Why are some fasteners double or triple threaded?

OLga [1]

<span>Fasteners are double or triple threaded with the idea of durability. People look for durability in a fastener and if they receive one with triple threaded or double threaded they will feel more safe and at ease knowing it has extra strength added.</span>

What line of code will call force with a value of 10 for mass and a value of 9.81 for acceleration?

Kaylis [27]

Line of code will call force with a value of 10 for mass and a value of 9.81 for acceleration is force(10, 9.81).

<h3 /><h3>Line of code for force and acceleration</h3>

In mechanics, acceleration refers to the rate at which an object's velocity with respect to time varies.
Acceleration is a vector quantity (in that they have magnitude and direction).
The direction of an object's acceleration is determined by the direction of the net force acting on it.
Newton's Second Law states that the combined effect of two factors determines how much an item accelerates.
The size of the net balance of all external forces acting on the object is, in accordance with the materials used to create it.
It inversely proportional to its mass, whereas the magnitude of the net resultant force is directly proportional to the net force.

def force(mass, acceleration):

force_val = mass*acceleration

return force_val

10 is assigned to mass and 9.81 is assigned to acceleration

def force(10, 9.81)

So, Line of code will call force with a value of 10 for mass and a value of 9.81 for acceleration is force(10, 9.81).

The membrane that surrounds a certain type of living cell has a surface area of 7.1 x 10-9 m2 and a thickness of 1.5 x 10-8 m. A

hoa [83]

Answer:

Q = +1.4 pC

Explanation:

The capacitance of any capacitor, by definition, is as follows:
$C = \frac{Q}{V} (1)$
Applying Gauss'Law and the definition of electric potential, it can be showed that the capacitance of a parallel-plate capacitor can be expressed as follows:
$C = \frac{\epsilon_{r}*\epsilon_{0} * A}{d} (2)$
Where εr is the dielectric constant of the material that fills the space between the plates, A is the area of one of the plates, and d, is the separation between them.
Replacing by the givens in (2) we can find the value of the capacitance C, as follows:

$C = \frac{\ 4.4*8.85e-12C2/N*m2*7.1e-9m2}{1.5e-8m} = 18.4e-12 F = 18.4 pF$

Replacing the values of C and V in (1), we can solve for Q, as follows:

$Q = C*V = 18.4e-12 F* 75.9e-3 V = 1.4e-12 C = +1.4 pC$

As the outer surface is at a higher potential that the inside surface, the charge on it must be positive, and is equal to +1.4 pC.

If a magnet could swing freely, what would happen to its north-seeking pole?

maksim [4K]

You clearly identified the pole you're talking about as the
"north-seeking" pole. Assuming your integrity and sincerity,
we would then naturally expect that pole to seek north, and
point to Earth's north magnetic pole.

I'm confident in this answer also because I have several of
these devices hanging from the ceiling of my office, and I can
attest to the fact that on most clear days, they do in fact point
toward Earth's north magnetic pole.
