Answer:
Heat the solution, dissolve the solute, and let it cool verifying nothing settled out.
Explanation:
F=1/T
therefore T=1/F
so thats T=1/20x10^6
T=5x10^-8seconds
Answer:
45°.
It is a property of the parabolas.. When the angle between a parabola and the x-axis is 45° the range is maximum.
Answer: the potental with twice larger radius 0.5* Vo ( being Vo =100V)
Explanation: In order to solve this proble, we know that teh potential due to charged sphere relative V=0 at infinity, we have
Vo=k*Q/R where R is the sphere radius
if we enlarge the radius to 2R the
V= k*Q/2*R = Vo/2
