Answer:
120.0v drop across the 20.0 resistor
Explanation:
From equations of motion;
v = u + at, where v = final velocity, u = initial velocity, a = acceleration, t = time taken to reach the final velocity.
Using the values given,
7 = 3 + 0.8*t=> 7-3 = 0.8t
4 = 0.8t
t = 4/0.8 = 5 seconds
They both have exactly the same acceleration.
Answer:
The standard deviation of corrected pH is
5.64 , 1.32
Explanation:
To find the measurements pH given
μx = 4.60 , σx = 1.10
So using the measurement as a pH
μₐX + b = aμ X + b
μ1.2 x + 0.12
1.2 (4.60) + 0.12 = 5.64
σₐX +b = a σ X
σ 1.2 X + 0.12
1.2 (1.10) = 1.32
The reaction of radiodecay of carbon C-14 is
C-14 --> N-14 + e- + (ve)
where e- is an electron and (ve) is an electron-type antineutrino.
Basically, when the carbon nucleus (atomic number: 6, mass number: 14) decays, a neutron of the nucleus converts into a proton (therefore, the mass number remains the same, 14, but the atomic number increases by 1, therefore it becomes nitrogen) and releases an electron-antineutrino pair.
So, the correct answer is C), N-14.
