Answer:
the answer is B. Twice a month
Explanation:
on Edge.
Answer:
<u>The answer is the third option.</u>
Explanation:
The electrostatic force, Coulomb's force, is a force that depends on the inverse of the square distance, it is a non-contact force.
On the other hand, stretched spring is a contact force, it needs a contact external force.
Therefore, <u>the answer is the third option.</u>
I hope it helps you!
A) 222 N/m
Explanation:
Hook's law gives us the relationship between force (F), displacement with respect to the original length (x) and spring's constant (k):

In this part of the problem, we have:
F = 120 N - 100 N = 20 N is the new force applied
x = 9.0 cm = 0.09 m is the displacement relative to the initial stretched position
Solving the equation for k, we find the spring constant

B) 45 cm
We can use Hook's law also for this part of the exercise:

where this time we have
F = 100 N (the original pull applied)
k = 222 N/m
Solving the equation for x, we find the original displacement:

A variation of traits could be a variation of personality traits? everybody is different? what I do know Is that variation can be inherited or environmental which means that you get it from your ancestors through DNA or you get it from the environment around you
Answer:
The fundamental frequency and the length of the pipe are 115.8 Hz and 1.48 m.
Explanation:
Given that,
First frequency = 986 Hz
Second frequency = 1102 Hz
We need to calculate the length of the pipe
Using formula of length

Put the value into the formula



We need to calculate the fundamental frequency of this pipe

Put the value into the formula


Hence, The fundamental frequency and the length of the pipe are 115.8 Hz and 1.48 m.
