Answer:The telegraph was invented by Samuel Morse in 1844, and telegraph wires soon sprang up all along the East Coast. During the war, 15,000 miles of telegraph cable was laid purely for military purposes. Mobile telegraph wagons reported and received communications from just behind the frontline. President Lincoln would regularly visit the Telegraph Office to get the latest news. The telegraph also enabled news sources to report on the war in a timely fashion, leading to an entirely new headache for the government: how to handle the media.
The core of Islamic law is expressed in five basic precepts, which are known as the Five Pillars of Islam that every good Muslim must honor. These are:
1. Declaration of faith. The believer must recite the following statement in order to become a Muslim, and also during the most significant events in life: <em>There is only one God and Muhammad is his messenger</em>.
2. Prayer. Muslims pray five times a day at specific hours and facing in the direction of Mecca. Praying can be performed anywhere, but, on Fridays, the afternoon prayer must be said at the mosque.
3. Alms-giving. Muslims can give spontaneously in order to please God, but, those who can also afford it, must give ten percent of their income (<em>zakat</em>).
4. Ritual fasting during the month of Ramadan. During this month (in which the Quran was revealed) Muslims must refrain from eating, drinking and having sexual relationships from dawn to dusk.
5. Pilgrimage to Mecca. Every adult Muslim that can afford it is obliged to make this pilgrimage at least once in his or her lifetime.
Answer:
A. Element Name: Flourine
no. of electrons (e^-)=Atomic number (Z)=no. of protons (p^+)
no. of neutrons (n^0)=Atomic mass-no. of protons (p^+) i.e. (n^0)=10
B. Element Name: Neon
Atomic mass=no. of electrons/protons + no. of neutrons i.e. 10+10=20
no. of protons (p^+)=no. of electrons (e^-)=Atomic number (Z)=10
Charge= -2
Explanation:
Charge is the tendency of an atom to lose or gain an electron. The gaining of electron is a positive charge (+) and the losing of an electron is a negative charge (-).
The best answer will be poison gas, machine gun, and submarines.
