Answer: has zero mass

is an electron

has a -1 charge

is electromagnetic energy

Explanation:

A beta-particle is an electron emitted from the nucleus of an atom following the decay of a neutron into a proton. Beta rays are deflected by a magnetic field in a direction that indicates a negative charge, thus they are electromagnetic in nature.

The beta particle released is basically a electron with -1 charge and no mass.

General representation of beta particle in the form of _Z^A\textrm {X} given as _{-1}^0e

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

A gas occupies 3.60 L when the temperature is 45.0oC and at 1.02 atm of pressure. What temperature change (in K) will be needed
dedylja [7]
As we know V1/T1=V2/T2
so,   V1=3.60
        V2=6.25
        T1=45c=318k
        T2=required
solution!
            T2=V2 multiply by T1/V1 so
   put the values and find your answer which should be 552k
