Answer: the answer is B the lower the resistance,the higher the conductivity
Explanation:
Resistance is inversely proportional to conductivity,the lower the resistance the higher the conductivity,the metal silver has a very low resistance,thus it conductivity is high
Answer:
Average speed = (2x+3y)/5 miles/hour
Explanation:
Average speed is the total distance travelled per unit time.
Average speed = total distance/total time taken
Given;
1. Travelled x miles per hour for 2hours.
2 travelled y miles per hour for 3 hours.
Distance covered is;
1. Distance = speed × time
d1 = x × 2 = 2x
2. d2 = y × 3 = 3y
Total distance travelled = d1+d2 = 2x + 3y
Total time taken = t1+t2 = 2+3 = 5hours
Average speed = (2x+3y)/5 miles/hour
Answer:
is called an orbit
Explanation:
a satellite is any natural or artificialobject that revolves around an object in space, just as the moon revolvesaround Earth.
