Briefly summarize how the pulleys worked with respect to changes in effort force and effort distance compared with resistance force and resistance distance what are the advantages of using pulleys what do you think would happen to the mechanical advantage if you needed a third movable pulley

Answers

Answer 1

Answer:

A pulley is a wheel with two raised edges so that a rope or a string will run along the wheel. The effort force is the one where there is a weight attached to it and enables the pulley to work while the effort distance is the distance between the pulley and the weight attached.

What is the Compact Muon Solenoid used to study?

Answers

The Compact Muon Solenoid (CMS) experiment is a particle physic detector which is used to investigate and search for the Higgs Boson, and particles that is related to dark matter. Other goals of this experiment is to for evidence such as supersymmetry and extra dimensions. It is built on a LHC or Large Hadron Collider at CERN in Switzerland and France.

Answer:

It is designed to accurately detect and study Muons.

Explanation:

Compact Muon Solenoid (CMS) is part of Large Hadron Collider (LHC) of CERN and has a use as a general purpose detector. It weighs around 14000 Tonne and built around a giant solenoid magnet. That's how it got its name: Compact Muon Solenoid (CMS). It generates 4 Tesla magnetic field that is around 100000 times the Earth's magnetic field. A yoke made up of steel is used to confine this intense field. This strong magnetic field is used to bend the path of particles.

In LHC, protons are accelerated to a very high speed in clockwise and anticlockwise direction and then collided with each other. On collision particles will be sprayed out in all directions. CMS takes the photograph and collects data during these collisions. Its main purpose is to detect Muons which are around 200 times heavier than electrons.

The Supreme Court decision in Marbury v. Madison established which of these?

Answers

Answer:

The Supreme Court decision in Marbury v. Madison established the principle of judicial review. This means that the Supreme Court has the power to declare laws or actions of the executive and legislative branches unconstitutional if they violate the Constitution. The decision was made in 1803 and is considered a landmark case in American law and politics. It established the idea that the judiciary is a coequal branch of government and has the responsibility to interpret the Constitution and ensure that the other branches of government do not exceed their constitutional authority.

Explanation:

Consider a single slit that produces a first-order minimum at 16.5° when illuminated with monochromatic light. show answer No Attempt 50% Part (a) At what angle, in degrees, is the second-order minimum?

Answers

Answer:

$\theta_2 = 34.61^0$

Explanation:

Path difference for the destructive interference of a single slit:

$D sin \theta = n \lambda$

For the first - order minimum, n = 1, and $\theta = \theta_1$

$D sin \theta_1 = \lambda$ .........(1)

For the second - order minimum, n = 2, and $\theta = \theta_2$

$D sin \theta_2 = 2 \lambda$ .........(2)

Dividing equation (2) by equation (1):

$(D sin \theta_2)/(Dsin \theta_1) = (2 \lambda)/(\lambda) \n( sin \theta_2)/(sin \theta_1) = 2 \n\theta_1 = 16.5^0\n( sin \theta_2)/(sin 16.5) = 2\nsin \theta_2 = 2 sin 16.5\nsin \theta_2 = 0.568\n\theta_2 = sin^(-1) 0.568\n\theta_2 = 34.61^0$

All of the earth's life and weather exists within the stratosphere.
a. True
b. False

Answers

The statement “All of the earth's life and weather exists within the stratosphere” is absolutely false. Thus, the correct option for this question is B.

What is Stratosphere?

Stratosphere may be defined as the second layer of the atmosphere as you go upward. It is the layer of the earth's atmosphere above the troposphere. Apart from this, it significantly extends to about 50 km above the earth's surface.

According to the context of this question, the correct and absolute answer is the troposphere. It is the first layer that is where we are able to do most of our activities. This is where we can see the formation of clouds, and the production of rain, hail, snow, and other weather phenomenon.

The troposphere is essential as it contains the Earth's weather as well as greenhouse gases to maintain the temperature on Earth. The troposphere is the lowest layer of Earth's atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.

Therefore, the statement “All of the earth's life and weather exists within the stratosphere” is absolutely false. Thus, the correct option for this question is B.

The statement “All of the earth's life and weather exists within the stratosphere” is false. The answer is letter B. The answer is the troposphere. The first layer, troposphere, is where we are able to do most of our activities. This is where we can see the formation of clouds, the production of rain, hail, snow and other weather phenomenon. Also, this layer is where the greatest amount of air pressure because most of the molecules of air are in this area. Like us, air has also mass and the pressure is brought down by the earth’s gravity causing an increase in weight exerted on you as you descend lower into the atmosphere. So, as you enter into the other layers of atmosphere above the troposphere, the air pressure starts to decrease. Below the atmosphere is the hydrosphere. This is where all liquid forms are located. And since the seawater has a greater mass than air, it has the greatest pressure.
