Answer:
D. Opposes the applied flux through the conductor.
Explanation:
- <em><u>According to the Lenz's law, the direction of induced e.m.f is such that it generates a current which in turn produces a magnetic field that would oppose the change causing it.</u></em>
- In other words, the direction of any magnetic induction effect is such that it opposes the cause of the effect.
- Therefore; an induced magnetic field in a conductor, opposes the applied flux through the conductor.
Answer:
7407.4 units
Explanation:
m(t) = m(0) e^kt
Here, k = - 0.000135
So, the above equation becomes
m(t) = m(0) e^(-0.000135 t)
Compare with the standard equation of radioactivity
m(t) = m(0) e^-λt
Where, λ be the decay constant
So. λ = 0.000135
The relation between the decay constant and the mean life is
ζ = 1 / λ
Where, ζ is the mean life
So, ζ = 1 / 0.000135 = 7407.4 units
So, <u>their net force on the cart is 10 N to the right</u>.
<h3>Introduction</h3>
Hi ! Here, I will help you with the net forces (results of forces) acting on a two-dimensional area and in opposite directions. Steps that can be taken are as follows :
- Determine where the force will go, the important thing is that you are consistent until the end.
- Count the values of the force acting, the force against the direction of your mind in number 1 is given a negative sign.
- Look at the results, if it's marked (-), then choose the opposite direction from your thoughts at number 1.
The equation for calculating the net force from this two-dimensional straight line is as follows:

With the following condition :
= net force (N)
= first force and its direction (N)
= second force and its direction (N)
= You can add up the force values as many times as the question (N).
<h3>Problem Solving</h3>
We know that :
In my mind, I determined that the force will go to the right. So :
= Jose's force = 12 N >> Because he already walk to the right.
= Lucy's force = 5 N >> Because she already walk to the right.
= John's force = -7 N >> Because he is walked to the left.
What was asked :
= net force = ... N
Step by step :




<h3>Conclusion</h3>
The movement of the cart is to the right because the net force value that I calculated is not opposite (with negative sign) to the right direction. So, their net force on the cart is 10 N to the right.
