Coal is the answer to the question
Answer:
Option B. doubles
Explanation:
This can be explained by the definition of capacitance that charge on the capacitor will remain constant irrespective of the voltage applied.
This can be given as:
Q ∝ V or Q = CV
where,
Q = charge
V = Voltage
C = Capacitance
So, when V is doubled, C shoul reduce to half to main constant charge on the capacitor:
V' = 2V
C' =
Also , Energy stored in a capacitor, E is given by:
E = (1)
Now, when
V' = 2V
C' =
Using eqn (1):
E' =
Energy, E' =
E' = = 2E
Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, and is the primary interaction occurring in ionic compounds.A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Hi there!
Since the ball is directed 60° above the horizontal, we must use its HORIZONTAL component to find its displacement.
We can take the cosine to do so:
vcosθ = 28.3cos(60) = 14.15 m/s
Since the ball is in the air for 5 sec, we can use the following equation:
displacement = velocity · time (d = vt)
Plug in the values:
d = 14.15 · 5 = 70.75 m
