The primary source would be the original article published in a scientific journal. All other choices would be based on information from the original article.

Newspapers would only pick up the information from the journal itself, or from the authors. Books follow after the original article, after it has gained momentum among the research community. The public lecture at a museum would be based on work from the journal article.

a 2.5 kg mass is hung from the 0 cm mark on a 1 kg meter stick. a mass of 0.5 kg is hung from the 100 cm mark of the meter stick
Keith_Richards [23]

The center of mass of this system is <u>25 cm.</u>

<u />

The middle of mass of a distribution of mass in the area is the particular factor in which the weighted relative function of the distributed mass sums to zero. this is the factor to which a force may be implemented to reason a linear acceleration without an angular acceleration.

Calculation:-

X centre of mass = (0 × 2.5) + ( 1× 50) + (0.5 × 100) / 2.5 + 1 + 0.5

                             = <u>25 cm</u>

<u />

The center of mass is a role defined relative to an object or machine or gadget. it is the average position of all of the parts of the gadget, weighted according to their masses. For easy rigid objects with uniform density, the middle of mass is placed on the centroid.

kvasek [131]

Answer:

Dropping a stone from a height is work  

Explanation:

Work is the action of a force through a distance.

w = fd

The Earth's gravitational attractive force is pulling the stone to its centre, so the Earth is doing work on the stone.

Newton’s Second Law of motion defines force in terms of mass and acceleration, F= ma. Which of the following is false? The term
NikAS [45]

Answer:

The forces creating the net force must lie in the same direction.

Explanation:

newton's second law states that the net force acting on the body is equal to the product of mass and the acceleration of the body.

If there are several forces acting on the body in different directions, then we have to find teh net force by using the vector sum and then find the acceleration.

It is not necessary that all the forces acting in the same direction.

if they are in different directions then we have to find the net force by t=using the formula for the vector sum.
