Deuterium is also known as heavy hydrogen and takes the symbol 2H. What makes this heavy is due to the additional neutron present in it. Therefore, everything that is being mentioned above as the description of deuterium is applicable. Therefore, the answer would be option E: All of the above. Hope this helps.
On the half way down (object falling down with the initial speed = 0)
Answer :
The time is 0.46 sec.
Explanation:
Given that,

Voltage = 1.5 V
Length = 5.5 cm
Resistivity of gold
We know that,
The resistance is
...(I)
The current is
...(II)
Put the value of R
We need to calculate the drift velocity
Using formula of drift velocity
Put the value into the formula
We need to calculate the time
Using formula of time
Put the value into the formula
Hence, The time is 0.46 sec.
Answer:
0.0217 m
Explanation:
Ftom the question,
Applying Coulomb's law
F = kqq'/r²............... Equation 1
Where F = Electric Force, q and q' = First and second charge respectively, r = distance between the charges, k = coulomb's constant.
make r the subeject of the equation
r = √[(kqq')/F]............. Equation 2
Given: q = +3.6×10⁻⁸ C, q' = -3.2×10⁻⁸ C, F = -2.2×10⁻² N
Constant: k = 8.98×10⁹ Nm²/C²
Substitute these values into equation
r = √(+3.6×10⁻⁸×-3.2×10⁻⁸×8.98×10⁹/-2.2×10⁻²)
r = √(-103.4489×10⁻⁷/-2.2×10⁻²)
r = √(47.02×10⁻⁵)
r = 21.68×10⁻³
r ≈ 21.7×10⁻³ m.
r ≈ 0.0217 m
Hence the seperation between the two balloons is 0.0217 m
