The voltage of an electrical unit is multiplied
Kay [80]
<span>The unit for potential energy per unit charge, or voltage, is the volt, which has the symbol "V." It takes its name from the Italian physicist Alessandro Volta, credited with inventing one of the first electric batteries.Voltage refers to the work that would be necessary for each unit charge against the existing electric field to move a charge from Point A to Point B. One volt is the equivalent of multiplying one ampere (a unit of current) by one ohm (a unit of resistance). To get the power in terms of watts, it is necessary to multiply the voltage by the current in amps.</span>

A cruise ship is traveling at a speed of 20 knots. A knot is aproxamatley equal to 1.151 miles per hour what is the approximate
algol13

20 knots * 1.151 = 23.02 miles per hour  There are 1,760 yards in a mile and 3,600 seconds in an hour.  So, we multiply 23.02 * (1,760 / 3,600) which equals

11.2542222222 yards / second

Three numbers are in ratio 2:5:7. <br> The middle number is 75. What are the other two numbers?
Tatiana [17]

Answer:

First number - 30

Second number - 105

Step-by-step explanation:

2/5 of 75 would be 30, so it is the answer.

7/5 of 75 would be 105, so it is the answer.

This is how you would solve this problem.

Find the exact values of the remaining five trigonometric functions of theta, suppose theta is an angle in the standard position
nexus9112 [7]

Answer:

\sin(\theta)=60/61\text{ and } \csc(\theta)=61/60\\\cos(\theta)=11/61\text{ and } \sec(\theta)=61/11\\\tan(\theta)=60/11\text{ and } \cot(\theta)=11/60

Step-by-step explanation:

So, we know that:

\tan(\theta)=60/11\text{ and } 90\textdegree

Since θ is in QI, this means that <em>all</em> of our trig ratios will be positive. Recall All Students Take Calculus. Since it's QI, we refer to A in All. The A tells us that all the ratios will be positive.

Now, let's figure out the remaining ratios knowing that all of them is positive. First, let's find the hypotenuse. Recall that tangent is the ratio of the <em>opposite side to the adjacent side</em>. So, we can use the Pythagorean Theorem to find the hypotenuse. So:

a^2+b^2=c^2

Substitute 60 for a and 11 for b:

60^2+11^2=c^2

Solve for c. Square both numbers:

3600+121=c^2

Add:

c^2=3721

Take the square root of both sides:

c=61

Therefore, the hypotenuse is 61.

So, our side lengths are: Opposite=60; Adjacent=11; and Hypotenuse=61.

Now that we know the lengths, we can find the other trig ratios:

Sine and Cosecant:

\sin(\theta)=opp/hyp

Substitute 60 for Opp and 61 for Hyp:

\sin(\theta)=60/61

Cosecant is the reciprocal of sine. So:

\csc(\theta)=61/60

Cosine and Secant:

\cos(\theta)=adj/hyp

Substitute 11 for Adj and 61 for Hyp:

\cos(\theta)=11/61

Secant is the reciprocal of cosine. So:

\sec(\theta)=61/11

Tangent and Cotangent:

We are already given that tangent is:

\tan(\theta)=60/11

Cotangent is the reciprocal of tangent. So:

\cot(\theta)=11/60
