The first hill is 61 m higher than the station. The mass of the empty cars is 550.5kg. The cars can carry up to 12 people, each with a mass of 150 kg. What are the least amount of energy the launch system must transfer to the cars when they are empty and when they are full to make sure the cars have enough energy to complete the course?

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
