Answer:
57.1 km/hr
Explanation:
To find the average speed you take the total distance divided by the total elapsed time.
So, the total distance is 140 + 60 = 200
the total elapsed time is found by taking 140/70=2 and 60/40=1.5
2+1.5=3.5
The plug the numbers into the equation,
200/3.5=57.1

Answer:
A., B., and C.
Explanation:
An Ohmic material is a material that obeys Ohm's Law, V = IR.
In contrast, a non-Ohmic material is one that does not obey Ohm's law.
Ohm's law states that the voltage across an electrical object is proportional to the current flowing through it, with the constant of proportionality being Resistance, R (in Ohm's).
The only Non-Ohmic material is the semiconductor, as semiconductors do not obey Ohm's law.
