A group of students painted four cans, placed 500 grams of water in each can, and measured the temperature of the water as shown
inna [77]

B.The water molecules in the black can had the largest increase in average kinetic energy.

<u>Explanation:</u>

Here, black painted can absorbs more heat than the other color painted cans.

Black color absorbs all the heat and didn't reflect anything back, so it absorbs the most heat.

White color reflects all the heat, so heat absorbed by the white can is least.

When the black can absorbs heat then the water molecules in the can gets its maximum amount of kinetic energy so that the water molecules in the can collide with each other and also along with the walls of the can here, and so the average kinetic energy increases.

Which best describes a relationship among the vectors? Vectors P and Py are components of vector Px. Vectors Px and Py are compo
mafiozo [28]
If we have a vector P, then we name it's components by the axis we project it onto.

In 2D Cartesian coordinate system we have one x axis and one y axis.

Vector P can then be represented with two components: Px and Py.

Px is the component of vector P on the x axis and Py is the component of the vector P on the y axis.
