Answer #1

Two variables are positively correlated when an increase in one variable increases the value of the other variable and also a decrease in one variable decreases the value of other variable.

On the other hand two variables are said to be negatively correlated when an increase in one variable decreases the value of the other variable and also a decrease in one variable increases the value of other variable.

We know that an increase in rate of peddling a bicycle increases the speed of bicycle and also the decrease in peddling of bicycle decreases the speed of bicycle.

Therefore the two variables here are positively correlated.

Consider 2 bicycle riders- A and B. The 2 riders, their bikes, and the wheels of their bikes all have equal mass. The radii of the wheels are both equal, however the wheels of the bike A have most of their mass at the rims while the wheels of bike B have their mass spread "evenly" over the whole area the wheel. The two cyclists travel at the same speed on level ground and approach a low hill. If they...

A steel bicycle wheel (without the rubber tire) is rotating freely with an angular speed of 11.2 rad/s. The temperature of the wheel changes from -122 to 243 °C. No net external torque acts on the wheel, and the mass of the spokes is negligible. What is the angular speed of the wheel at the higher temperature?

A steel bicycle wheel without the rubber tire is rotating freely with angular speed of 18.00 rad/s. The temperature of the wheel changes from -100.0 to 300.0 º C. No net external torque acts on the wheel and the mass of the spokes is negligible. Does the speed increase or decrease as the wheel heats up? Why? What is the final angular speed
