Explanation:
C.
Object A will require more force to be set in motion but will travel faster than object B.
2. true
Answer:
The correct option is A
Explanation:
Buoyancy can be described as the upward force that causes an object to float on water. <u>When the buoyant force of a liquid is greater than the weight of an object, the object will move to the surface of the liquid and float (because the buoyant force would be able to push it upwards)</u>. If the buoyant force is lesser than the weight of the object, the object will sink (because the buoyant force would not be able to push the object upwards). And when the buoyant force and weight of an object cancel out, the object would be suspended at the depth that this occurs.
Thus, from the explanation above, it can be deduced that for an object to float, buoyant force must be greater than weight of the object. Thus, the correct option is A.
Atomic number is the number of protons in an element. Mass number is the sum of both protons and neutrons. Thus, if you subtract 34 from 76 you’ll get the number of neutrons in said element.
76 - 34 = 42 neutrons
