Are beta particles positive or negative?
Beta particles can be either positive or negative. It depends if an electron or a positrion is emited. Usually though, beta particles are negative as it is much more common for an electron to be emitted (though that does depend on the substance).
Typical greek letter used in denoting a angle?
alpha, beta, and theta are commonly used for this.
How do you find the length of the arc if r equals 9.234 mm beta equals 5 pi over 4?
It depends on which angle beta is: the angle subtended by the arc at the centre of the circle (assuming that it is a circle and not an ellipse or some other shape), otr the angle subtended by the chord and one of the radii. Basically, there is not enough information provided in the question to give a sensible answer.
What does alpha mean in math?
Normally, alpha is used to represent an angle. Just like "x" is used to represent an unknown number or angle, alpha, theta, beta are used to represent unkown angles.
What is the approximate size of the smallest angle of a triangle whose sides are 4 5 and 8?
Why approximate? I will show you what you should know being in the trig section. Law of cosines. Degree mode!! a = 4 (angle opposite = alpha) b = 5 ( angle opposite = beta) c = 8 ( angle opposite = gamma ) a^2 = b^2 + c^2 - 2bc cos(alpha) 4^2 = 5^2 + 8^2 - 2(5)(8) cos(alpha) 16 = 89 - 80 cos(alpha) -73 = -80 cos(alpha) 0.9125 = cos(alpha) arcos(0.9125) = alpha alpha = 24.15 degrees ------------------------------ b^2 = a^2 + c^2 - 2bc cos(beta) 5^2 = 4^2 + 8^2 - 2(4)(8) cos(beta) 25 = 80 - 64 cos(beta) -55 = -64 cos(beta) 0.859375 = cos(beta) arcos(0.859375) = beta beta = 30.75 degrees --------------------------------- Now to find gamma, subtract from 180 degrees 180 - 24.15 - 30.75 = 125.1 degrees alpha = 24.15 degrees ( subject to rounding, but all add to 180 degrees ) beta = 30.75 degrees gamma = 125.1 degrees now you see the smallest, the angle opposite the a side, which is 4 ( be in degree mode!!)
How do you do an experiment to investigate how magnetic flux affects the angle through which beta particles are deflected?
You need to have some method of measuring the angle, such as a 360 degree protractor; a hall probe; a way to remove radiation, such as some paper; beta radiation; and the current in the Helmholtz must be changed to vary the magnification field density. Be sure to repeat readings, calibrate the hall probe, keep the separation of the coils constant, and correct the deflection of beta radiation on the diagram.
What correctly describes the charge of beta particles and alpha particles?
Beta particles, from beta- decay, have a charge of -1. Beta particles, from beta+ decay, have a charge of +1. Alpha particles have a charge of +2.
Can paper shield beta particles?
Beta particles are not stopped by a paper sheet.
What geiger counter measure?
A geiger counter measures radioactivity. It detects the emission of nuclear radiation from alpha particles, beta particles, and gamma rays.
What is a soft beta particle?
Low energy beta particles, say, from tritium, are called soft beta particles.
The transformation of 92U238 into 82Pb206 the number of alph and beta particles is what?
alpha particles=8 and beta particles=6
How can you prevent beta particles?
Thin sheet or plastic may prevent beta particles.
What are the everyday uses of Beta particles?
Beta particles are often used in smoke detectors.
What is the charge of beta particles?
Beta Particles have a negative charge,In Beta decay a neutron changes into a proton and a beta particle, an electron.
What is the range of beta particles in the air?
The range of beta particles in the air is up to several hundred feet. Beta particles are emitted by specific types of radioactive nuclei. Potassium-40 is a type of radioactive nuclei that emits beta particles.
What type of nuclear radiation can be blocked by a block of lead Beta particles or alpha particles?
Both Beta and alpha particles can be blocked by a block of lead. Alpha particles can even be blocked by a sheet of paper, and beta particles can be blocked by a thin aluminium plate.
Why are alpha and beta rays deflected in opposite directions in a magnetic field?
An alpha particle, which is a 24He nucleus, has a mass of 4 and a charge of +2. A beta particle has a charge of +1 or -1, depending on whether it is a positron (beta +) or an electron (beta -). It's mass is minuscule compared to the alpha particle, and it will undergo a comparatively huge deflection in the same field as an alpha particle would. Though the alpha particle has twice the charge as a beta particle, it has several thousand times the mass of that beta particle. As it is so much more massive than the beta particle, its inertia will be much more difficult to overcome even though it has twice the charge.
