Answer:
increases increases decreases
Explanation:
For an object falling from a height
Given:
Object in circular motion 25 m/s
1 second to go quarter circle
Required:
Centripetal acceleration:
Solution:
Acceleration = v2/r
Where v is the velocity and r is
the radian
Substituting the values into the
equation,
Acceleration = v2/r = (25
m/s)2/(4*pi/180) = 8952.47 m2/s2
Heat flows naturally from a warmer object (higher energy) to a cooler one (lower energy).
