Julie wanted to know if adding calcium fertilizer to tomato plants will help prevent a disease of tomato plants called blossom-e

nd rot. She used 10 tomato plants. She put 5 plants in a sunny part of the garden and gave each one calcium fertilizer once a week. She placed the other 5 plants in a shady part of the garden and gave them calcium fertilizer twice a week—she thought that since they were in the shade they might need more fertilizer. She then observed the 10 plants for 3 months to see if the fertilizer helped prevent blossom-end rot. Identify and explain one weakness in Julie's experimental design.

The alpha line in the balmer series of the hydrogen spectrum consists of light having a wavelength of 6.56. calculate the freque
guajiro [1.7K]
The alpha line in the Balmer series is the transition from n=3 to n=2 and with the wavelength of λ=656 nm = 6.56*10^-7 m. To get the frequency we need the formula: v=λ*f where v is the speed of light, λ is the wavelength and f is the frequency, or c=λ*f. c=3*10^8 m/s. To get the frequency: f=c/λ. Now we input the numbers: f=(3*10^8)/(6.56*10^-7)=4.57*10^14 Hz. So the frequency of the light from alpha line is f= 4.57*10^14 Hz.

You can comfortably hold your fingers close beside a candle flame, but not very close above the flame. why? challenge (optional)
Inessa05 [86]
The candle flame releases hot gases, which directly go in upwards directions. Due to which the air near the flame of the candle is very hot and dense. The particles along with vapour move up. And since the sideways, the air is not very dense and hot, we are able to hold the candle. In anti-gravity region, there will be no density differences and also, the convection process wont occur. So, the candle quickly snuffs off.
