I think the answer is significant
For the forces to be in equilibrium:
F 1 + F 2 + F 3 + F 4 = 0
i + j + i - j + 9 i + 2 j + F 4 = 0
11 i + 2 j + F 4 = 0
F 4 = - 11 i + 2 j
F 4 = ( -11, - 2 )
Answer:the correct answer is 1.0* 10^-7 mol/L
Explanation:
The correct answer is
(1) a 15-kg mass traveling at 5.0 m/s
<span>In fact, the inertia of an object depends only on its mass. The inertia gives a measure of "how hard is to put an object in motion", or "how hard is to stop an object in motion": the greater the mass, the larger the inertia of the object. In this problem, we have 4 objects, and the object with greatest mass is the first one (15 kg), therefore this is also the object with greatest inertia.</span>
<h2>Yes, it has cell structure with a membrane and nucleus.</h2>
