Archimedes' principle states that a body immersed in a fluid is subjected to an upwards force equal to the weight of the displaced fluid. This is a first condition of equilibrium. We consider that the above force, called force of buoyancy, is located in the centre of the submerged hull that we call centre of buoyancy.

A fathom is a unit of length about 6 ft long commonly used in measuring depths of water. Because a fathom is about the length of

Naddik [55]

Distance to the moon = 4× $10^{8}$ m.

1 m = 3.28 ft

Distance to the moon in ft = 4× $10^{8}$ ×3.28 ft

= 13.12 × $10^{8}$ ft

1 fathom = 6 ft

Hence, distance to the moon in fathom

= $\frac{13.2}{6}$ × $10^{8}$

≈ 2× $10^{8}$ fathom

The starter motor of a car engine draws an electric current of 16.0 A from the battery. The copper wire to the motor is 5.00 mm

Lemur [1.5K]

Answer:

The electric charge passes is 15.2 C.

Explanation:

The electric current is drawn from a battery = 16 A

The diameter of copper wire is = 5 mm

The length of copper wire is = 1.52 m

Running time of starter motor before the start of car engine = 0.95 s

Therefore, the current 16 A passes through the copper wire for 0.95 seconds.

The calculation of electric charge passes:

$Charge = i \times t \\$

$= 16 \times 0.95 \\$

$= 15.2 C$
