2 Kayaks have been used for thousands of years to hunt and fish in Arctic regions.
The total volume of a particular kayak is
285 litres (which is 0.285 m). It has a mass of
75 kg. The man using it has a volume of
0.066 mº. When sitting in the kayak, half of
man's volume is inside the kayak. The density
of the human body is about 1000 kg/m.
a Calculate the density of the empty kayak.
b Calculate the mass of the kayaker.
c What is the overall density of the kayak and the kayaker when it is being paddled?

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

b is the correct answer

my teacher would say no s

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
