Answer:
n = 1.523
Explanation:
Snell's law
1.273sin32.89 = nsin26.99
To find the relative frequencies, divide each frequency by the total number of throws - in this case, 100.
Red: 10/100=1/10=0.1
Yellow:35/100=0.35
Blue:48/100= 0.48
Misses: 7/100=0.07
The event of landing in the red region has a relative frequency of 0.1 which means the dart landed in the red region about 10% (0.1 x 100%) of the time.
Derive relation F = ma from Newton 2nd Law of Motion. Let us derive the relation of force F = ma from Newton's second law: ... It means that the linear momentum will change faster when a bigger force is applied. Consider a body of mass 'm' moving with velocity v.
It is a scaler because it’s only fully describes by a magnitude and a numerical alone
Answer:
d. 6/5 M.
Explanation:
let the angular velocity = 
the radius of sphere (r) = 
moment of inertia of solid sphere 
= 
rotational K.E of solid sphere= 
= 
we represent the mass of hallow sphere= 
moment of inertia of solid sphere
= 
rotational K.E of hollow sphere= 
= 
NOW,the kinetic energy of solid sphere= 1/2 kinetic energy of hallow sphere
=![1/2 [2/5 M(D/2)^2 ]\omega^2= 1/2 (1/2 (2/3 M_{hs}(D/2)^2 )\omega^2 }](https://tex.z-dn.net/?f=1%2F2%20%5B2%2F5%20M%28D%2F2%29%5E2%20%5D%5Comega%5E2%3D%201%2F2%20%281%2F2%20%282%2F3%20M_%7Bhs%7D%28D%2F2%29%5E2%20%29%5Comega%5E2%20%7D)
2/5M= 1/3
= 3(2/5M)
= 6/5 M
