Answer:
D. 18.60
Explanation:
By the law of conservation, the momentum is neither loss nor gained but instead transfered. When they crash into each other, and stick, they combine to create a total mass of 215 kg. Since the momentum is transfered, the two objects, combined, have a total momentum of 4000 kg-m/s. We know that momentum equals mass times velocity. You then divide 4000 by 215 and get approximately 18.6 m/s
Answer:
Atoms are single neutral particles.
example: Ne, O
Molecules are neutral particles made of two or more atoms bonded together.
example:O2,HCl
The object will move if the forces are unbalanced.
Newtons second tells you that when a net force (the unbalanced force) is applied to and object it will produce an acceleration (movement) in direct proportion to the force and in inverse proportion to the mass of the object.
Answer: The part of the microscope that is the circular area is the APERTURE
I hope this helped!
According to the First Law of Motion or Law of Inertia, Inertia is the tendency for an object to resist change in its velocity. If you look at your scenario you have a full water bottle on a desk and a football player running with the ball. The water bottle is at REST because is not moving while the football player is IN MOTION, because he is running.
Now the question is would it be easier to make the water bottle move or to make the football player stop?
It is easier to make the bottle move than stop the football player. Since the running football player shows more resistance to a change in its motion, then it has more inertia.
