Potassium goes to argon so that a proton in the K nucleus "vanishes" into a positron (positive electron ?) but keeps the same atomic mass at 38. ? I'd say that the number of the positron was 0, and the charge was +1 electronic charge.
Answer:
Explanation:
Using Hooke's law,
F = -kx
Where,
F = force of the mass
k = spring constant/stiffness
x = length of the spring
Given:
F1 = m1*a
= 4.1 * 9.81
= 40.221 N
F2 = m2*a
= 1.5 * 9.81
= 14.715 N
x1 = 2.9 cm
F1/x1 = F2/x2
Therefore,
x2 = (14.715 * 2.9)/40.221
= 1.06 cm.
