Answer:
The gravitational force on the moon is less than on Earth, because the strength of gravity is determined by an objects' mass. The bigger the object, the bigger the gravitational force. Gravity is pretty much everywhere
Explanation:
Why might astronauts choose to “lope” or hop rather than walking or running on the moon? Astronauts can “lope” in the moon's low gravity levels, even though this gait pattern is very difficult to use on Earth.
<u>Answer</u>: oscillating universe theory
<u>Explanation</u>:
- The <em>oscillating universe theory</em> is a modification of the famous big bang theory.
- According to this theory, there are successive cycles of expansion and contraction that occurs in the universe and due to the contraction, the universe gets confined into a very small volume which has a large density.
- When the universe gets confined in such a way then, it is said that a 'bounce' will occur and,<em> it would thus oscillate between the big bang and the big crunch.</em>
- Thus, this theory states that for<em> every big bang there is a big crunch.</em>
Answer:
Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone.
