Answer:

Answer: Ionization by the alpha particle seeds the formation of clouds where the particle has passed.

The inner atmosphere of a cloud chamber is composed of an easily ionizable gas, this means that little energy is required to extract an electron from an atom. This gas is maintained in the supercooling state, so that a minimum disturbance is enough to condense it in the same way as the water is frozen.

Then, when a charged particle with enough energy interacts with this gas, it ionizes it.

This is how alpha particles are able to ionize some atoms of the gas contained inside the chamber when they cross the cloud chamber.

These ionized atoms increase the surface tension of the gas around it allowing it to immediately congregate and condense, making it easily distinguishable inside the chamber like a small cloud. In this way, it is perfectly observable the path the individual particles have traveled, simply by observing the cloud traces left in the condensed gas.

A rotating fan completes 1200 revolutions every minute. consider the tip of a blade, at a radius of 0.19 m. through what distance does the tip move in one revolution?

Answers

The tip of the fan moves through the outer side of the circle.

So it moves a distance of perimeter of circle in one revolution.

Perimeter of circle = 2 $\pi$ r, where r is the radius of circle.

In this case radius of circular motion = 0.19 meter

So perimeter of circle = 2 $\pi$ *0.19 = 0.38 $\pi$ = 1.194 m

So distance does the tip move in one revolution = 1.194 meter

Differences between gravitational and electromagnetic radiation

So far we have been emphasizing how, at a fundamental level, the generation and propagation of gravitational and electromagnetic radiation are basically quite similar. This is a major point in demystifying gravitational waves. But, on a more practical level, gravitational and electromagnetic waves are quite different: we see and use electromagnetic waves every day, while we have yet to make a confirmed direct detection of gravitational waves (which is why they seemed so mysterious in the first place).

There are two principal differences between gravity and electromagnetism, each with its own set of consequences for the nature and information content of its radiation, as described below.

Gravity is a weak force, but has only one sign of charge.
Electromagnetism is much stronger, but comes in two opposing signs of charge.
This is the most significant difference between gravity and electromagnetism, and is the main reason why we perceive these two phenomena so differently. It has several immediate consequences:Significant gravitational fields are generated by accumulating bulk concentrations of matter. Electromagnetic fields are generated by slight imbalances caused by small (often microscopic) separations of charge.Gravitational waves, similarly, are generated by the bulk motion of large masses, and will have wavelengths much longer than the objects themselves. Electromagnetic waves, meanwhile, are typically generated by small movements of charge pairs within objects, and have wavelengths much smaller than the objects themselves.Gravitational waves are weakly interacting, making them extraordinarily difficult to detect; at the same time, they can travel unhindered through intervening matter of any density or composition. Electromagnetic waves are strongly interacting with normal matter, making them easy to detect; but they are readily absorbed or scattered by intervening matter.

Gravitational waves give holistic, sound-like information about the overall motions and vibrations of objects. Electromagnetic waves give images representing the aggregate properties of microscopic charges at the surfaces of objects.
Gravitational charge is equivalent to inertia.
Electromagnetic charge is unrelated to inertia.
This is the more fundamental difference between electromagnetism and gravity, and influences many of the details of gravitational radiation, but in itself is not responsible for the dramatic differences in how we perceive these two types of radiation. Most of the consequences of the principle of equivalence in gravity have already be discussed, such as:The fundamental field of gravity is a gravitational force gradient (or tidal) field, and requires an apparatus spread out over some distance in order to detect it. The fundamental field in electromagnetism is an electric force field, which can be felt by individual charges within an apparatus.The dominant mode of gravitational radiation is quadrupolar: it has a quadratic dependence on the positions of the generating charges, and causes a relative "shearing" of the positions of receiving charges. The dominant mode of electromagnetic radiation is dipolar: it has a linear dependence on the positions of the generating charges, and creates a relative translation of the positions of receiving charges.

Answer:

1) Gravitational force and electromagnetic force both are field forces which means both forces exerted from long range of distance and we do not require any physical contact to apply these type of forces.

2) Now we also know that

$F_g = (Gm_1m_2)/(r^2)$

$F_e = (kq_1q_2)/(r^2)$

both the forces are inversely depends on the square of the distance between two charges or two masses

so both forces follow inverse square law.

Now two ways they are alike is

1) gravitational force never exist in form of repulsive force while electromagnetic force is either repulsive or attractive.

2) Gravitational force is independent of the medium between two masses while electromagnetic force is dependent on the medium between two charges

URGENT PLEASE BRAINLIESTAssuming the starting height is 0.0 m, calculate the potential energy of the cart after it has been elevated to a height of 1.0 m above the starting location

Answers

When the cart arrives at any place that's 1.0 meter higher than where it started, its potential energy will be

(9.8) · (its mass on kilograms) Joules .

Final answer:

Potential Energy is given by the formula mass x gravity x height. The starting height is irrelevant in its calculation. The potential energy depends on the mass of the object, gravity and the elevated height.

Explanation:

The potential energy of an object is calculated by the formula Potential Energy = mass x gravity x height. Whenever the height of an object increases, its potential energy will increase as well provided mass and the gravitational field (g) remain constant. Here, the starting height being 0.0 m is irrelevant to the calculation of potential energy at 1.0 m height. If the mass of the cart and the value of gravity (usually taken as 9.8 m/s2 on Earth's surface) are known, you can substitute those values into the formula to find the potential energy.

e.g. If the mass of the cart was 2 kg, the potential energy at a height of 1.0 m would be 2 kg x 9.8 m/s

x 1.0 m = 19.6 joules.
