Bailey wants to find out which frozen solid melts the fastest: soda, ice, or orange juice. She pours each of the three liquids into the empty cubes of an ice tray, and then places the ice tray in the freezer overnight. The next day, she pulls the ice tray out and sets each cube on its own plate. She then waits and watches for them to melt. When the last part of the frozen liquid melts, she records the time.

An underwater sound source emits waves of frequency 30 kHz in all directions. How does the intensity of the waves (in Watts/m2) vary with distance r from the source?a) 1/r^3
b) 1/r^2
c) 1/r
d) None of above

Answers

When an underwater sound source emits waves of frequency 30 kHz in all directions, the intensity of the waves (in Watts/m2) vary with distance r from the source by the relation 1/r²

As the intensity mechanical sound wave is inversely proportional to the square of the distance from the source, therefore the correct option is B.

What is the Wavelength?

Wavelength can be understood in terms of the distance between any two similar successive points across any wave for example wavelength can be calculated by measuring the distance between any two successive crests.

It is the total length of the wave for which it completes one cycle.

The intensity of a mechanical wave is inversely proportional to the square of the distance from the source.

Part of your electrical load is a 60-W light that is on continuously. By what percentage can your energy consumption be reduced by turning this light off

Answers

Answer:

Following are the solution to the given question:

Explanation:

Please find the complete question in the attached file.

The cost after 30 days is 60 dollars. As energy remains constant, the cost per hour over 30 days will be decreased.

\to (\$60)/((30 \ days)/(24\ hours)) = \$0.08 / kwh.

Thus, (\$0.08)/(\$0.12) = 0.694 \ kW *  0.694 \ kW  * 1000 = 694 \ W.

The electricity used is continuously 694W over 30 days.

If just resistor loads (no reagents) were assumed,

\to I = (P)/(V)= (694\ W)/(120\ V) = 5.78\ A

Energy usage reduction percentage = ((60\ W)/(694\ W) * 100\%)

This bulb accounts for 8.64\% of the energy used, hence it saves when you switch it off.

A certain part of the electromagnetic spectrum ranges from 200 nm to 400 nm. What is the lowest frequency associated with this portion of the spectrum?

Answers

Answer:

the lowest frequency is 7.5* 10^(14) Hz

Explanation:

In the question it is given that wavelength(L) in the range of 200μm to 400μm.

let ν be frequency of wave v velocity = 3\times 10^8

velocity v= Lν

therefore ν=(v)/(L)

frequency ν be lopwest when L will be heighest

ν(lowest)=(3* 10^8)/(400* 10^-9)

ν=7.5* 10^(14) Hz
