Worth of zinc is contained in hair cut in the united states is $ 20,000.

Step-by-step explanation:

Cost of a kg of zinc = $ 4

To find: Worth of zinc is contained in hair cut in the united states

Weight of the hair cut in US = 25000000 kg

Weight of zinc in a kg of hair = 0.0002 kg

⇒ Weight of zinc in 25000000 kg of hair = 0.0002 × 25000000 = 5000 kg

Now, Cost of a kg of zinc = $ 4

Therefore, Worth of zinc is contained in hair cut in the united states is $ 20,000.

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
