Answer:
Explanation:
<u>Force Constant of a Spring</u>
The force F applied to a spring produces a stretching distance x. These variables are linearly related as expressed by Hook's law:
If we could measure the distance a spring stretches when applying a known force, we'd be able to find the value of K. The experiment stated in the question places some mass of a known weight of 96 N that produced a stretching distance of 16 m. Knowing both variables, we can solve the above equation for K
Answer:
Explanation:
Snell's law for index of refraction of a medium is as follows .
sin i / sin r = μ
i is angle of incidence , r is angle of refraction and μ is refractive index.
sin r = sin i / μ .
As μ for blue light is greatest , angle of refraction for blue light will be least . Similarly , angle of refraction will be maximum for red light .
So maximum deviation in the direction of light will occur in blue light due to least angle of refraction because
deviation angle = angle of incidence - angle of refraction .
So the order of light from inward towards surface
= blue , green , red .
Answer:
Tangential speed = 5.72 m/s
Centripetal acceleration = 
Explanation:
The tangential speed, V, is given by
where 
is the angular speed and is given by 
(f is the angular frequency or frequency of rotation)
Thus,
The centripetal acceleration,a, is given by
It would be "Double replacement".
Hope this helps!
Its a very syplel thing devipe it by distance and boom u shude have it
