Answer:
The change in momentum equals the area under the graph (the impulse). That area is 4N * 3s - 2N * 2s = 8 N s. Therefore . m delta(v) = 8 kg m/s. 1.2 kg * ( v(6) - v(0) ) = 8 kg m/s
Explanation:
A)An object cannot remain at rest unless the net force acting on it is zero. B) If a block is moving to the left with constant velocity the net force applied to the block is zero. C) A block of mass 2 kg is acted upon by two forces: 3N (directed to the left) and 4N (directed to the right).
The rationale behind usability testing is that getting input from real users at the beginning of a project is essential to the design process.
<h3>What is the rationale behind usability testing?</h3>
The primary aim of a usability test is so as to make better a design.
Note that in any usability test, real users are made to try and cary out or accomplish some goals, or tasks, via the use of a product under some controlled conditions.
Therefore, The rationale behind usability testing is that getting input from real users at the beginning of a project is essential to the design process.

<span>Our Sun will slowly get hotter as more and more Helium accumulates in the Sun's core. In ~1 billion years, liquid water will no longer be possible on Earth's surface, and the oceans will completely boil away, resulting in a Venus-like planet. Only thermophyllic bacteria may be able to survive, perhaps at the poles. In ~4-5billion years, our Sun will have converted ~10% of its Hydrogen to Helium, and thus become so hot that Helium to Carbon fusion will begin in earnest, causing the "Helium flash" which will convert our Sun into a red giant, and swallow and vaporize all of the rocky inner planets. It may even blow off a planetary nebula. (Contrary to what the others have said, our Sun will not 'run out' of Hydrogen.) </span>
Answer:
