Asample of ni3 is contained in a piston and cylinder. the samples rapidly decomposes to form nitrogen gas and iodine gas, and releases 3.30 kj of heat and does 950 j of work. what is δe? a sample of ni3 is contained in a piston and cylinder. the samples rapidly decomposes to form nitrogen gas and iodine gas, and releases 3.30 kj of heat and does 950 j of work. what is e? +953.3 j -953.3 j -946.7 j -4250 j +4250 j

answer:

idk

explanation:

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
