Answer:
(4) The physical and chemical properties of these minerals determine how humans use them.
Explanation:
All the materials and the metals found on earth shows certain characteristics naturally or in their physical state. These physical characteristics can be their look, their structure, their color, strength, melting point, boiling point, density, etc.
And chemical properties of the metals are defined as those characteristics or features of the metals that it exhibits when these metals reacts chemically.
The physical properties as well as the chemical properties distinguishes each metal from each other. These properties determines how people use these metals in their life.
The correct answer is the wavelength of the light. Good luck m8
Answer:
solute + solvent = solution
Explanation:
solute is <em>Any substance that is dissolved in a liquid solvent to create a solution</em>
solvent is <em>A liquid that dissolves a solid, liquid, or gaseous solute, resulting in a solution.</em>
and.
solution is <em>A homogeneous mixture, which may be liquid, gas or solid, formed by dissolving one or more substances.</em>
Answer:
q = -7.691 × 
C
so magnitude of charge is 7.691 × C
and negative sign mean charge is negative potential
Explanation:
given data
electric potential = −2.36 V
distance = 2.93 mm = 2.93 × 
m
to find out
What are the sign and magnitude of a point charge
solution
we know here that electric potential due to charge is
V = 
..............................1
here k is coulomb force that is 8.99 ×
Nm²/C² and r is distance and q is charge and V is electric potential
put here all value we get q in equation 1
V =
-2.36 = 
q = -7.691 × C
so magnitude of charge is 7.691 × C
and negative sign mean charge is negative potential
Answer:
a. the product of the current and the time interval
Explanation:
the basic formula is: 
current means the time rate of flow of charge: 
where Q - charge
I - current
t - time
