Answer:
FALSE
Explanation:
When object float in water then it means that weight of the object is counterbalanced by the buoyancy force.
Here as we know that buoyancy force is the weight of water displaced by the object.
So here when object is submerged into the water then the submerged part of the volume of object will displace exactly the same volume of water and that volume of water will exert upwards buoyancy force on the object.
So here this statement is not true as it says that volume of water displaced is volume above the surface of water while it must be like volume of water displaced must be equal to volume of submerged part of the object.
Answer:
Kinetic energy = 0.25 J
Explanation:
The question is "If we take container one as a reference and apply 5 grams of ink and the water moves at a speed of 10m / s, what would the kinetic energy of the solution be?"
We have,
Mass of ink, m = 5 grams = 0.005 kg
Speed of water, v = 10 m/s
We need to find the kinetic energy of the solution of water and ink. Kinetic energy is associated with the motion of an object. Its formula is given by :

So, the kinetic energy of the solution is 0.25 Joules.
