As the box sits at the top of an incline that is 50.0 cm tall and makes an angle of 25° with the ground, The time it takes to reach the bottom of the incline is mathematically given as
t=0.148s
<h3>What is the time it takes the box to reach the bottom of the incline?</h3>
Generally, the equation for the acceleration is mathematically given as
Therefore
a=(9.8sin-(0.15cos35))
a=4.417
Thereofore
v^2=v0^2+2al
v=2.6533
In conclusion, The time t is
t=v-v0/a
2.65-20/4.417
t=0.148s

Answer:
n = 3
Solution:
Since, the slit used is same and hence slit distance 'x' will also be same.
Also, the wavelengths coincide, will also be same.
Using Bragg's eqn for both the wavelengths:
(1)
(2)
equate eqn (1) and (2):
n = 3
Extinct<span> might be a word you associate with animals that lived long ago, like the dinosaurs, but did you know that over 18,000 species are classified as "threatened" (susceptible to extinction) today? Scientists involved in wildlife conservation have a tough job; they are in charge of determining what needs to be done to prevent a species from becoming extinct. Habitat, food supply, and impacts of local human populations are just a few of the factors these scientists take into account. It is a lot to keep track of for a single location, but the job becomes even harder when it is a migratory animal. In this science project, you will get a firsthand look at their job. You will access </span>real<span> data about migratory birds and use satellite images to analyze their habitats, then come up with a conservation plan to protect the species from extinction.</span>
Boyle's law states that the volume of a given mass of gas is inversely proportional to the pressure provided that the temperature remains constant.
Charle's law states that the volume of a given mass of gas is directly proportional to temperature provided that the pressur remains constant.
