A foot is 1/3 of a yard. What part of a meter is a millimeter?

to get a flat uniform cylindrical satellite spinning at the correct rate, scientists fire 4 tangential rockets. suppose that the

Elena-2011 [213]

Answer:

The steady force required of each rocket is 31.36 N

Explanation:

Given that,

Mass of satellite = 3600 Kg

Radius = 4 m

Mass of rocket = 250 kg

Time = 5 min

Angular velocity = 32 rpm

We need to calculate the moment of inertia

Using formula of moment of inertia

$I=\dfrac{1}{2}Mr^2+4mr^2$

Where, M = mass of satellite

r = radius

m = mass of rocket

Put the value into the formula

$I=\dfrac{1}{2}\times3600\times4^2+4\times250\times4^2$

$I=44800\ kg-m^2$

We need to calculate the angular acceleration

Using formula of angular acceleration

$\alpha=\dfrac{\omega}{t}$

Where, $\omega$ = angular velocity

t = time

Put the value into the formula

$\alpha=\dfrac{2\pi\times32}{3600\times5}$

$\alpha=0.0112\ rad/s^2$

We need to calculate the steady force required of each rocket

Using formula of torque

$\tau=I\alpha$

$4rF=I\alpha$

$F=\dfrac{I\alpha}{4r}$

Put the value into the formula

$F=\dfrac{44800\times0.0112}{4\times4}$

$F=31.36\ N$

Hence, The steady force required of each rocket is 31.36 N

At what distance x from the center of the coil, on the axis of the coil, is the magnetic field half its value at the center?

Mrac [35]

Answer:

The value of x is 2.1 cm from the center of the coil.

Explanation:

Radius, R = 2.7 cm

Number of turns, N = 800

The magnetic field at the axis is half of the magnetic field at the center.

$B_{axis}=\frac{B_{center}}{2}\\\\\frac{\mu o}{4\pi}\times \frac{2 \pi I N R^2}{\left (R^2 + x^2 \right )^{\frac{3}{2}}} = 0.5\frac{\mu o}{4\pi}\times\frac{2\pi N I}{R}\\\\\frac{R^2}{(R^2 + x^2)^\frac{3}{2}} = \frac{1}{2R}\\\\4R^6 = (R^2+x^2)^3\\\\1.6 R^2 = R^2 + x^2\\\\x^2 = 0.6 \times 2.7\times 2.7 \\\\x = 2.1 cm$

According to max weber, flaunting of one’s wealth to show one’s status is called?

myrzilka [38]

Status refers to a person's prestige, social honor, or reputation in society. Weber stated that political strength become now not rooted entirely in capital fees, but additionally in a single's individual popularity. Poets or saints, for example, can own a massive impact on society, often with little monetary worth.

The German sociologist Max Weber formulated a three-component theory of stratification that defines a status group (additionally status class and status estate) as a group of humans within a society who can be differentiated by means of non-financial characteristics along with honor, prestige, ethnicity, race, and religion.

Social stratification entails society as a system of hierarchical categories. Max Weber defined stratification because the division of a society into distinct communities, that have varying assignments of “status honor” or status.
