Hello!
Recall the equation for gravitational force:
Fg = Force of gravity (N)
G = Gravitational constant
m1, m2 = masses of objects (kg)
r = distance between the objects' center of masses (m)
There is a DIRECT relationship between mass and gravitational force.
We are given:
If we were to double one mass and triple another, according to the equation:
Thus:
Explanation:
It is given that,
The signal to a speaker causes 0.5 amps of current,
The signal level is increased to 2.5 amps,
We need to find the gain to the nearest decibel. The decibel gain formula of the speaker is given by :
db = 13.97 db
or
db = 14 db
So, the gain pf the speaker is 14 db. Hence, this is the required solution.
The capacitor is a device that can store electrical energy. It is a two-conductor configuration. The charge on each plate of the capacitor will be 3.6 µC.
<h3>What is a capacitor?</h3>A capacitor is a device that can store electrical energy. It is a two-conductor configuration separated by an insulating medium that carries charges of equal size and opposite sign.
An electric insulator or vacuum, such as glass, paper, air, or a semi-conductor termed a dielectric, can be used as the non-conductive zone.
The given data in the problem is;
C is the capicitence of capicitor= 0. 40 µF
V is the voltage = 9. 0 V
Q is a charge on each plate of the capacitor=?µC.
The formula for the capacitor is given as;
Hence the charge on each plate of the capacitor will be 3.6 µC.
