Answer:
<h2>Case i) if

</h2><h2>So initially if the circuit is inductive in nature then its net impedance will decrease after this</h2><h2>Case ii) if

</h2><h2>So initially if the circuit is capacitive in nature then its net impedance will increase after this</h2>
Explanation:
As we know that the impedance of the circuit is given as

when we join another identical capacitor in parallel with previous capacitor in the circuit then we will have for parallel combination

so it is

now we have

Case i) if 
So initially if the circuit is inductive in nature then its net impedance will decrease after this
Case ii) if 
So initially if the circuit is capacitive in nature then its net impedance will increase after this
a) Southward you need to apply right hand rule. If you close your hand to the east, your thumb will indicate south.
b) Given the equation for Magnetic Force

Replacing


c) Given the second Newton's Law by


Given the electric force by,



Answer:
1 is c 2 is a and 3 is b hope that helped!
Answer:
20,850 N
Explanation:
We can solve the problem by using second Newton's Law:

where
F is the force
m is the mass
a is the acceleration
In this problem, we have:
m = 70 kg is the mass
is the acceleration (which is negative, because it is a deceleration)
So, we can use the equation above to find the force:

and the negative sign simply means that the force is in the opposite direction to the motion.
<em><u>throwing a ball up initially has a lot of kinetic energy because it is moving upwards ( kinetic energy is energy which a body possesses by virtue of being in motion.) this all then get converted to gravitational potential energy, and for a moment it is stationary before it begins to fall again. by the time it has returned again, all the gravitational potential energy has turned back into kinetic.</u></em>
