Answer:
m₁ (R +ℓ/2) / /( m₁ + m₂ )
Explanation:
We shall consider centre of the club's head as origin .
The centre of mass of the rod attached with sphere will be away from the centre of sphere by a distance
= R + ℓ /2 and its mass is m₁
mass of sphere is m₂ and distance of its centre of mass from origin is zero
So required CM = m₁ x₁ + m₂ x₂ / ( m₁ + m₂ )
= m₁ (R + ℓ /2) + m₂ x 0 /( m₁ + m₂ )
= m₁ (R +ℓ/2) / /( m₁ + m₂ )
Answer:
The value is 
Explanation:
From the question we are told that
The mass of the lithium nucleus is 
The radius is 
The speed of the lithium nucleus is 
Given that the lithium nucleus is travelling in a circular path, the magnetic force will be equivalent to a centripetal force so

And ![F_C[tex] is centripetal force mathematically represented as [tex]F_C = \frac{m * v^2}{r}](https://tex.z-dn.net/?f=F_C%5Btex%5D%20is%20centripetal%20%20force%20mathematically%20represented%20as%20%3C%2Fp%3E%3Cp%3E%20%20%20%20%20%20%20%20%20%5Btex%5DF_C%20%3D%20%5Cfrac%7Bm%20%2A%20%20v%5E2%7D%7Br%7D)
So

=> ![F_B = F_C = \frac{9.9932*10^{-27} * [2.40*10^{7}]^2}{ 0.536}](https://tex.z-dn.net/?f=F_B%20%3D%20F_C%20%3D%20%5Cfrac%7B9.9932%2A10%5E%7B-27%7D%20%2A%20%5B2.40%2A10%5E%7B7%7D%5D%5E2%7D%7B%200.536%7D)
=> 
The levels of structural organization:
cell ---> tissue ---> organ ---> organ system ---> organism
A dog's eye would be an organ.
Answer:
13.5 J
Explanation:
mass of ball, m = 3 kg
maximum height, h = 2.8 m
initial speed, u = 8 m/ s
Angle of projection, θ
use the formula of maximum height


Sin θ = 0.926
θ = 67.8°
The velocity at maximum height is u Cosθ = 8 Cos 67.8 = 3 m/s
So, kinetic energy at maximum height

K = 0.5 x 3 x 3 x 3
K = 13.5 J
