I would assume you answer them by doing the math required.
False , the gas petal makes the speed go up
Explanation:
Electronegativity is the property of an atom that attracts the shared pair of an electron to itself. There is a trend in the periodic table.
While moving down in a group, the electronegativity decreases. This is due to the reason that as we move down the number of shells added and so the electron become very far from the pull of the nucleus.
As we move across a period the electronegativity increases. This is because of the no. of charge on the nucleus increase.
Answer: Cannot determine cause we need to know the change of time to calculate the work.
Explanation:
m = 0.5kg
V = 3m/s - 5m/s = -2m/s
P = W/t = Fv
F = ma
W = Fvt
W = (0.5)(9.8)t = 4.9t
Scientific law are proven scientific fact a theory isn’t it could be if you provide details of how it is a fact with investigations and observations,data and etc
