Answer: You're converting electrical energy from the wall outlet into chemical energy inside the battery, plus a bit of wasted heat energy, since battery charging is less than 100% efficient.
Explanation:
Answer;
= g/cm^3
Explanation;
-Density is the mass per volume of a substance, or the weight per volume of an object. The Metric System is a type of system of measuring that uses only one root word for each basic dimension, such as, -gram for mass or -meter for distance.
-Metric system densities are usually in the units of mass per volume, such as g/cm^3 (gram per cubic centimeter). Where grams represents the units of mass and cm^3 represents the volume.
Rocks and minerals are usually composed of two or more minerals
The block’s average speed : 0.36 m/s
<h3>Further explanation</h3>
Distance is the length traveled by an object within a certain of time .
Average speed = total distance/total amount of time ,
Can be formulated :
ΔD= total distance
Δt= total time
A block is pulled 0.90 m to the right in 2.5 s :
ΔD= total distance = 0.9 m
Δt= total time = 2.5 s
The block’s average speed :
