For the given question above, there are other details that is missing. Here is what I got from my research.
Mass of a hydrogen atom as 1.008 u,
<span>where 1 u=1.661 times 10^-27 kg.
</span>The frequency of a mass on a spring is:
<span>f = omega / 2pi = sqrt (k/meff) / 2pi </span>
<span>The meff you use is the effective mass. If two bodies with mass M and m are both free to move: </span>
<span>Meff = Mm / (M+m) </span>
<span>If M=m, then Meff = m/2 (as you were given) </span>
<span>So the answer is: </span>
<span>f = sqrt (2k/m) / 2pi </span>
Answer:
Explanation:
At the bottom of the pipe :
= Normal force acting in upward direction
= mass of the ball
= weight of the ball acting in downward direction = mg
= speed of the ball at the bottom
= radius of curvature
Force equation for the motion of ball is given as
Answer:
9.0 m
Explanation:
Applying
V = kq/r......................... Equation 1
Where V = Electric potential, q = charge, r = distance, k = Coulomb's constant.
make r the subject of the equation
r = kq/V................... Equation 2
From the question,
Given: q = 1.00×10⁻⁵ C, V = 10000 V
Constant: k = 9.0×10⁹ N⋅m²/C²
Substitute these values into equation 2
r = (9.0×10⁹×1.00×10⁻⁵)/10000
r = 9.0 m
Answer:
Nebulae contribute more to stellar formation than other regions because:
Explanation:
A.They have an unlimited supply of hydrogen.
B. They are believed to be rich in hydrogen and helium.
C. They have a three strong gravitational pull.
This are the reasons that Nebulae contribute more to stellar formation than other regions.
