Answer:
Answer:
I. The hollow sphere has the greater angular momentum.
Explanation:
Given that the mass and radius of hollow sphere and solid sphere are same. Let the mass and radius of two spheres be m and r respectively. The two spheres are rotating having same angular velocity ω .
Moment of inertia of solid sphere, I₁ =
Moment of inertia of hollow sphere, I₂ =
Since, I₁ and I₂ are not equal. Therefore, the statement iv is wrong.
The relation between angular momentum, moment of inertia and angular velocity is :
L = Iω
Let L₁ and L₂ be the angular momentum of solid sphere and hollow sphere respectively.
L₁ = I₁ω and L₂ = I₂ω
As ω is same for both spheres but I₂ is greater than I₁, hence L₂ is greater than L₁.
Therefore, statement I is correct that the hollow sphere has the greater angular momentum.
Explanation:
(total mark/number of subjects)×100=63
(total mark+20+2)/(number of subjects)×100=65
(total mark+22)/number of subjects=0.65
let n be the total number of subjects
((0.63 of 100n)+22)÷(100n)=0.65
because he obtained only 63 percent from sum of all marks.(marks counted from 100)
(0.63×100n+22)÷(100n)=0.65
0.63+(22÷100n)=0.65
0.22÷n=0.65-0.63
0.22÷n=0.02
n=0.22/0.02
n=11
there were 11 subjects
