corpuscular theory of light
Explanation:
In optics, the corpuscular theory of light, arguably set forward by Descartes in 1637, states that light is made up of small discrete particles called "corpuscles" which travel in a straight line with a finite velocity and possess impetus. This was based on an alternate description of atomism of the time period.
