Since density would be D=M/V, we’d have to literally divide 20 by 4.
20 divided by 4 is 5, so the density of the mineral sample is 5 grams.
Please correct me if I am wrong!
Answer:
The y-component of the electric force on this charge is 
Explanation:
<u>Given:</u>
- Electric field in the region,
- Charge placed into the region,
where, 
are the unit vectors along the positive x and y axes respectively.
The electric field at a point is defined as the electrostatic force experienced per unit positive test charge, placed at that point, such that,
Thus, the y-component of the electric force on this charge is
Using your periodic table if you look at it 3-11 are tansition metals so the horizontal Group Number will help if the group number has to digits just remove the one so if it were to be 13, the valence would be 3, if it were 14 the valence would be ,4 if it were 15, the valence would be 5, if it were 16 the valence would be 6, if it were 17 the valence would be 7 if it were group 18 the valence would be 8 so if anymore help needed to explain hit me up
Answer:
20 volts per amp (ohms), sorry the doesn't let me to type below than 20 characters
That's a description of what makes the "Wankel engine" unique.
When it first came to the USA market, it came as the guts of a
new brand of car . . . the Mazda. I don't know if some, or all, or
none of today's Mazdas still use the Wankel 'rotary' engine.
