What is science?
Science is the methodical, empirically-based pursuit and application of knowledge and understanding of the natural and social worlds.
A method of learning about the world is science. Science allows people to participate in the creation of new knowledge as well as use that knowledge to further their goals. It is both a process, a product, and an institution.
Thus, The first person to observe the planets through a telescope was Galileo Galilei.
Based on relativity, Albert Einstein created a model of the universe.
A technique to determine the separation between celestial bodies was demonstrated by Henrietta Swan Leavitt.
Edwin Hubble demonstrated the expansion of the universe
According to Georges Lemaître, the universe had a beginning.

One very useful definition if energy is "the ability to do work".
Final answer:
The best description of the 'ability to do work' is 'energy'. This concept explains the capacity an object has to perform action and can be illustrated by different forms of energy like potential or kinetic.
Explanation:
The ability to do work is best described by c. energy. In physics, energy is the capacity to do work. Objects can hold this ability until it's converted into action, like lifting a box or lighting a bulb. This concept applies to various forms of energy such as potential energy, kinetic energy, and more. For example, a boulder at the top of a hill has potential energy due to its position, which can be converted into kinetic energy (work) as it rolls down.

no matter where the object goes.
The weight of the object is
(mass) x (gravity in the place where the object is) .
On the surface of the Earth,
Weight = (60 kg) x (9.8 m/s²)
= 588 Newtons.
Now, the force of gravity varies as the inverse of the square of the distance from the center of the Earth.
On the surface, the distance from the center of the Earth is 1R.
So if you move out to 5R from the center, the gravity out there is
(1R/5R)² = (1/5)² = 1/25 = 0.04 of its value on the surface.
The object's weight would also be 0.04 of its weight on the surface.
(0.04) x (588 Newtons) = 23.52 Newtons.
Again, the object's mass is still 60 kg out there.
___________________________________________
If you have a textbook, or handout material, or a lesson DVD,
or a teacher, or an on-line unit, that says the object "weighs"
60 kilograms, then you should be raising a holy stink.
You are being planted with sloppy, inaccurate, misleading
information, and it's going to be YOUR problem to UN-learn it later.
They owe you better material.
Answer:
23.5 N
Explanation:
Just wanted to clarify something about the verified answer: Our only given measurement—the mass of the object—has 3 significant digits, so we can only include 3 significant digits in our answer.
23.52 N is NOT the correct answer. Your answer should only have 3 significant digits.
I just did the quiz where this problem came from, so I know that 23.5 N is the correct answer.

The train will pass the 1500.0m marker 33.33 seconds after leaving the station. Its velocity is 162.0 km/h.
How to evaluate time the train will pass the 1500.0m marker and it's velocity
To find the time it takes for the train to pass the 1500.0m marker, we can use the formula: time = distance / velocity. Plugging in the values,
time = 1500.0m / 45.0 m/s
time = 33.33 seconds.
To convert the velocity from m/s to km/h, we use the conversion factor: 1 m/s = 3.6 km/h. Therefore,
velocity = 45.0 m/s * 3.6 km/h/m/s
velocity = 162.0 km/h.
In summary, the train will pass the 1500.0m marker approximately 33.33 seconds after departing the station, and its velocity will be 162.0 km/h
