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.

Beginning about 55 seconds into the video, you'll see an animation of a photographer looking through her camera at a man, a set
RideAnS [48]

Answer and Explanation

The concept of parallax and relative motion is responsible for this.

That is, the photographer's motion prompts her to see parallax for the man and the trees, because their positions appear to keep shifting even though they are not really moving.

Does latitude has an effect on weight? PLEASE HELP!​
kotegsom [21]

Answer:

yes

it does you weigh less on the equator than at the North or South Pole, but the difference is small. Note that your body itself does not change. Rather it is the force of gravity and other forces that change as you approach the poles. These forces change right back when you return to your original latitude.

3.5 kJ of heat are added to a 3.4 kg block of ice at temperature of -7.6oC. Suppose the amount of heat added to the ice block is
Bond [772]

Answer:

  2

Explanation:

If the energy is doubled, the mass must be doubled (increased by a factor of 2) in order for the temperature effect to remain the same.

Heat capacity is measured in units of J/(kg·°C), so the ratio will remain constant if mass varies directly with amount of heat.
