Answer:
Circle Q
Explanation:
The flux of a field through a surface is given by:

where
F is the field strength
A is the area of the surface
is the angle between the direction of the field and the normal to the surface
In the figure, we see that the 4 surfaces have different orientations, so different angle
. In the formula, we see that the flux is maximum when
, which occurs when the field is perpendicular to the surface, and the flux is zero when
, (because
) which occurs when the field is parallel to the surface.
In the figure, we see that circle Q is parallel to the direction of the field, so in this case the field is zero, while in all the other cases is not.
So, the correct answer is
Circle Q
<span>This is a true statement. Fitness is typically a long-term solution, not a short-term repair. When looking for fitness results, it will usually take weeks to months to see any tangible results, even though there could be some short-term benefits such as increased energy. This is why fitness is sometimes seen as a lifetime endeavor and not one that occurs overnight.</span>
Answer:
Efficiency of the machine = 75%
Explanation:
Given:
Input work = 8,000 J
Output work = 6,000 J
Find:
Efficiency of the machine
Computation:
Efficiency of the machine = [Output work / Input work]100
Efficiency of the machine = [6,000 / 8,000]100
Efficiency of the machine = 75%
As the time of motion increases, the velocity of the object increases downwards.
The given parameters;
- <em>acceleration due to gravity, g = -9.81 m/s²</em>
- <em>velocity of the object, v₀ = 9.8 m/s</em>
The final velocity of the object at different time is calculated as follows;
<em>when the time = 1 second;</em>
v = v₀ - gt
v = 9.8 - 9.8(1)
v = 0
<em>when the time = 2 second;</em>
v = v₀ - gt
v = 9.8 - 9.8(2)
v = -9.8 m/s
<em>when the time = 3 second;</em>
v = v₀ - gt
v = 9.8 - 9.8(3)
v = -19.6 m/s
Thus, we can conclude that as the time of motion increases, the velocity of the object increases downwards.
