Answer:
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
He was brought to be believe that the earth was geocentric, meaning the earth was centered and everything orbited around it but he then published his work saying that is was heliocentric. So in the end believed in heliocentric. Let me know if this helped.
- Symbol of the ion: Br⁻.
- Name of the ion: Bromide ion.
<h3>Explanation</h3>
Br is the symbol for the element bromine. It is found in new IUPAC group 17 of a modern periodic table. Bromine is a halogen.
To name a halogen anion with charge -1, replace the suffix "-ine" in the name of the element with the suffix "-ide." For example,
The symbol of a bromine atom is Br. The atom is neutral. However, it carries a negative charge of -1 after it gains one electrons and forms a negative ion. The charge of the bromide ion shall be written as a superscript in its symbol. The size of the charge is written in front of the sign.
The charge on the bromide ion is -1. In the superscript, omit the number 1 and write "-". Hence the symbol

Ohms law E=IxR.
E=emf/voltage
I = current
R= resistance
I=E/R
I=120/10
I= 12 amps
