The answer is donate, therefore elements with positive valences usually donate electrons
Answer:
Spring constant, k = 24.1 N/m
Explanation:
Given that,
Weight of the object, W = 2.45 N
Time period of oscillation of simple harmonic motion, T = 0.64 s
To find,
Spring constant of the spring.
Solution,
In case of simple harmonic motion, the time period of oscillation is given by :
![T=2\pi\sqrt{\dfrac{m}{k}}](https://tex.z-dn.net/?f=T%3D2%5Cpi%5Csqrt%7B%5Cdfrac%7Bm%7D%7Bk%7D%7D)
m is the mass of object
![m=\dfrac{W}{g}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7BW%7D%7Bg%7D)
![m=\dfrac{2.45}{9.8}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B2.45%7D%7B9.8%7D)
m = 0.25 kg
![k=\dfrac{4\pi^2m}{T^2}](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7B4%5Cpi%5E2m%7D%7BT%5E2%7D)
![k=\dfrac{4\pi^2\times 0.25}{(0.64)^2}](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7B4%5Cpi%5E2%5Ctimes%200.25%7D%7B%280.64%29%5E2%7D)
k = 24.09 N/m
or
k = 24.11 N/m
So, the spring constant of the spring is 24.1 N/m.
I can only offer you one which is mushroom. They're fungus' and they can't produce their own food. They get their food from decaying and dead animals and absorb it through their roots.
Answer:
Isotopes are the elements having the same atomic number i.e same number of protons which in turn is equal to same number of electrons. Number of protons and electrons are equal as the atom is electrically neutral. So, the only option is A.
I hope it helps you !
Personally, I know that I don't however it all depends on the person's lifestyle, health, and resoucres, such as if they are able to complete the excersise or have enough money fore equpemnt. To be safe, I would say that the majority of people do follow the guidelines although they may manipulate it to fit their best interest.
