Find the magnitude of the angular momentum of the second hand on a clock about an axis through the center of the clock face. Ass

ume the clock hand has a length of 15.0 cm and a mass of 6.00 g. Consider the second hand to be a slender rod rotating with constant angular velocity about one end. (Express your answer in the form: "1.23e-4 kg*m^2/s'.)

Answer:

L=4.711×10^{-6}Kgm^2/sec

Explanation:

we have given mass m=6 gram =0.006 kg

length =15 cm =0.15 m

moment of inertia for the clock hand is given by

I=\frac{ml^2}{3}

I=\frac{0.006\times .15^2}{3}=4.5\times 10^{-5}

angular velocity \omega =\frac{2\times \pi}{60}=0.1047 rad/sec

we know that angular momentum is given by

L=Iω

L=4.5×10^{-5}×0.1047

L=4.711×10^{-6}Kgm^2/sec

Answer:

L = 4.711 *10^{-6} kg m2/s

Explanation:

i =\frac{ml^3}{3}

= \frac{0.00*.15^2}{3}

   =4.5*10^-5

angular velocity

\omega = \frac{2\pi}{60}

             = 0.1047 rad/s

the angular momentum,

L = I\omega

L = 4.5*10^{-5}* 0.1047 rad/s

L = 4.711 *10^{-6} kg m2/s

What is a major contributor of greenhouse gases in the atmosphere?
ASHA 777 [7]

Answer:

a. burning of fossil fuel

Explanation:

Greenhouse effect is the trapping of the sun infrared rays in the outermost layer of the earths atmosphere due to the accumulation of some harmful gasses. This gases depletes the ozone layer

The major contributor of greenhouse gases is the burning of fossil fuels. Carbon dioxides are released into the atmosphere and leads to global warming and climatic changes per time

Do you think an observer on another planet in the solar system might see eclipses
artcher [175]

Answer:

Yes

Explanation:

Eclipses: Eclipses are also known as game of shadows where one object comes between the star(light source) and another object in a straight line such that the shadow of one object falls on other object. This can occur when the apparent size of the star and the object is almost same.

Talking about the Earth, the geometry is such that the Moon and the Sun are of same apparent size as seen from the Earth. Thus Lunar and Solar eclipse can be seen from the Earth. If we were to go on any other planet the same phenomenon can be seen provided the apparent size of moon and the Sun from that planet is same.

We have seen and recorded many such eclipses on Jupiter. These are from the perspective of Earth. When the moons of Jupiter comes exactly between the Sun and Jupiter the shadow of moon will fall on Jupiter. The places where the shadow falls, one will see a solar eclipse.

what are the three types of solenoids, which one is the most common, and which one is used in pinball machines?​
amm1812

Answer:

The types of solenoids are: AC Laminated Solenoid , DC Solenoid , Linear Solenoid ,and Rotary Solenoid.

Explanation:

  • The main purpose of solenoid is to generate the controlled magnetic field that can be used in many forms.
  • The most common use of solenoid is done in the pinball game.
  • The Flipper solenoid that uses the two coil are used in the mechanism of pinball machines.
  • One coil of the solenoid is supplied with high electric current where as other one has the weak current flowing through it.
