Answer: option A: What is the proper number of children to have in today's family?

A scientific investigation includes a scientific method to approach a problem. There is a systematic approach is used to address a problem. It generally includes five steps: first a problem needs to be identified. Thereafter, a background research is important to form a hypothesis. Fourthly, an experiment, observation or measurements are done in order to draw conclusions at last.

From the given questions, option A is a question which cannot be scientifically investigated. This is because, it varies from individual to society to the economy of a state. The conclusion would not be generalized solution.

option B.Will equal sizes of Styrofoam and wood have the same mass? can be scientifically investigated. The given quantities can be measured and tested.

C. Does adding salt to water raise its boiling point? This can be scientifically tested

D. Does lack of sunlight affect plant growth? This can also be scientifically measured.

The moment of inertia of a thin uniform rod of mass M and length L about an Axis perpendicular to the rod through its Centre is

sleet_krkn [62]

Answer:

I = I₀ + M(L/2)²

Explanation:

Given that the moment of inertia of a thin uniform rod of mass M and length L about an Axis perpendicular to the rod through its Centre is I₀.

The parallel axis theorem for moment of inertia states that the moment of inertia of a body about an axis passing through the centre of mass is equal to the sum of the moment of inertia of the body about an axis passing through the centre of mass and the product of mass and the square of the distance between the two axes.

The moment of inertia of the body about an axis passing through the centre of mass is given to be I₀

The distance between the two axes is L/2 (total length of the rod divided by 2

From the parallel axis theorem we have

I = I₀ + M(L/2)²

Anika asks Eva to roll a basketball and then a bowling

Alex73 [517]

Answer:

the bowling ball, because it has more mass and therefore more inertia

Explanation:

As per law of inertia we know that if an object is having more inertia then it is difficult to change state of motion.

Inertia is the property of mass of an object which always resist to change the state of motion of the object.

If an object has more inertia then it is more difficult to change the state of motion.

Now we know that we have one bowling ball and one basket ball, since bowling ball is having more mass then it must have more inertia so it is difficult to start the motion in bowling ball.

So correct answer will be

the bowling ball, because it has more mass and therefore more inertia
