Which could complete the liquid phase description in the venn diagram?
a) definite shape and low energy particles
b) no definite shape and no definite volume
c) no definite shape and high energy particles
d) no definite shape and medium energy particles

The answer is D

Explanation:

Underneath the black box says 'definite'. So circle A has definite volume and shape, and has the lowest energy particles. This describes a solid. Circle C says no definite volume and has the highest energy particle, so it's a gas. That leaves only liquid. Liquids don't have a definite shape, since they take they shape of whatever container they're in. They also have the medium energy particles. So the answer is D.

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

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
