The gravitational force between two objects is 100 n
if the mass of each object is doubled, what is the
gravitational force between the objects at the same
distance?
a: 25 n
b: 50 n
c: 200 n
d: 0400 n

D

Explanation:

The general equation for this is

F = G*m1*m2/r^2

If the distance (r) remains the same and m1 and m2 are both doubled, then the equation becomes

F1 = G * (2m1)(2m2)/r^2

F1 = 4 [G * m1 * m2)/r^2 ]

So F1 is 4 times as large as the initial Force (F)

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
