You can increase the capacitance of a capacitor by decreasing the plate spacing (A) or by increasing the area of the plates (D).
'A' and 'D' both do the job, so the correct choice is<em> (E)</em> .
Answer:
44.7 N
Explanation:
The gravitational force between the objects is given by:
where
G is the gravitational constant
m and M are the masses of the two objects
r is the distance between the centres of the two objects
In this problem, we have:
is the mass of the sphere
is the Earth's mass
is the Earth's radius, while h=310 km is the altitude of the sphere, so the distance of the sphere from Earth's centre is
Substituting into the equation, we find
Rocks,Fossils,Carbon dating

Answer:
16. c
17. d
Explanation:
16. Newton’s third law states that a force will always have an opposite but equal force as a reaction, so every force comes as a pair of action-reaction forces. For example, if you push on a book, the book also pushes on you.
17. If 1cm represents 15N, then 5cm must represent 15N*5=75N.
