The answer is in scientific notation 34^67 42’063 1220.
The correct form for scientific notation is a x 10^b. where a is a number or decimal such that the absolute value of a is greater than or equal to 1 and less than 10, or 1 ≤ |a|. < 10. b is the power of 10 required to make the scientific notation mathematically equivalent to the original number.
To write this number in scientific notation, you must first shift the number of decimal places from the original number by 4 places between 4 and 2. We're subtracting from the exponent because we're shifting the decimal four places to the right.

"NUCLEAR POWER" produces "no air pollution".
Option: D
<u>Explanation</u>:
As nuclear power does not emit any hazardous gas or smoke thus it produces no air pollution. But disposing of the waste is still a big issue in the case of nuclear power for which usually underground disposal in appropriate container method is opted but it's too have many disadvantages. Threat of an accident and the expenses of constructing nuclear reactors are really high so other three options are disadvantages of nuclear power.
I'd say conduction maybe I'm honestly not sure bc it has nothing to do with radiation so its between conduction and convection cause id guess they wouldn't want the heat to escape so it wouldn't be convection ???
Le déplacement est défini comme la distance entre la position initiale et finale du corps. Après un tour complet, la terre revient à sa position initiale. La distance entre la position initiale et la position finale est donc nulle.
Le déplacement de la terre est donc nul. Par conséquent, la déclaration donnée est vraie.
