Explanation:
it carries things from one place to another
According to the United Nations, there are <em>54 </em>countries in Africa today (late 2018).
A. The object is made of stone or metal, which always sink.
B. The force of gravity is stronger than the buoyant force.
C. The buoyant force is stronger than the force of gravity.
D. The mass of the item is greater than its gravity
The answer is C
Answer:
2.9 E14 Hz
Explanation:
As we know by Einstein's equation that energy incident on the photo sensitive surface will be used by the surface to eject electron out of the surface with some kinetic energy.
This is given by

now the threshold frequency is the minimum frequency of the incident photons due to which electrons are ejected out with minimum kinetic energy or least kinetic energy.
So here when KE = 0 in the graph then corresponding to that position the frequency will be given as threshold frequency
so here from graph when KE = 0

Your answer is C. Unbalanced
unbalanced forces change the direction and speed of objects, therefore it would change the constant speed of an object in motion.
Hope this helps u!
