What is Radiation?

Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You could also call radiation “electromagnetic waves”.

The Electromagnetic Spectrum

Illustration of electromagnetic spectrum

There is a wide range of electromagnetic radiation in nature. Visible light is one example.

Radiation with the highest energy includes forms like ultraviolet radiation, x-rays, and gamma rays.

X-rays and gamma rays have so much energy that when they interact with atoms, they can remove electrons and cause the atom to become ionized.

The Ionized Atom

illustration of radioactive atom

Radioactive atoms have unstable blends of protons and neutrons.

Radioactivity is the spontaneous release of energy from an unstable atom to get to a more stable state.

Ionizing Radiation is the energy that comes out of a radioactive atom.

Radioactive isotopes are radioactive atoms of the same element that have different numbers of neutrons.

Properties of Radioactive Isotopes

illustration of alpha particle

Radioactive atoms can give off four types of ionizing radiation: alpha particles, beta particles, gamma rays, and neutrons.

Each type of radiation has different properties that affect how we can detect it and how it can affect us.

Radioactive decay happens when an unstable atom gives off radiation and changes into a more stable atom of a different element.

The length of time it takes for half of the radioactive atoms in a group of radioactive isotopes to decay is called a half-life.

An astronaut decides to perform an experiment to monitor how much weight he loses during his stay on the International Space Sta

kumpel [21]

Answer:

The first one is: His weight on the Earth before take-off and the weight after take-off back on Earth once he gets back should be recorded as his Independent variable and his dependent variable.

The second one is: If he gained the weight back that he had lost while on the trip then you should disregard them unless that was the weight he was when he weighed himself after he got back.

The Third one is: The mass of an object is the amount of matter it contains, regardless of its volume or any forces acting on it. … Gravity is a force that attracts objects toward the Earth. The weight of the object is defined as the force caused by gravity on a mass.

A particle of mass 3m is located 1.00 m from a particle of mass m. (a) Where should you put a third mass M so that the net gravi

Airida [17]

Explanation:

It is given that net gravitational force on M is exactly equal to zero. Hence, distance to M from the bigger mass is 3m. Therefore, expression for net force will be as follows.

$F_{net} = F_{1} + F_{2} = 0$

So,

$\frac{-G(3m)(M)}{x^{2}} + \frac{G(m)(M)}{(1 - x)^{2}} = 0$

The first term is negative as the third mass is located between the other two masses. This means that 3 m will be pulling it leftwards (negative x direction) and m will be pulling it rightwards (positive x direction).

$\frac{G(m)(M)}{(1 - x)^{2}} = \frac{G(3m)(M)}{(x)^{2}}$

On dividing both sides of the equation by G.m.M, we get the following.

$\frac{1}{(1 - x)^{2}} = \frac{3}{x^{2}}$

$x^{2} = 3 - 6x + 3x^{2}$

0 = $3 - 6x + 2x^{2}$

Using the formula, $\frac{-b \pm \sqrt{(b)^{2} - 4ac}}{2a}$ the value of x comes out to be equal to +2.37 (not usabale) and -0.634 (usable).

Hence, we can conclude that the third mass will be located 0.634 meters away from the 3 m mass.

two coils close to each other have a mutual inductance of 32 mh. if the current in one coil decays according to , where i0

Harlamova29_29 [7]

The EMF induced in the second coil is 43 Volts.

Michael Faraday was the first to discover electromagnetic induction back in the 1830s. Faraday discovered that moving a permanent magnet in and out of a coil or a single loop of wire caused an electromotive force, or EMF—otherwise known as a voltage—to be produced.

Changing magnetic flux results in varied currents flowing through the coil, which in turn generates its own magnetic field. This self-induced EMF opposes the change that is creating it, and the stronger the opposing EMF is, the faster the rate at which the current is changing. According to Lenz's law, this self-induced EMF will oppose the change in current in the coil, and because of its orientation, it is typically referred to as a back-EMF.
