Answer:
Let's start by understanding what exactly a scientific question is. A scientific question is a question that may lead to a hypothesis and help us in answering (or figuring out) the reason for some observation. A good scientific question has certain characteristics. It should have some answers (real answers), should be testable.
Here's examples of a few:
Why is that a star?
or
What is that star made of?
Hope this can lead you to the answer you're looking for at least!!
The end or finish of an event or process.
You can solve this by using Newton's First Law or Newton's Second Law.
1) Newton's First Law or Inertia Law states that in the abscense of a net force acting over an object, this will not chage its state of movement, i.e it will remain at rest (if it is no moving) or with uniform movement (if the object is moving).
2) Newton's Second Law: Net force = mass * acceleration => acceleration = net force / mass = 0 / mass = 0.
Zero accelerations means rest or uniform movement.
First Law is implicit in Second Law.
Answer:40kg m/s
explanation: momentum =mass x velocity
Train has the most momentum if they were all traveling 50 mph
<u>Explanation:</u>
- A train can have the most momentum even if it is moving slowly because it has a large mass if they were all traveling 50 mph.
- In simple words, momentum can be described as the amount of motion of a moving body, estimated as a product of its mass and velocity.
- <u>Momentum= mass x velocity</u>
