Aradiation detector measures the radioactivity of a piece of radium by catching and counting alpha particles it emits. according to quantum physics, making this measurement affects the

The measurements are affected by the air mass

Explanation:

The radioactive emission consists of alpha, beta and gamma rays.

The alpha particles are helium nuclei, with two positive charges and four um, so they are quickly stopped, by the layer of air around the emission zone, part of Radio.

Beta particles are electrons with a negative charge and the mass of the electron, they penetrate the air layer more and need denser materials to stop them

Gamma rays are waves of electromagnetic radiation, without electric charge or resting mass, which are very difficult to stop

With the above the sentence should be completed:

 The measurements are affected by the air mass

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
