Answer:
A scientific hypothesis
Explanation:
A scientific hypothesis is an idea or explanation for a fairly narrow set of phenomena that you then test through research, experimentation, experience, scientific background knowledge, preliminary observations, and logic. They are the initial building block in the scientific method and they are also beyond a wild guess but less than a well-established theory.
Answer:
The recoil speed of Astronaut A is 0.26 m/s.
Explanation:
Given that,
Mass of astronaut A,
Mass of astronaut B,
Astronaut A pushes B away, with B attaining a final speed of 0.4,
We need to find the recoil speed of astronaut A. The momentum remains conserved here. Using the law of conservation of linear momentum as :
So, the recoil speed of Astronaut A is 0.26 m/s.
Answer:
Position.
Explanation:
Motion can be defined as a change in location with respect to a reference point.
This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.
Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement etc.
A complete description of your position includes a distance, direction, and reference point. Thus, this includes an object's distance in a certain direction from a reference point.
Answer:
The answer is A.) Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on the object.
Explanation:
Your weight would change if you went to the moon because the gravitational pull is different but your mass would stay the same because the amount of matter in you wouldnt change.
The answer is horsts and grabens.
