If the kinetic energy of an object changes, then the collision is considered inelastic. This is regardless of whether the objects sticks together or not.
My best answer for this question would be D) inelastic, because kinetic energy is not conserved.
We can tell from the collision that it is not elastic.
Momentum is is conserved, it transfers to the other player.
Kinetic energy is not conserved, at it turns into internal friction.
I hope this helps! :)
Answer:
no it would not. that is an open circuit and it would need to be closed at the switch for current to flow.
Answer:
option A
Explanation:
given,
compression for lower setting = x
work done to compress in lower setting = 5 J
compression in higher setting, x' = 2 x
work done in higher setting = ?
Work done in compression of spring at lower setting
............(1)
Work done in compression of spring at higher setting
from equation (1)
W' = 20 J
Work take for the higher setting is equal to 20 J
Hence, the correct answer is option A
Answer:
Iron
Explanation: It is by mass the most common element on Earth, right in front of oxygen, forming much of Earth's outer and inner core.
Answer:
Hypotheses must be testable, and once tested, they can be supported by evidence. If a statement is made that cannot be tested and disproved, then it is not a hypothesis.
