Answer:
<h3>Newton's 2nd law states acceleration is proportional to the net force acting on an object. The net force is the vector sum of all the forces applied to the object. ... In this case the acceleration (slowing down) of the puck is proportional to the amount of friction.</h3>

I will assume you mean liquid lava, that is, magma that has been expelled by a volcano, and is flowing downhill, until it cools and solidifies as lava rock. Liquids typically have a generally inverse relationship between viscosity (resistance to flow) and temperature. That is, as the temperature increases, viscosity generally decreases (i.e., the lava gets “thinner” and “runnier”), as Gopismhas said. However, generally, in nature, lava doesn’t increase in temperature, but rather cools as it is expelled and flows downhill, and thus it is getting more and more viscous…until it solidifies.
Answer:
a) Both have same angular speed
b) Mary has larger linear speed
c) Mary has larger radial acceleration
Explanation:
a) Since Tom and Mary are both on the same merry-go-around, all points on the merry-go-around are subjected to a same angular speed. Therefore, they both have the same angular speed.
b) Linear speed, however, is the product of angular speed and their radius or rotation, aka their distance the the center of rotation. In this case Mary has a larger radius since she's sitting at the outer rim.
c) Radical acceleration is the product of angular speed squared and their radius so again, Mary would have a larger radial acceleration because of greater radius.
Answer:
Linear motion, also called rectilinear motion, is one-dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimension.
Explanation:
Rotation around a fixed axis is a special case of rotational motion. The fixed-axis hypothesis excludes the possibility of an axis changing its orientation and cannot describe such phenomena as wobbling or precession
