Answer:I do not know because there are no number in that equation sorry
:( :(
Step-by-step explanation:
Answer:
a) 24
b) average kinetic E = 4
Step-by-step explanation:
Step 1:
we have 2 molecules = 5 kinetic E
2 moleules = 4 kinetic E
2 molecules = 3 kintec E
adding all of these up gives us the value of 24
Step 2:
average = the kintetic E of 3 values / how many different values there are which is 3
(3+4+5) / 3 = 4
Thus, the average kinetic E is 4
Answer:
∠H = 120
Step-by-step explanation:
See the attached figure
HALT is a parallelogram
So, angles H and T are supplementary.
∠H = 2x + 60 and ∠T = x + 30
∠H + ∠T = 180
∴ 2x + 60 + x + 30 = 180
∴ 3x + 90 = 180
∴ 3x = 180 - 90 = 90
∴ x = 90/3 = 30
So, ∠H = 2x + 60 = 2 * 30 + 60 = 60 + 60 = 120
i dont know this one i am soooorrrrryyy hope u get help quick
