there are probably multiple solutions but this is the one I came up with…
She would need to do step aerobics for 25 minutes (275 calories burned) and stretch for 15 minutes (60 calories burned) which would equal a total of 335 calories burned.
hope this helped :)
Answer:
surface tension
Step-by-step explanation:
It seems to defy the laws of physics, but a paper clip made of steel can indeed float on the water surface. The high surface tension helps the paper clip - with much higher density - float on the water.
The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. The molecules at the surface of a glass of water do not have other water molecules on all sides of them and consequently they cohere more strongly to those directly associated with them (in this case, next to and below them, but not above). It is not really true that a "skin" forms on the water surface; the stronger cohesion between the water molecules as opposed to the attraction of the water molecules to the air makes it more difficult to move an object through the surface than to move it when it is completely submersed.
Answer:
x=1 when y=2
Step-by-step explanation:
you could set up a proportion of 8/4 = 2/x.
cross multiply and you get 8x=8.
when you divide you get x=1
2
and
7

P.S. I didn't really understand the question, sorry if I'm incorrect. :/
