Answer:

Generally with successive half-life a new element is formed from the decayed nuclei:

isotope - daughter nucleus has same no. of protons (same atomic number) so the same element is formed in the decay

isotone - daughter nucleus has same number of neutrons so the atomic number has changed and a new element is formed (new atomic number)

isobar - daughter nucleus has same mass number - this could be an example of beta decay where the decayed nucleus has the same mass number but loses a neutron and gains a proton because of the lost electron and a new element is formed with the atomic number increases by 1

Example:

U238 Uranium - alpha to Th234

Th234 Thorium - 2 beta to U234 (back to U but atomic mass less by 4)

U234 Uranium - alpha to Th230

Th230 Thorium - alpha to Ra226

etc. but during beta decay (electron loss) a neutron is lost and a proton gained (answer a)

How are fingerprints identified and collected at the crime scene?

padilas [110]

One of the most common methods for discovering and collecting latent fingerprints is by dusting a smooth or nonporous surface with fingerprint powder (black granular, aluminum flake, black magnetic, etc.). If any prints appear, they are photographed as mentioned above and then lifted from the surface with clear adhesive tape. The lifting tape is then placed on a latent lift card to preserve the print.

If you are rowing a boat, you should be most concerned if you see a wave with which characteristic? help asap pls

3241004551 [841]

The best answer would be C. Amplitude is the measure of the distance between the crest and the center of the line, or the distance between the trough and the center of the line (like wave height). High waves are a sea danger, especially to small ships and rowboats.

What is the toy's total energy at any point of its motion? Express your answer with the appropriate units.]

suter [353]

The complete question is as follows:

A 0.150-kg toy is undergoing SHM on the end of a horizontal spring with force constant k = 300 N/m. When the toy is 0.0120 m from its equilibrium position, it is observed to have a speed of 0.400 m/s.

Answer:

The correct answer is 0.034 J.

Explanation:

Given :

mass of the toy is m = 0.15 kg.

The force constant of restoring force k = 300 Nm⁻¹

When the position of the toy from the equilibrium is x = 0.012m, then the

speed of the toy vx = 0.4m s

The total mechanical energy in SHM is given by

E= 1/2 (mv²+ kx²) = 1/2 kA²

(here, m = mass of the object, vx = velocity, k = force constant

of restoring force, and A = amplitude of SHM.)

Hence by substituting the numerical values in equation 1, we get

$E= \frac{1}{2} (0.15* 0.4) + \frac{1}{2} (300* 0.012)$

= 0.034 J

Thus, the correct answer is 0.034 J.
