Phoenix [80]3 years ago
5 0
I once had to create a water ripple experiment. I took a tote covered the bottom with rocks then filled the tote half way full with water. i made a ramp out of a shoebox or similar and took a bouncy ball and rolled it down the ramp. The thing I should have done is have something so you could tell how strong the wave was.

I don't know if your teacher would take this When I did it we were talking about natural disasters so ask your teacher first!

A transformer with 1000 turns on the primary coil is used to decrease the voltage from 2500 V to 120 V for home use. How many tu
Katyanochek1 [597]

Answer:

The number of turns in the secondary coil is 48.

(B) is correct option.

Explanation:

Given that,

Number of turns on primary coil= 1000

Primary voltage = 2500 V

Secondary voltage = 120 v

We need to calculate the turns  in the secondary coil

Using relation between voltage and number of turns in primary and secondary coil

\dfrac{V_{s}}{V_{p}}=\dfrac{N_{s}}{N_{p}}

Put the value into the formula

\dfrac{120}{2500}=\dfrac{N_{s}}{1000}

N_{s}=\dfrac{120}{2500}\times1000

N_{s}=48\ turns

Hence, The number of turns in the secondary coil is 48.

Solve the problem using dimensional analysis. Every number must have a unit. Work must be shown. Conversion factors are in the t
anygoal [31]

The number of grams of gold you can purchase for $15 if Gold cost $8.00 per ounce is 53.26g

Dimensional analysis is a means of representing values using units.

From the question, we are told that Gold cost $8.00 per ounce, this means that:

$8.00 = 1 ounce

In order to calculate the amount in grams you can purchase for $15, we need to know the price in ounces first.

$15.00 = x

Divide both expressions

\dfrac{8}{15} = \dfrac{1}{x}\\x = \dfrac{15}{8}\\x=  1.875 ounces

Next is to convert the ounces to pounds.

1 pound = 16 ounces

y = 1.875 ounces

y = 1.875/16

y = 0.1171875 pounds

Conver 0.1171875 pounds to kg

Since 1kg = 2.2 pounds

z = 0.1171875 pounds

2.2z = 0.1171875

z = 0.1171875/2.2

z = 0.053267kg

Finally, convert 0.053267kg to grams using the conversion rate

1kg = 1000g

0.053267kg = y

y =  0.05326 * 1000

y = 53.26g

This shows that the amount of grams you can purchase for $15 is 53.26g
