Answer: No change in mass

Explanation:

Beta-emission: In this process, a neutron gets converted into a proton and an electron. The electron is referred to as a beta-particle. The beta particle released carries a charge of -1 unit and has negligible mass.

General representation of an element is given as: $_Z^A\textrm{X}$

Z= Atomic number

A = mass number

X = chemical symbol of element

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

if a mass on a spring bobs up nad down completing 2 full cycles every section. WHat are the periouds and frequency of the mass

Alika [10]

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of the time taken to complete one full cycle.

Frequency (f) will be calculated first as

f = N ÷ t

where N is the number of cycles and t is the time taken to complete one full cycle. The unit for frequency is Hertz (Hz).

To calculate the period, T, the formula below will be used

T = 1 ÷ f

The unit for period is secs

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.23 2.23 times a second. A tack is stuck in the t

elena-14-01-66 [18.8K]

Explanation:

The given data is as follows.

Angular velocity ( $\omega$ ) = 2.23 rps

Distance from the center (R) = 0.379 m

First, we will convert revolutions per second into radian per second as follows.

= 2.23 revolutions per second

= $2.23 \times 2 \times 3.14 rad/s$

= 14.01 rad/s

Now, tangential speed will be calculated as follows.

Tangential speed, v = $R \times \omega$

= 0.379 x 14.01

= 5.31 m/s

Thus, we can conclude that the tack's tangential speed is 5.31 m/s.

How do I find work and time?

Arisa [49]

Work from Days:If A can do a piece of work in n days, then A's 1 day's work = $\frac{1}{n}$ Days from Work:If A's 1 day's work = $\frac{1}{n}$ ,then A can finish the work in n daysRatio:If A is thrice as good a workman as B, then:Ratio of work done by A and B = 3 : 1.Ratio of times taken by A and B to finish a work = 1 : 3.
