Amassive tractor rolls down a country road. in a perfectly inelastic collision, a small sports car runs into the machine from behind. (i) which vehicle experiences a change of momentum of larger magnitude? a) the car does b) the tractor does c) their momentum changes are the same size d) it could be either vehicle (ii) which vehicle experiences a larger change in kinetic energy? a) the car does b) the tractor does c) their kinetic energy changes are the same size d) it could be either vehicle

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

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 =
