Answer:
The wavelength is 503 nm
Explanation:
Considering constructive interference , this means that route(path) difference is equal to the product of order of fringe and wavelength of the light
i.e dsinθ = m
Where is the wavelength of light and m is the order of the fringe
Looking at θ to be very small , sin θ can be approximated to θ
and
Substituting this into the above equation
making x the subject
This above equation will give the value of the distance of the order fringe of the wavelength from the central fringe
Replacing with the value given in the question we have
= 710 nm m = 2 d =0.66 mm , l = 2.0 m
The separation of the second fringe from central maximum is 4,303 mm
To obtain the separation of the second order fringe of the unknown light from central maximum
Now to obtain the wavelength of this second source
from
Now substituting 3,053 mm for 2.0 mm for l , 0.66 mm for d and 2 for m in the above formula
Answer:
Explanation:
The acceleration of an object can be calculated by using Newton's second law:
where
F is the net force applied on the object
m is the mass of the object
a is its acceleration
In this problem, we have F=125 N and m=25.0 kg, so we can rearrange the equation to calculate the acceleration:
Answer:
Animal 1 because it takes 3s to go 25 meters 3.5s to go 50 meters and 5s to go 75 meters while the others take longer.

i feel a kinda sharp out of breth feeling everytime i breath. my liver hurts when i breath too. even just running up my staircase(or walking) im outta breath. please help my parents wont take me to the doctor and i need to know whats wrong. im foreal like really fit tho
It's true
work measure by joule.
Energy = work/time
= joule/s .
and joule/s represents watt
