False
the faster an object goes the longer it'll take to stop the object.
Answer: 33.32 s
Explanation: gravity =9.8m/s2 which means that 3.4mx9.8m/s2=33.32s
I hope this helped ! Sorry if it’s wrong :)
Answer:
36°C
Explanation:
Heat gained by the cold water = heat lost by the warm water
mCΔT = mCΔT
(1000 g) (4.184 J/g/K) (T − 20°C) = (4000 g) (4.184 J/g/K) (40°C − T)
1000 (T − 20°C) = 4000 (40°C − T)
T − 20°C = 4 (40°C − T)
T − 20°C = 160°C − 4T
5T = 180°C
T = 36°C
Centripetal acceleration ac is the acceleration experienced while in uniform circular motion. It always points toward the center of rotation. It is perpendicular to the linear velocity (tangential speed) v and has the magnitude:
Solving for v:
