Answer:
For example, an earthquake of magnitude 5.5 releases about 32 times as much energy as an earthquake measuring 4.5. Another way to look at this is that it takes about 900 magnitude 4.5 earthquakes to equal the energy released in a single 6.5 earthquake.
Explanation:
The correct answer is heterozygous.
Answer:
(D) F/2
Explanation:
Since the circular section is unbanked, the centripedal acceleration acting on each of the cars is


Therefore the centripetal force on each car


Since
this means the friction force required to keep the large car on the road is only half of the friction force required to keep the small car on road
So (D) F/2 is the correct answer
