Answer:
The two carts will experience an impulse of the same magnitude, but of opposite directions.
Explanation:
Newton's third law proves that though action and reaction are the same, but they are opposite to each other.
i.e = -
where: and have equal value.
Impulse = F x t
where F is the force on the object and t is the time of impact.
In the given question, since the collision takes place in a given time.
Then;
x = - x
⇒ = -
Thus, since the sum of the forces acting on the system are zero, then the two carts experience an impulse of the same magnitude but opposite in directions.
Answer:
current

.....is the correct answer
The total current through the circuit is 0. 19A
<h3>How to determine the current</h3>
We have the formula for power to be;
Current, I = V/R
Voltage = 7. 7V
Resistance in parallel = R1R2/ R1 + r2
Resistance in parallel = = = 41. 40 Ohms
Current = = 0. 19 A
Thus, the total current through the circuit is 0. 19A

We can certainly draw water into our lungs, even though
our brain screams "Don't do that !".
But our lungs can only separate oxygen out of air, not out of
water. So if there's only water in our lungs, we pass out after
a short time because we're not getting any oxygen.
