You can write the equation in 3 different ways, depending on which quantity you want to be the dependent variable. Any one of the three forms can be derived from either of the other two with a simple algebra operation. They're all the same relationship, described by "Ohm's Law".
==> Current = (potential difference) / (resistance)
==> Potential difference = (current) x (resistance)
==> Resistance = (potential difference) / (resistance)
Answer:
192Ns
Explanation:
The following were obtained from the question:
M = 2kg
F = 8N
t = 24secs
Impulse =?
Impulse = Ft
Impulse = 8 x 24 = 192Ns
Total rate at which electrical energy is dissipated by the two resistors are V²/R or I²R.
<u>Explanation:</u>
When the two resistors are combined in series then the total resistance gets added.
If 
and 
are in series then total resistance, R =
Total resistance becomes + 19 Ω
The total electrical power dissipated is equivalent to the power dissipated.
We know,
Power = V²/R or
Power = I²R
where, V is the potential difference between the ends
I is the current supplied.
Therefore, total speed at which electrical power is consumed by the two resistors are V²/R or I²R.

Answer: A) 3 pronged cord</h3>
Explanation:
One prong is known as the hot wire, where the electricity comes in, while the second prong is the neutral wire and electricity leaves. Recall that a circuit must be made for electrons to flow. This means that electrons enters your house through the transmission wires and then the electrons leave along the same lines they entered (just along a different wire).
This set up describes a 2 pronged cord. Adding a third prong allows for a grounding to happen. In the event of an electrical surge, when too many electrons are flowing, disaster is likely to happen without some kind of safety features. The grounding prong allows electrons to seek the ground. You can think of it like a drain in a bathtub when too much water gets in the tub.
