1 answer:

4 0

The answer is : Planetesimals, protoplanets, planets. This is the order of the celestial body from earliest to latest. A protoplanet is a massive object that will eventually become a planet. They are at first formed by the accumulation of planetesimals into protoplanets, then into planets.

A disk between vertebrae in the spine is subjected to a shearing force of 600 N. Find its shear deformation, taking it to have a

Verizon [17]

Answer:

The shear deformation is $\Delta x=3.34\times10^{-6}\ m$ .

Explanation:

Given that,

Shearing force F = 600 N

Shear modulus $S = 1\times10^{9}\ N/m^2$

length = 0.700 cm

diameter = 4.00 cm

We need to find the shear deformation

Using formula of shear modulus

$S=\dfrac{Fl_{0}}{A\Delta x}$

$\Delta x=\dfrac{Fl_{0}}{(\dfrac{\pi d^2}{4})S}$

$\Delta x=\dfrac{4Fl_{0}}{\pi d^2 S}$

Put the value into the formula

$\Delta x=\dfrac{4\times600\times0.700\times10^{-2}}{3.14\times1\times10^{9}\times(4.00\times10^{-2})^2}$

$\Delta x=3.34\times10^{-6}\ m$

Hence, The shear deformation is $\Delta x=3.34\times10^{-6}\ m$ .

A circuit has an impedance of 5 ohms and a voltage of 100 volts. What is the current flow?

Ket [755]

A circuit with an impedance of 5 ohms and a voltage of 100 volts has a current flow of 20 A.

The expression of an electronic component, circuit, or system's resistance to alternating and/or direct electric current is called impedance, indicated by the letter Z. Resistance and reactance are two distinct scalar (one-dimensional) phenomena that combine to form impedance, a vector (two-dimensional) variable.

$Z^{}$ = $\frac{V}{I}$

(for a pure resistor where Z=R,preserving the form of the DC Ohm's law).

$I=\frac{V}{Z}$

$I = \frac{100}{5}$

I = 20 A

Therefore, A circuit with an impedance of 5 ohms and a voltage of 100 volts has a current flow of 20 A.

On a hypothetical scale X The ice point is 40° and steam point is 120°.

arlik [135]

Answer:

The reading of Y is -10°.

Explanation:

For scale X, the ice point is 40° and steam point is 120°.

Difference between the two extremes for scales X = 120 - 40 = 80

For scale X, the ice point and steam points are -30° and 130° respectively.

Difference between the two extremes for scales X = 130 - (-30) = 160

Comparing both scales:

One unit of scale X = x

One unit of scale Y = y

Scale X has 80 divisions while scale Y has 160

80x = 160y

x = 2y

50° in scale X = 10x + ice point in X scale

10 divisions in Y scale = 20y

Reading of Y scale = ice point of Y + 20y

= -30° + 20°

= -10°

Soccer fields vary in size. a large soccer field is 115 m long and 85 m wide. what are its dimensions in feet and inches? (assum

Irina18 [472]

The dimension of soccer field in ft is 377.315 ft long and 277.885 ft in width.

The dimension of soccer field in ft is 4527.78 in long and 3334.62 in in width.

As it is given that 1 m =3.281 ft

Therefore the length of the soccer field in ft is

115*3.281=377.315 ft

And width of the field is 85*3.281=277.885 ft

We know that 1 ft =12 in

Therefore the length of the soccer field in in is

377.315*12=4527.78 in

And width of the field is 277.885 *12=3334.62 in
