Answer:
Explanation:
V = J/C
V = 20/1
= 20 v
Option A is the correct answer
False
Because you can see using a thermal camera I guess
Answer:
hypothesis: Billy and Bob want to know if the amount of baking soda added to vinegar will affect the height a rocket will launch. They will measure the height of the rocket launch in meters
Explanation:
In order to make any headway with this one, it might help
to know how many joules there are in one BTU, ya reckon ?
I went and looked it up on line, you're welcome.
1 BTU = 1055.06 joules .
So if you happen to have 1,152 BTU of energy,
there are 1055.06 joules in each one of them,
and the total is
(1,152 BTU) x (1,055.06 joule/BTU)
= 1,215,429.12 joules .
Scanning the choices for anything close, we notice that choice-'b'
is only about 0.006% less than my answer. So that must be the one
they're fishing for, and they must have used 1055-even for their
conversion factor.
Answer:
τsolid = 0.15 N•m
τhoop = 0.30 N•m
Explanation:
θ = ½αt²
α = 2θ/t² = 2(14)/8.3² = 0.406445 rad/s²
Solid disk I = ½mr² = ½(4.2)0.42² = 0.37044 kg•m²
τ = Iα = 0.37044(0.406445) = 0.150563... N•m
Hoop disk I = mr² = (4.2)0.42² = 0.74088 kg•m²
τ = Iα = 0.74088(0.406445) = 0.301127... N•m
