Answer:
Secondary current is 8A
Explanation:
Data :
Primary supply = Vp = 240 V
Secondary supply = Vs = 60V
Primary current = Ip = 2A
Secondary current = Is = ?
Formula : Vp × Ip = Vs × Is
So for secondary current formula becomes
Is = (Vp/Vs)×Ip = (240/60) × 2
Is = 4 × 2 = 8A
Average velocity over a given time interval is the distance traveled divided by the time:
Answer:
The relation is n = c/v where c is speed of light in a vacuum....v is the speed of light in the new medium ......n is the refractive index of the material
Answer:
The kite string is feet long.
Explanation:
Use the Pythagorean Theorem, which is .
Here the question is asking for , which would be the hypotenuse, or the longest side of the triangle.
So the would be , and the would be .
Plug those values into the formula, and that would get .
Now, solve for , which would equal .
That means we would have to solve for .
Square root both sides of the equation, getting .
Solve for , which would get us .
Hence, the answer to this would question would be .
