why does a ball in a liquid move at a constant speed, although it is affected by forces
since after certain time, the buoyant force becomes equal to the weight of the ball and the ball moves with the terminal velocity

A small ball is put into a cone and made to move at constant
speed v in a horizontal circle of constant radius r. (See figure
below.) (a) What is the ball’s centripetal acceleration? (b) What
is its tangential acceleration? (c) What force can counteract the
force of gravity so that the ball keeps moving in a horizontal
circle? (d) Use these insights to determine the height h the ball
is circling above the bottom of the cone. [Hint: This...
If you move at the speed of light, how does a light beam move relative to you? Why?
1) If Olaf catches the ball, with what speed vf do Olaf and the ball move afterward? Express your answer numerically in centimeters per second. 2) If the ball hits Olaf and bounces off his chest horizontally at 7.70 m/s in the opposite direction, what is his speed vf after the collision? Express your answer numerically in centimeters per second.
Why does toluene and ethylene glycol display liquid-liquid separation? Why does liquid-liquid separation occur and deviate from ideal liquid-vapor equilibrium?
Bonus: A ball rolls at constant speed It reaches the end of a table 1.4m high How far away from the edge of the table does the ball land? 1
At what speed would a 45.9g golf ball need to move to have a de Broglie wavelength of 100. nm?
Liquid-liquid extraction lab questions 1. Why does the m-nitroaniline dissolve in acid? 2. Why does the benzoic acid dissolve in base? 3. Why does the naphthalene remain in the organic layer? Please answer in details, thank u!
A. When a ball rolls down an incline, it gains speed but its acceleration remains constant. is this true? Explain. B. What does it mean to say Σ F = 0 for an object in equilibrium?
I swing a ball around my head at constant speed in a circle with circumference 3 m. What is the work done on the ball by the 10 N tension force in the string during one revolution of the ball? A.30 J B.20 J C.10 J D.0 J Why? I need help understanding this question. Should I use Krot=1/2Iw^2 equation???
1. A jet plane has a takeoff speed of ? = 75 m/s and can move along the runway at an average acceleration of 1.3 m/s2. If the length of the runway is 2.5 km, will the plane be able to use this runway safely? Defend your answer. 2. A person takes a trip, driving with a constant speed of 89.5 km/h, except for a 22.0 min rest stop. If the person’s average speed is 77.8 km/h, (a) how much...
