1) Andrea and Chuck are riding on a merry-go-round. Andrea rides on a horse at the outer rim of the circular platform, twice as far from the center of the circular platform as Chuck, who rides on an inner horse. When the merry-go-round is rotating at a constant angular speed, Andrea's tangential speed is which of the following?a) twice Chuck's. b) the same as Chuck's. c) half of Chuck's. d) impossible to determine.2) When the merry go round is rotating at a constant angular speed, Andrea's tangential speed is:.a) twice Chuck's. b) the same as Chuck's. c) half of Chuck's. d) impossible to determine.

Explanation:

The tangential speed of Andrea is given by :

Where

r is radius of the circular path

ω is angular speed

The merry-go-round is rotating at a constant angular speed. Let the new distance from the center of the circular platform is r'

r' = 2r

New angular speed,

New angular speed is twice that of the Chuck's speed.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

this could be newton#'s law of cooling. the cooling curve is exponential
