Explanation:
Given that,
He walks at 3 km/hour.
If the container ship is 100 m long, and travelling at 12 km/hour.
The distance will be 200 m.
We need to calculate the relative velocity
Using formula of relative velocity

Put the value into the formula


The distance is 200 m.
We need to calculate the time
Using formula of time


Put the value into the formula


Hence, The time of oil tanker will be 80 sec.
I would go with the answer E).

Answer:
C. changes in temperature
Explanation:
The deciduous trees are the trees that shed their leaves in the autumn, and also minimize their activity during the winter months, starting to be active and grow new leaves in the spring. The main reason for this action by this type of trees is the temperature. The temperature in the winters is very low, often being far beyond the freezing point, making it very difficult for these trees to survive if they are active through it. In order to avoid severe damage or dying out in the winter, these plants hibernate, but also have developed thick bark, and very resilient roots.
1 and 3 are correct, this is due to the fact that modern technology is constantly growing and other developed nations are feeling threatened or inferior when another developed nation grows further ahead. National security has also grown global, just the threat of a foreign country developing nuclear capability is enough for another country to launch missle strikes or other acts in order to quell the threat of another nuclear capable country. 2 is not correct because industrial strategies are being shared throughout the world constantly and the safety of a country no longer stands by their standing army or navy, but by the threat of nuclear capability or a possibility of retaliation through explosive nature. Even today, most wars are done through the army holding down a line, and the navy/airforce launching long ranged missile attacks of various nature.
