It is about density. The less dense object will tend to float when put into the water. For example, oil is denser than water so the result of the mixture would make oil float. Sinking objects would only mean that it has an equal or greater mass than water.
Answer:
0.045 J
Explanation:
The work done on a charge moving through a potential difference is given by

where
W is the work done
q is the charge
is the potential difference
In this problem, we have
q = 0.0050 C is the charge
is the potential difference
Using the formula, we find the work done:

DIAMONDS are NOT rocks. Diamonds are minerals, rocks are made up of many different fragments of minerals.
Answer:
P = 517.5 [kg*m/s]
Explanation:
We must remember that momentum is defined as the product of force by the time of force duration.

where:
P = momentum [kg*m/s]
F = force [N]
t = time [s]
![P=345*1.5\\P=517.5[kg*m/s]](https://tex.z-dn.net/?f=P%3D345%2A1.5%5C%5CP%3D517.5%5Bkg%2Am%2Fs%5D)
