Answer:
I don't know if it's correct but my answer is "5.14"
The Answer:
The diameter will be reduced or shorten to prevent the induced current in the metal loop
explanation:
Magnetic flux is given as
Φ = BA•Cosθ
Since the angle is kept constant.
So to have same magnetic flux with larger magnetic field required only the diameter to changed
From the equation above,
Φ = BA•Cosθ
B= Φ / A•Cosθ
Since both Flux and the angle is constant
Then, The magnetic field is inversely proportional to the Area
And the areas is a function of diameter, Area = πd²/4
So to have a larger magnetic field, we need to reduce or shorten the diameter.
As d reduces, B increases.
B.) They have no effect on air temperature over land on the coast.
Explanation:
The statement that ocean surface currents do not have any effect on air temperature over land on the coast is very incorrect.
In fact, ocean surface currents shapes the coast a whole lot.
- There is a constant interaction between the ocean surface current and the air masses on land.
- They interact by simple convection through which heat is transferred from one point to the other.
- During the day, air masses moves from the land to the ocean because air around the coast are hotter and less dense.
- They are quickly replaced by colder and less denser air from the ocean.
- At night the reverse is the case.

The three things that can affect a condition to enforce a slide is friction, weight, and slope of an area. Solutions that can make flow easily are those that can create less friction depending on the condition of an environment where it is present. Some of these materials are water, oil, and dense liquids.
For this problem the formula you need is below.
Rate Time = Distance
What you're asking is what the rate of the car was, so to do that, we must plug! (Rate will be represented by “x”)
First, we need to find out how many hours is 2 hours and 24 minutes. If there are 60 minutes in an hour, then we can just say 24 minutes is 24/60 or 2/5 hours. So 2 hours and 24 minutes equals 2.4 hours. Now we plug:
2.4x = 200
Then we divide both sides by 2.4:
2.4x/2.4 = 200/2.4
x = 83.33 kilometers per hour. is the answer
Hope this helps!
