Meters it the SI unit for measuring length.
Answer:
potential energy increases.
Explanation:
The potential energy between the two charged particles is given by
U = k Q q / r
If they are very far apart then r tends to infinity and the potential energy is zero.
If they come closer then the potential energy between the two charged particles increases.
Thus, the potential energy increases.
Answer:
14.8 m
Explanation:
S= ut + 
a
where u = initial velocity
S= (0 
)(2
) + (7.4
)(2
)
S= (7.4)(2)
S=14.8 m
The question is asking to calculate the tension that the string has to adjust the string so that when vibrating in its second overtone, it produces sound of wavelength of 0.761m, base on my calculation, the calculation must be done by the formula of <span>v=λf</span><span>., I hope this would help </span>
