Answer:
536.56 m/s
Explanation:
We'll begin by calculating the momentum of the Porsche. This can be obtained as follow:
Mass (m) of Porsche = 1361 kg
Velocity (v) of Porsche = 26.82 m/s
Momentum of Porsche =?
Momentum = mass × velocity
Momentum = 1361 × 26.82
Momentum of Porsche = 36502.02 Kgm/s
Finally, we shall determine the velocity you need to be running with in order to have the same momentum as the Porsche. This can be obtained as follow:
Your Mass = 68.03 kg
Your Momentum = Momentum of Porsche = 36502.02 Kgm/s
Your velocity =?
Momentum = mass × velocity
36502.02 = 68.03 × velocity
Divide both side by 68.03
Velocity = 36502.02 / 68.03
Velocity = 536.56 m/s
Thus you must be running with a speed of 536.56 m/s in order to have the same momentum as Porsche.
D. All the three bulbs connected in the series circuit will burn at equal brightness.
<h3>What is series circuit?</h3>
A series circuit comprises a path along which the whole current flows through each component.
A parallel circuit comprises branches so that the current divides and only part of it flows through any branch.
In a series circuit, same current flows in each component of the circuit.
V = I(R₁ + R₂ + R₃)
where;
- R₁ is resistance of bulb 1
- R₂ is resistance of bulb 2
- R₃ is resistance of bulb 3
If all the bulbs have equal resistance, they will burn at equal brightness.
Thus, all the three bulbs connected in the series circuit will burn at equal brightness.
The correct option is D.

I think it is (3) 690 N. You can use the theorem of Impulse and momentum where the impulse is equal to the change in momentum or:
(where f is for final and i for initial).
So you get:
Answer: Earth's magnetic field has flipped its polarity many times over the ... Earth has settled in the last 20 million years into a pattern of a pole reversal about ... And while reversals have happened more frequently in "recent" years, when ... per year, as opposed to about 10 miles per year in the early 20th century.
