An isotope undergoes radioactive decay by emitting radiation that has a –1 charge. What other characteristic does the radiation
weeeeeb [17]

<u>Answer:</u> The radiation emitted will have negligible mass number.

<u>Explanation:</u>

Radioactive decay is defined as the process in which an unstable nuclei breaks down into stable nuclei via various methods.

An isotope undergoes a radioactive decay to attain stability.

There are three types of decay process, but the process in which the emitted radiation carries a charge of -1 is beta decay.

Beta decay is defined as the decay process in which a neutron gets converted to a proton and an electron.  In this decay process, beta particle is emitted. The emitted particle carries a charge of -1 units and has a mass of 0 units. The released beta particle is also known as electron.

_Z^A\textrm{X}\rightarrow _{Z+1}^A\textrm{Y}+_{-1}^0\beta

Hence, the radiation emitted will have negligible mass number.

A force of 5 N produces an acceleration of 2 m/s2 on the object. What is the mass of the object?
hichkok12 [17]

Hello!

A force of 5 N produces an acceleration of 2 m/s2 on the object. What is the mass of the object ?

Data:

F (force) = 5 N

m (mass) = ?

a (acceleration) = 2 m/s²

Solving:

F = m*a

5 = m*2

2\:m = 5

m = \dfrac{5}{2}

\boxed{\boxed{m = 2.5\:kg}}\end{array}}\qquad\quad\checkmark

Answer:  

2.5 kg

Nicholas sends 20.0 minutes ironing shirts with his 1800-watt irn . How many joules of energy were usedby the iron
Nuetrik [128]
1 watt = 1 joule/sec
1800 watts = 1800 joules/sec

                 (1800 J/sec) x (20 min) x (60 sec/min)

             =  (1800 x 20 x 60) joules  =  2,160,000 joules .

                                                             ( 2.16 megajoules )
