Emissions from alpha decay require the least amount of shielding. which best describes why the emissions from alpha decay are so easily blocked compared to the emissions of other types of radioactive decay?

alpha decay releases visible light, which has less energy than the light released during gamma decay.

alpha decay releases particles that have less mass and charge than the particles released during beta decay.

alpha decay releases particles that have less mass and charge than the particles released during gamma decay.

alpha decay releases particles that have more mass and charge than the particles released during beta decay.

Alpha decay releases particles that have more mass and charge than the particles released during beta decay.

Explanation:

In the alpha decay, an alpha particle is emitted. An alpha particle is a nucleus of helium, consisting of two protons and two neutrons. The particle emitted in the beta decay is instead an electron: therefore, the alpha particle has more mass and more charge than a beta particle. For this reason, alpha particles are much more ionising than electrons, so they release much more energy per unit distance than beta particles, and so they lose all their energy much faster than beta particles. This is why alpha particles can be easily blocked even by a thin piece of paper, while beta particles are able to pass through.

glen is correct.

step-by-step explanation:

glen is correct because when you multiply 4 * 2 = 8.

and 4 * 3 = 12.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
