Answer:
Volcanic ash helps scientists to determine the age of a rock sequence by using the process of RADIOMETRIC DATING
Explanation:
When scientist want to determine the age of a rock sequence, they try to find it they is a volcanic ash present. This volcanic ash tend to contains radio isotopes or radioactive elements that can be used to determine the age of the rock sequence. This process is called a Radiometric dating.
Radiometric dating can be defined as the process of dating rocks or other materials based or the known rate of decay of radioactive isotopes.
Radiometric dating has to involve parent and daughter radioactive isotopes therefore the following must be observed before carrying out radiometric dating.
a. The half life of the Parent radioactive isotopes must be known
b. The daughter radioactive isotopes must be available in substantial amounts and it must be differentiated from the parent radioactive isotopes
c. The parent radioactive isotope must have a longer half-life present in the volcanic ash as at the time of radiometric dating.
It would be hardness that in general best describes malleability, since malleability is a measurement of an objects ability to form and take difference shapes.
There is a voltage that appears between the ends of the wire. If the ends of the wire are connected, or there is a conductor between the both of them, then a current will flow in the wires. Hope it helps
(a)
The radius of the sphere is:
r = 12.5 cm
So the volume of the sphere of gold is
The density of gold is
So the mass of the sphere is
(b)
The length of one side of the cube is
L = 0.049 mm = 0.0049 cm
So the volume of the cube of platinum is
The density of platinum is
So the mass of the cube is
(c) 53.5 g
The volume of the ethanol is
V = 67.1 mL
While its density is
d = 0.798 g/mL
So the mass of the ethanol is
Answer:
Plate B will have a higher capacitance
Explanation:
One of the conditions affecting the capacitance of a capacitor is spacing between plates, the greater the spacing the lesser the capacitance and vice versa.
Hence plate B will have the B will have higher capacitance since the spacing is less when compared with that of plate A
