Answer:
The net force acting on the box is 2N to the left.
Explanation:
The net force acting that is on an object is the sum of all of the individual forces acting on it.
If two forces act on an object in opposite directions, the net force is the difference between the two forces. In this case, the net force is always greater than or equal to zero but less than either of the individual forces.
If two forces act on an object in the same direction, the net force is the sum of the two forces. In this case, the net force is always greater than either of the individual forces.
Here in the figure the two forces acting in opposite direction on the object.
The direction of the resultant force is same direction as the force with the larger magnitude
Thus the net force is 2N to the left
False. I’m not that sure but that’s what I think.
Answer:
<h2>Because water can lose and accept H + ions .......</h2>
Answer:
t=5.2seconds
Explanation:
First, we state our assumptions:
Given
and gas stream
We use the time constant to find the diameter of the junction:
Now, check the validity of the lumped system analysis. With
#Lumped Analysis is OK
Bi<<0.1, therefore the lumped approximation is excellent. The time required for the junction to reach :
It takes 5.2seconds for the junction to reach 199 oC
