Answer:
Kilogram(kg) is the SI unit for mass while kilometre(km) is a unit for length. They are both similar in that they are 10^3 of a unit, thus kilo. As kilogram represents mass, it is a measure of how much matter is present in an object. While kilometre is a measure of distance/how long or short an object is.

Answer:
218 N
Explanation:
The weight of the object on Uranus W = mg' where m = mass of the object = 25.0 kg and g' = gravitational acceleration.
Since in the table, we are given different values, we look for the value of the gravitational acceleration because, that is the only variable there that can help us calculate the weight of the object.
From the table, the gravitational acceleration g' = 8.7 m/s².
So, the weight of the object W = mg'
= 25.0 kg × 8.7 m/s²
= 217.5 N
≅ 218 N
Answer:
It is the force that is present because of the mass of our planet. it's what keeps us stuck on the surface of Earth rather than floating off into space.
The answer is D.paleomagnetism
