Which best describes the runners?
Garreth and Elisa ran the same distance but not the same displacement, Luigi and Jasmine went the same displacement,
and Logan ran faster than Jasmine.
Garreth ran farther than Luigi, Elisa and Jasmine went the same distance, and Logan and Jasmine has the same
displacement in the opposite direction.
Garreth and Elisa ran together, Luigi and Jasmine went the same distance, and Logan and Jasmine have the same
displacement in the opposite direction.
Garreth ran less than Logan, Elisa and Jasmine went ame displacement, and Luigi and Garreth ran together.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
