A circular-motion addict of mass 83.0 kg rides a Ferris wheel around in a vertical circle of radius 13.0 m at a constant speed o
Svetllana [295]

Answer:

(A) Time period T = 6.28 SEC

(B) At highest point fore is - 575.83 N

(B) At lowest point force is 1050.97 N      

Explanation:

We have given that mass m = 83 kg

Radius r = 13 m

Speed v = 6.10 m/sec

(A) Time period of the motion is given by T=\frac{2\pi r}{v}=\frac{2\times 3.14\times 13}{6.10}=6.28sec

(b) Net force is given by F_{NET}=\frac{mv^2}{r}=\frac{83\times 6.10^2}{13}=237.571N

Force due to gravity F_{gravity}=mg=83\times 9.8=813.4N

At highest point F_{NORMAL}=F_{NET}-F_{GRAVITY}=237.57-813.4=-575.83

(B) At lowest point F_{NORMAL}=F_{NET}+F_{GRAVITY}=237.57+813.4=1050.97N

Determine the values of m and n when the following mass of the Earth is written in scientific notation: 5,970,000,000,000,000,00
yuradex [85]

Explanation:

Mass of the Earth is equal to,

m=5,970,000,000,000,000,000,000,000\ kg

Any number can be written in the form of scientific notation as :

N=m\times 10^n

m is the real number

n is any integer

Mass of the earth can be written in the form of scientific notation as :

m=5.97\times 10^{24}\ m

Here,

m = 5.97

n = 24

Hence, this is the required solution.
