The distance the truck traveled is 190
Explanation:
I added 30, 45, 50, 65 together to get the total distance
Answer: option <span>D. be given a positive charge produced by the movement of electrons to the other end of the ball.
</span>
Explanation:
This phenomenon is called electrostatic induction.
The excess of negative charge on the end of the rod will repel the electrons on the side of the pith ball that have been approached to it.
Then the electrons on the pith ball will move far away from this end with it will be left an excess of positive charge.
In this way the rod has induced that the ball acquires a positive charge on one end and a negative charge on the other end.

Answer:
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other.
Copper: (per atom)
Number of protons = 29
Number of electrons = 29
Number of neutrons = 35
Nickel: (per atom)
Number of protons = 28
Number of electrons = 28
Number of neutrons = 31
Iron: (per atom)
Number of protons = 26
Number of electrons = 26
Number of neutrons = 30
Manganese: (per atom)
Number of protons = 25
Number of electrons = 25
Number of neutrons = 30
Types of rocks: Igneous, sedimentary, and metamorphic
There are over 200 names of minerals, I'm not sure what you want for that
