The data given are
melting point density
<span>Zinc 419.53 oC 7.134
Nickel 1455oC 8.912
Copper 1084.62oC 8.96
Silver 961.78oC 10.501
Gold 1064.18oC 19.282
density is the mass per unit volume. Melting point is determined by the intermolecular forces between particles in the solids.
We </span>have been asked to find which cube weighs the most
density = mass/volume
when volume is constant for all the metals, then density is directly proportional to mass. Therefore metal with highest density has the highest mass.
from the given metals, metal with highest density is Gold.
correct answer is Gold.
The next step would be to follow the AED prompts.
An AED or Automated External Defibrillator refers to a lightweight, small apparatus, which evaluates an individual's heart rhythm and can determine the irregular heart rhythms, like VF (ventricular fibrillation) or VT (ventricular tachycardia), also called Sudden Cardiac Arrest.
Automated external defibrillators can assist in saving many lives at the time of sudden cardiac arrest. However, even after training, memorizing the steps to use an AED in the right manner can be tough.
As cells die, and reproduce from time to time, educational references show that every seven years, all cells have been replaced and considered as brand new. This also applies to the skeletal system. However, this statement is still not verified by health researchers.
The answer is <span>Time is the independent variable, and the number of birds is the dependent variable. </span>
<span>An independent variable is variable that is not affected in the experiment. It is what experimenter controls. On the other side, a dependent variable is called dependent because it depends on the independent variables. It is what is affected during the experiment.
In Sam investigation, he controls time - he counts birds at 6 a.m. and 6 p.m. So, time is the independent variable. The number of birds is affected during the experiment, so it must be the dependent variable.
