Answer:
W = Fd = 400(20) = 8000 J
Explanation:
To calculate the mass of the body moving, we use Newton's second law of motion which is F = ma where F is the force, m is the mass of the object and a is its acceleration.
F = ma
44 = m(15.3)
m = 2.9 kg
The mass of the rocket would be 2.9 kg.
Gas pressure in a closed system is caused by resultant force of all combines collisions. The correct option among all the options that are given in the question is the third option or option "C". The other options can easily be ignored. I hope the answer comes to your help.
The experimental method is usually taken to be the most scientific of all methods, the 'method of choice'. The main problem with all the non-experimental methods is lack of control over the situation. The experiment method is a means of trying to overcome this problem. The experiment is sometimes described as the cornerstone of psychology: This is partly due to the central role experiments play in many of the physical sciences and also to psychology's historical view of itself s a science. A considerable amount of psychological research uses the experimental method. <span />
