Answer:
The wavelength is
The frequency is
Explanation:
Given that,
Distance between slits d= 0.044 mm
Distance between fringe and center of the pattern y= 8.1 cm
Distance between slits and fringes D = 6.40 m
We need to calculate the wavelength
For constructive interference
Put the value into the formula
We need to calculate the frequency
Using formula of frequency
Hence, The wavelength is
The frequency is
Answer:
991.67 miles per day
Explanation:
Since it travels 2975 miles per day, distance traveled in a day =2975/3=991.67 miles
1 watt means 1 joule of energy per second
The food processor uses 1,150 joules of energy per second.
The blade uses 950 joules per second to slice, dice, and puree.
The rest of the energy goes to heat the appliance's motor, or
overcome friction in the blade's bearings, etc. How much energy
does NOT go into slicing and pureeing ?
(1,150 watts) - (950 watts) = 200 joules per second
1 minute = 60 seconds
2 minutes = 120 seconds
Energy wasted in 2 minutes =
(200 joules/second) x (120 seconds) = <em>24,000 joules</em>
That's enough energy to operate a 34-watt CFL (curly) light bulb
for 11 minutes 46 seconds.
I think the word would be increases. I don't know what the options are though.
The answer is C
All other statements are correct but C
