Answer:
fem = -A β
Explanation:
Faraday's law gives the induced electromotive source (emf)
fem =
the magnetic flux is
= B. A = B A cos θ
the bold are vectros. In this case the normal to the ring is parallel to the magnetic field so the angle is zero cos 0 = 1, also the area of the ring is constant
fem = -A
we carry out the derivative of the function B = α + β t
fem = -A β
so we see that there is an electromotive force in the ring.
Answer:
Explanation:
ASSUMING the defender at 5 m is NOT the goalie.
the ball horizontal velocity is 5 m/0.5 s = 10 m/s
The goalie, presumably at the goal line, has 15 m / 10 m/s = 1.5 s to react and move to the ball position.
Must be little league soccer as 10 m/s is a rather wimpy soccer ball speed.
Answer: If the balloon acquires charge, Sam's hair loses charge.

I JUST GOT THIS QUESTION RIGHT ON THE IA4 <3
Answer:
I hope this helps and I'm not to late
A way the balls behave the same way is by bouncing about 1 time after throwing the balls up. A way the balls act differently is the blue ball is bouncier than all the balls, the red ball bounces about 2 times before stopping, and the green ball doesn’t really bounce except for one time.
Explanation:
you also can use paraphrase to help you reword bye bye!!
Both countries will have the same advantage in producing goods.
<h3>What does the theory of comparative advantage state?</h3>
According to the theory of comparative advantage, a person should participate in an economic activity in which they have a comparative advantage, i.e., in which they are more effective than in the other activity. In terms of economies, they should engage in the production of those commodities and services at which they are better placed than the other.
<h3>Which country will have the comparative advantage in producing capital goods?</h3>
The output potential, resource level, and technological level of two nations A and B are identical. This suggests that both countries A and B are producing at the same level and that neither one is doing better than the other in terms of production.
