Because upward buoyant force is slightly higher than gravitation force for this particular object
A
More concentrated means more collisions per unit volume, and as the volume stays the same and only concentration changes, the there are more collisions
Answer: Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion.
Answer:
The total work done will be zero.
Explanation:
Given that,
Mass = 100 kg
Force = 392 N
Velocity = 20 m/s
Distance s= 10 m
We need to calculate the work done
Using balance equation
The net force will be



The net force is zero.
Hence, The total work done will be zero by all forces on the object.
