The linear density of a rod of length 4 m is given by rho(x) measured in kilograms per meter, where x is measured in meters from

Elden [556K]

Answer:

50.67

Explanation:

L = 4 m

$\rho (x)=10+2\sqrt{x}$

Let the mass of small length dx is dm.

So, dm = ρ(x) dx

Integrate on both the sides within proper limits

$\int dm = \int \rho (x)dx=\int_{0}^{4}\left (10+2\sqrt{x} \right )dx$

$m = \left [ 10x+\frac{4}{3}x^{\frac{3}{2}} \right ]_{0}^{4}$

m = 40 + 32 / 3 = 152 / 3 = 50.67

Por una espira de 0.5 m2 de área circula una corriente de 5 A. Calcula la densi- dad de flujo magnético B considerando que la es

Sloan [31]

Answer:

$\beta=B=8.05\mu T$

Explanation:

The density of the magnetic flux is given by the following formula:

$\beta=\frac{\Phi_B}{A}=\frac{ABcos\theta}{A}=Bcos\theta$

The normal vector A and the vector of the magnitude of the magnetic field are perpendicular, then, the angle is zero:

The magnitude of the magnetic field is calculated by using the formula for B at a distance of x to a point in the plane of the loop:

$B=\frac{\mu_oIR^2}{2(x^2+R^2)^{3/2}}$

For x = 0 you have:

$B=\frac{\mu_oIR^2}{2R^3}=\frac{\mu_oI}{2R}$

R is the radius of the circular loop and its values is:

$R=\sqrt{\frac{A}{\pi}}=\sqrt{\frac{0.5m^2}{\pi}}=0.39m$

Then, you replace in the equation for B with mu_o = 4\pi*10^-7 T/A:

$B=\frac{(4\pi*10^{-7}T/A)(5A)}{2(0.39m)}=8.05*10^{-6}T=8.05\mu T$

and the density of the magnetic flux is

$\beta=B=8.05\mu T$

A solid steel cylinder is standing (on one of its ends) vertically on the floor. The length of the cylinder is 3.2 m and its rad

maksim [4K]

To solve this problem it is necessary to apply the concepts related to Young's Module and its respective mathematical and modular definitions. In other words, Young's Module can be expressed as

$\Upsilon = \frac{F/A}{\Delta L/L_0}$

Where,

F = Force/Weight

A = Area

$\Delta L$ = Compression

$L_0$ = Original Length

According to the values given we have to

$\Upsilon_{steel} = 200*10^9Pa$

$\Delta L = 5.6*10^{-7}m$

$L_0 = 3.2m$

$r= 0.59m \rightarrow A = \pi r^2 = \pi *0.59^2 = 1.0935m^2$

Replacing this values at our previous equation we have,

$\Upsilon = \frac{F/A}{\Delta L/L_0}$

$200*10^9 = \frac{F/1.0935}{5.6*10^{-7}/3.2}$

$F = 38272.5N$

Therefore the Weight of the object is 3.82kN

A car traveling at 22m/s is in an accident, and the 81 kg driver is brought to a stop in 1.4 s by in inflating airbag. What forc

larisa86 [58]

Here, F = m * a
F = m * v/t
Here, m = 81 Kg
v = 22 m/s
t = 1,4 s

Substitute their values,
F = 81 * 22/1.4
F = 81 * 15.71
F = 1273 N
So, Closest value from your options is 1300 N

In short, Your Answer would be Option B

Hope this helps!
