Answer:
The smaller object will move at 30 m/s
Explanation:
From the principle of conservation of linear momentum,
Momentum of objects before collision = momentum of objects after collision.
where 
are the masses and velocities of the objects 1 and 2 respectively before collision.
Hence, the object will move at 30 m/s
A independent variable is a variable which the experimenter can control and by changing the independent variable the experimenter observes or records the value of dependent variable.
so i see if you are asking independent than the answer is A.
if you are asking dependent variable than the answer may be B because manipulated by changes to the independent variable would be the best answer.
Answer:
No it is not a scientific theory.
Explanation:
An explanation of any aspect of the natural phenomenon of the world that can be tested several times and well supported by the evidence, and follows the scientific method. Furthermore known as scientific theory.
Presently, a logical hypothesis must meet a few rules, and one of those is that it must be upheld by a few (and free) strands of proof.
For this situation, we have just one hypothesis, that bulldogs are great pet and Meatball is great among bulldogs, and it isn't sufficient, at that point it can not be a scientific theory.
