➷ Astrology: It hasn't shown any clear effectiveness in studies and doesn't have any scientific validity.
Aromatherapy with essential oils: It is only backed with low quality studies that just demonstrate the placebo effect
Acupuncture: Lots of research suggests it is just the placebo effect so it has no scientific backing

The first step is to use the formula from Boyle's Law.
[(351 L)(1.0 atm)]/(181L) = 1.94 atm.
To determine the depth of the location where the diver was working, 1.94 is multiplied by 10. Therefore, the location of the underwater archaeological site is 19.4 meters below the surface.
It’s hydrosphere if it’s right lmk
Answer:
- The annual cost for electricity to power a lampost for 7.00 h per day with a 100 W incandescent bulb is $ 40.89.
- The annual cost for electricity to power the same lampost for the same time with an energy efficient 25 W fluorescent bulb is $ 10.22.
So, you can save $ 40.89 - $ 10.22 = $ 30.67 per each lampost if you replace the incadescent bulb with the energy efficient fluorescent bulb.
Explanation:
kW.h means kilowatt.hour and is a unit of energy derived from the definition of power.
The definition of power is energy per time:
Thus, you get:
For the units, you get:
- [Energy] = [Power] [time] = KW.h.
<u>1. Calculate the energy used by the 100 W incandescent light bulb that is used 7.00 h per day, in a year (365 days).</u>
- E = Power × time = 100 W × 7.00 h / day × 365 day / year × 24 h= 255,500 W.h/year
- Divide by 1,000 to convert to kW: 255.5 kW.h/year
<u />
<u>2. Calculate the energy used by the 25 W flourescent bulb:</u>
- E = 25 W × 7.00 h / day × 365 day / year × 24 h= 63,875 W.h/year
- Divide by 1,000 to convert to kW: 63.875 kW.h/year
<u>3. Now, you can calculate both costs:</u>
- Cost per year = cost per kW.h times number of kW.h per year
<u>100 W bulb:</u>
<u />
- $ 0.16/ kW.h × 255.55 kW.h/ year = $ 40.89 / year
<u>25 W bulb:</u>
- $ 0.16/ kW.h × 63.875 kW.h/ year = $ 10.22 / year
