Explanation:When any living organism gets thrown off balance, its body or cells help it return to normal. In other words, living organisms have the ability to keep a stable internal environment. Maintaining a balance inside the body or cells of organisms is known as homeostasis.
The moment of inertia of the system about an axis through the center of the square, perpendicular to its plane is .
Given data:
The mass of each sphere is, .
Length of side of square is, .
The expression for the moment of inertia of the system about an axis through the center of the square, perpendicular to its plane is,
Here,
R is the distance between center of the square and the sphere. And its value is,
Then, moment of inertia is,
Thus, the moment of inertia of the system about an axis through the center of the square, perpendicular to its plane is .

The moment of inertia of the system about an axis through the center of the square, perpendicular to the plane is 0.064 kg.m²
Let's recall Moment of Inertia formula as follows:
where:
I = moment of inertia
m = mass of object
R = distance between the object and the axis of rotation.
Given:
mass of sphere = m = 0.200 kg
length of side = x = 0.400 m
Asked:
net moment of inertia = ΣI = ?
Solution:
Let's ilustrate this question as shown in the attachment.
Firstly , let's find distance between center of the square and the sphere:
Next , we could find total moment of inertia as follows:

the answer is a battery
Answer:
(a) 200.0628 N ; ( b) 4.08Kg
Explanation:
We know,
w = mg [here w= weight , m= mass , g= gravity]
now,
gravity on earth (g) =9.807 m/s²
mass of the spanner (m)=?
weight of the spanner on earth(w) = 40N
⇒ w = 40N
⇒m g =40N
⇒m = (40/g) Kg
⇒m= (40/9.807)Kg
∴m=4.08Kg
∴mass of the spanner on earth = 4.08Kg
We know,
Mass is the amount of matter in an object . Somass will remain same both on earth and jupiter.
So,
(b)The mass of the spanner on jupiter = 4.08Kg
Now,
The mass of the spanner on jupitar (m) = 4.08Kg
Gravity on jupiter (g*) = 5.g [5 times on earth]
= 5 . (9.807)m/s²
=49.035 m/s²
(a)
∴weight of the spanner on jupitar(w*) = m g*
=(4.08 x 49.035) N
=200.0628 N
