I believe that moscovium has 404 subatomic particles because it has 115 protons, 115 electrons, and 174 neutrons
1j=1newton*meter
force=mass*accel
200N=55x
200/55=3.636......
3.636...-2=1.636.....
1.636 is the deceleration resulting from friction hence the force of friction is 1.636*55=90newtons
90newtons*distance of 10 meters= 900 j of work done by friction
It is known as silicon dioxide or silica!
Hope this helps!
Explanation:
The unit of volume derived from SI units(1) is the cubic meter, m3.
Chemists in a laboratory usually deal with much smaller volumes than cubic meters and the metric but non-SI units of liter or litre (L) and milliliter or millilitre (mL or ml) are in common use.
In 1964 the litre was redefined as being equal to exactly 1 cubic decimetre:
1 L = 1 dm3
So 1 milliltre = 1 cubic centimetre
1 mL = 1 cm3 (= 1cc)
Other metric units of measuring volume are given in the table below:
large volume → → → → → → → → → → small volume

Answer: figure A
Explanation:
Electric field lines point away from positive charges (like charges repel) and towards negative charges (unlike charges attract). ... Field lines do not touch or cross each other. Field lines are drawn perpendicular to a charge or charged surface. The greater the magnitude of the charge, the stronger its electric field.
Figure B shows a positive charge but has a negative field line so that’s wrong.
Figure C shows a negative charge but has a positive field line so that’s wrong.
Figure D shows a negative charge but has no perpendicular field lines so that’s wrong.
