Answer:
The torque on the board = 11.8 Nm in the anti-clockwise direction
Explanation:
Please find attached the explanation to the answer given.
Given that,
Distance in south-west direction = 250 km
Projected angle to east = 60°
East component = ?
since,
cos ∅ = base/hypotenuse
base= hyp * cos ∅
East component = 250 * cos 60°
East component = 125 km
Answer: the correct answer is 7.8026035971 x 10^(-13) joule
Explanation:
Use Energy Conservation. By ``alpha decay converts'', we mean that the parent particle turns into an alpha particle and daughter particles. Adding the mass of the alpha and daughter radon, we get
m = 4.00260 u + 222.01757 u = 226.02017 u .
The parent had a mass of 226.02540 u, so clearly some mass has gone somewhere. The amount of the missing mass is
Delta m = 226.02540 u - 226.02017 u = 0.00523 u ,
which is equivalent to an energy change of
Delta E = (0.00523 u)*(931.5MeV/1u)
Delta E = 4.87 MeV
Converting 4.87 MeV to Joules
1 joule [J] = 6241506363094 mega-electrón voltio [MeV]
4 mega-electrón voltio = 6.40870932 x 10^(-13) joule
4.87 mega-electrón voltio = 7.8026035971 x 10^(-13) joule
mass lol ion kno man can i have the answer choices
The potential difference between the ends of the wire is 37.5 V
Explanation:
We can answer this question by using Ohm's law, which states the relationship between current, resistance and potential difference in a wire:
where
V is the potential difference
R is the resistance
I is the current
For the wire in this problem, we have:
I = 3 A is the current
is the resistance
Solving the equation for V, we find the potential difference:
