What is the output voltage from a step up transformer with 25 turns in the primary coil and 75 turns in the secondary coil if th

Greeley [361]

Answer:

360 V

Explanation:

We can use the transformer equation:

$\frac{V_p}{N_p}=\frac{V_s}{N_s}$

where

$V_p$ is the primary (input) voltage

$N_p$ is the number of turns in the primary coil

$V_s$ is the secondary (output) voltage

$N_s$ is the number of turns in the secondary coil

In this problem,

$V_p = 120 V\\N_p = 25\\N_s = 75$

Substituting into the equation, we can find the output voltage:

$V_s = N_s \frac{V_p}{N_p}=(75)\frac{120}{25}=360 V$

Two UFPD are patrolling the campus on foot. To cover more ground, they split up and begin walking in different directions. Offic

miss Akunina [59]

Answer:

0.256 hours

Explanation:

<u>Vectors in the plane </u>

We know Office A is walking at 5 mph directly south. Let $X_A$ be its distance. In t hours he has walked

$X_A=5t\ \text{miles}$

Office B is walking at 6 mph directly west. In t hours his distance is

$X_B=6t\ \text{miles}$

Since both directions are 90 degrees apart, the distance between them is the hypotenuse of a triangle which sides are the distances of each office

$D=\sqrt{X_A^2+X_B^2}$

$D=\sqrt{(5t)^2+(6t)^2}$

$D=\sqrt{61}t$

This distance is known to be 2 miles, so

$\sqrt{61}t=2$

$t =\frac{2}{\sqrt{61}}=0.256\ hours$

t is approximately 15 minutes

If you were trying to kill a fish witha a spear, woukd you ain where you see the fish?

patriot [66]

No, you can't aim where you see the fish, because refraction will change the position of the fish and make it appear in a different position from where it actually is.

Hope this helps!
