Explanation:
just took the test
The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J
What is potential energy ?Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.
mass(m) = 10kg
g (acceleration due to gravity) = 9.8m/s^2
altitude(height (h)) = 400m
Meteor's Potential energy = m * g * h
= 10 * 9.8 * 400 = 39200 J
correct option will be a) 39200 J

1. How do i determine the kinetic energy of the truck?The kinetic energy of the 6000 Kg truck can be obtained as follow:
Mass of truck (m) = 6000 KgVelocity of truck (v) = 92 Km/h = 92 / 3.6 = 25.56 m/sKinetic energy of truck (KE) =?KE = ½mv²
KE = ½ × 6000 × 25.56²
KE = 1959940.8 J

How do factors such as ocean currents, water temperature, and weather affect you in your daily life?
Answers
Answer:One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm.
Explanation:The majority of radiation from the Sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.

Explain how scientists are able to estimate the age of the solar system.
They use radioactive dating with samples of meteorites.
They use relative dating with the layers of the moon's surface.
They use radioactive dating with samples of moon rock.
They use relative dating with the layers of the Earth's surface.
Answers
Scientists are able to estimate the age of the solar system by the use of radioactive dating with samples of meteorites. Hence, option A is correct.
What is Radioactive Dating?Radioactive isotopes are used in radioactive dating to determine the age of rocks and minerals. For igneous and metamorphic rocks, which cannot be dated using the stratigraphic correlation approach for sedimentary rocks, this method is helpful.
The atomic nucleus becomes unstable and releases bits and pieces during radioactive decay, which is a natural process. As radioactive particles, they are discharged (there are many types). The atom becomes stable when the number of protons and neutrons in the nucleus is balanced as a result of this decay process.
To try and determine the age of the Solar System, we can look at the oldest meteorites or those that exhibit the most severe lead ratios; if we do so, we find that the age is approximately 4.568 billion years. Rocks from the Moon, which have not experienced the same geological processes as rocks from Earth, are available for examination.
Hence, it concludes that option A is correct.

Does the moon have gravity? How do you know? Support your answer using evidence.
Answers
Answer:
Gravity is experienced on the moon but since the moon is much smaller and has less mass than the Earth, the gravitational pull on the surface is lower compared to that on the surface of Earth.
Explanation:
Yes, the moon has gravity. This is evidenced by the fact that it not only attracts objects on its surface, but it also influences the tides of the Earth's oceans. The moon's gravitational pull creates the distinctive tidal bulges that cause the daily rise and fall of the ocean tides. This interaction between the moon's gravity and the Earth's oceans is evidence of the moon's gravitational field. Additionally, space missions to the moon have shown that objects and astronauts on the moon's surface are subject to its gravitational pull.
