Answer:

3. lost electrons.

Explanation:

An atom that has lost an electron is positively charged because the number of protons is now greater than the number of electrons in the atom.

  • Protons are positively charged particles in an atom.
  • Electrons are negatively charged particles.
  • Neutrons do not carry any charges.

If the number of protons and electrons are the same, the atom has no charge

If the protons > electrons, the atom becomes positively charged

If electrons > protons, the atom becomes negatively charged.

Atoms becomes charged by losing or gaining electrons.

What is the magnitude of the force a 25 charge exerts on a 3 mc charge 35cm away?
lara31 [8.8K]
The electrostatic force between two charges is given by
F=k_e  \frac{q_1 q_2}{r^2}
where
ke is the Coulomb's constant
q1 and q2 are the two charges
r is the separation between the charges

In our problem, 
q_1 = 25 \mu C=25 \cdot 10^{-6} C
q_2 = 3 mC = 3 \cdot 10^{-3} C
r=35 cm=0.35 m
Therefore the electrostatic force is
F=(8.99 \cdot 10^9 Nm^2C^{-2}) \frac{(25 \cdot 10^{-6}C)(3 \cdot 10^{-3}C)}{(0.35 m)^2}= 5510 N

Question 1 A ship's position is given as 0 degrees latitude and 27 degrees west longitude. We can conclude from this information
matrenka [14]

Answer: e. on the equator and in the Atlantic Ocean

Explanation:

Latitude and Longitude are geographical coordinates.

<u>Latitude</u> is the angular distance between the <u>equatorial line</u>, and a specific point on the Earth. It is measured in degrees and is represented according to the hemisphere in which the point is located, which can be north or south latitude.  

In this sense latitude 0\° refers to the equatorial line that divides the Earth in two hemispheres (North and South).

On the other hand, <u>Longitude</u> represents the specific <u>east–west </u>position of a point on the Earth's surface, being longitude 0\° the prime meridian or Greenwich meridian.

So, if we have latitude 0\° and longitude 27\° (positive means it is to the East) we can already know the point is in the equator, and the option that bests describes the coordinates is e.
