Half-life is the time a. For half of a material to decay into energy b. For half of a material to decay into free protons, neutr

aniked [119]

Answer:

Explanation:

The half life of a radioactive substance is the time in which the activity of the radioactive substance becomes half of its initial activity.

The time in which the amount of radioactive substance becomes half of its initial amount in a sample.

It is denoted by T .

The relation between the decay constant and the half life is given by

$\lambda =\frac{0.693}{T}$

A body oscillates with 25hz what is its time period

Semmy [17]

Answer:

4 seconds

Explanation:

The frequency of a body is the number of oscillations in one second. It is the number of cycles per unit time. The S.I unit of frequency is the Hertz (Hz).

The period of a body is the time taken to complete one oscillation. The period is inversely proportional to the frequency of the body. It is the reciprocal of frequency and the S.I unit is second (s).

A body oscillates with 25hz. Therefore the frequency (f) = 25 Hz.

The period (T) is given as:

$Period (T)=\frac{1}{frequency(f)} \\T=\frac{1}{f} =\frac{1}{0.25}=4\\T=4\ seconds$

Why do mass numbers have a trailing decimal? use the following words describe for credit isotopes protons neutrons electrons in

Dmitry_Shevchenko [17]

Answer:a number without a decimal are generally not significant. Isotopes are atoms of same element which have the same atomic number but different number of neutrons. Isotopes of elements are represented in the following way: In an atom, the number of protons is equal to its atomic number.. An atom of an element is neutral in nature so atom contains the same number of protons and electrons.
