B) 
Explanation:
Using the free body diagram and according to Newton's first law, we have:
A) Solving (1) for T:
B) Solving (2) for F:
<span>In this particular case, where car is moving through curvature, so it is moving in circular motion, force acting on car is centripetal force which holds car not to fly out. Centripetal force is always pointed in the middle of circle. Here frictional force has role of centripetal force. If frictional force is to weak, car would fly out of curvutare.</span>
Density is mass divided by volume, you would have to solve for the volume of the ball and rearrange the equation to density divided by volume equals mass
Almost true but not quite.
That would give you the negative of the actual acceleration.
It should be the other way around:
(final v) minus (initial v), then divide by time.
Answer: Option (a) is the correct answer.
Explanation:
Ionic compounds are the compounds whose atoms are combined together by transfer of electrons.
An ionic compound has partial positive charge on the cation and partial negative charge on anion.
For example, NaCl is an ionic compound whose atoms are arranged orderly due to the opposite charges on its atoms.
So, an ionic compound forms a neutral compound but not a neutral element.
Thus, we can conclude that ionic compounds form crystal structures.
