Light travels at precisely <span>299,792,458 metres every second (abbreviated to 3 x 10^8 metres every second but let's be precise)
There are 60 seconds in every minute (</span><span>299 792 458 x 60 = 17,987,547,480m)
60 minutes in every hour (17,987,547,480 x 60 = 1,079,252,849,000m)
96 hours in 4 days (</span><span>1,079,252,849,000 x 96 = 10,360,827,350,000m)
</span><span>Now let's convert to km to make this number (slightly) more manageable
(</span>10,360,827,350,000 / 1000 = <span>103,608,273,500km)
</span>Light travels <span>103,608,273,500km in 4 days - that's the equivalent of going around the equator of the earth 813,124 times!</span><span>

Answer:
As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer. There are two basic types of waves: mechanical and electromagnetic

Answer:
The number of moles HBr = 0.001825
The concentration of Ca(OH)2 = 0.009125 M
Explanation:
Step 1: Data given
Volume of the Ca(OH)2 = 100.0 mL = 0.100 L
Molarity of HBr = 5.00 * 10^-2 M
Volume of HBR = 36.5 mL = 0.0365 L
Step 2: The balanced equation
Ca(OH)2 + 2HBr → CaBr2 + 2H2O
Step 3: Calculate molarity of Ca(OH) 2
b*Va* Ca = a * Vb*Cb
⇒with b = the coefficient of HBr = 2
⇒with Va = the volume of Ca(OH)2 = 0.100 L
⇒with ca = the concentration of Ca(OH)2 = TO BE DETERMINED
⇒with a = the coefficient of Ca(OH)2 = 1
⇒with Vb = the volume of HBr = 0.0365 L
⇒with Cb = the concentration of HBr = 5.00 * 10^-2 = 0.05 M
2 * 0.100 * Ca = 1 * 0.0365 * 0.05
Ca = (0.0365*0.05) / 0.200
Ca = 0.009125 M
Step 4: Calculate moles HBr
Moles HBr = concentration HBr * volume HBr
Moles HBr = 0.05 M * 0.0365 L
Moles HBr = 0.001825 moles
