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?

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

the answers are a and c

the answer is c. altitude. hope this ! #brainiac

i'd have to say the answer is probable the second option "the geosphere interacting with the atmosphere"
