Answer:
B hopefully this helps you with work
Work done = force × distance travelled in the direction of the force
Force= 2(9.81) = 19.62N
WD= 19.62×130= 2550.6Nm
Answer:
2000 ohms
Explanation:
Resisters in series just add.
Rt = R1 + R2 + R3
R1 = 650 ohm
R2 = 350 ohm
R3 = 1000 ohm
Rt = 650 + 350 + 1000
Rt = 2000 ohms.
The mass fraction of the hydrogen atom is 0.9995 u.
<h3>Calculation:</h3>
We know that mass fraction can be determines as,
Mass fraction = Mass of proton/mass of H atom
Given,
Mass of proton = 1.007276 u
Mass of H atom = 1.007825 u
Put the values in the formula,
Mass fraction = Mass of proton/mass of H atom
Mass fraction = 1.007276/1.007825
= 0.9995 u
Hence, the mass fraction of the hydrogen atom is 0.9995 u.
