This is a not a calculator problem, it's a physics problem. You need the formula: E = hf, where f is the frequency and h is "Planck's constant" (6.626068 x 10^-34 m^2kg/sec).

On your calculator, punch in 3.0 [EE] 12 [x] 6.63 [EE] -34 to get the answer.

Hi,
A 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
The service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
Good luck!

### I have a alpine 6013 sub, what should i tune the port to? i listen to mostly rap if that makes a difference.

Box should be 1.2 cubic feet. port should be 13 square inches depth 16 inches and Fb/F3 will be 42/35 (Fb=port freq F3=cut-off freq

### What is the frequency (in MegaHertz) of radiation whose energy is 5.84E-29 kJ?

The connection is Planck's Constant, which expresses the proportionality or ratio between the energy of a photon and its frequency.

E = hf

where h is Planck's Constant (actually frequency is usually represented by the Greek letter nu, but that will not reproduce here)

5.84 x 10^3 x 10^ -29 = 6.626 x 10^ -34 x f

f = 8.814 x 10^7 Hz or 88.14 MHz

which is about Ch 6 in the VHF TV spectrum

### Kicker dx 250.1 class d monoblock amp has a fixed lpf at 80 hz 24db octave non adjustable. My car stereo is a pioneer deh-x55hd with the sub control set at 100 hz -6 slope unable to turn sub control off to...

Do you have the subwoofer amp connected to the pioneer thru pre amp connections; pre amp output of pioneer to pre amp input of Kicker amp. Page 10 of the manual explains how to adjust the subwoofer output. You can select the cutoff freq. that will pass to the subwoofer; The slopes don't match perfectly, but if you use the -12 slope , it should work fine.
Cut-off frequency:
50HZ

63HZ

### Out of Range

Your horizontal should be between 30k-80khz while vertical should be 50-75 hz. So you are definitely too high. I would check supply voltages and open it up and look for any obvious issues with capacitors.

### The time falls back by about 10 mins a hour? I am using it in India with a 230/110 adapter but working at 50 Hz instead of 60 Hz Is the timing derived from supply freq? i don't think so but just asking ...

The frequency of the power supply line IS where the clock obtains it's reference...it is divided internally to provide the timing for the microprocessor...the only way to make it work properly to my knowledge is to plug into 60 hz supply.

### I purchase a microwave which is 240v 50z but in my country we usually use 230v 60hz, can i use AVR to solve my problem?

Hi. An AVR (auto voltage regulator) will not change the freqs from 50 Hz to 60 Hz. An AVR only changes voltage. The frequency in is the same frequency out.

Having said that.... I don't think your going to damage your unit as long as you don't run it for long periods time. I live in the tropics and use 4 different AVRs myself. I have had both 50z and 60 hz electronics and appliances running fine on 60 Hz for the last 7 years. Your call! Hopefully this was useful information.

### Facial redness..

The heat you are feeling is from infrared photons. The type of photons that damages skin is mainly ultraviolet photons, which are much higher in energy than that of IR photons. Your skin may become pink from the heat but actual damage is unlikely at such lower energy for IR photons. In other words, you are not going to get a suntan. dont worry about it.

### Scanner(POLICE) Question

Hi, using the manual button, step to channel 1 and enter your freq. including the point then press the E button. You might have to step to the next channel using the manual button again. Enter the next freq. and repeat. WX is the weather bands. Lockout is for locking out a nuisance channel(as an example, if someone's mic stays keyed, and keeps the squelch open).Priority is for any channel whose conversations you don't want to miss, just press the button for the specific channel. That way any time someone keys up on your priority channel, even if it's on another channel talking, will go right to the priority one. Review gives you a readout of the freq you programmed into a specific channel. If you need new or extra freq's check here on this site.
