Answer: The answer is 258
Explanation: The distance between the nuclei of the atoms in a diatomic molecule X2 is measured to be 516pm
Therefore the atomic radius of X2 is
516/2=258
Answer:
just put the molecules and atoms where they belong
Explanation:
Explanation:
It is given that,
Mass of the block, m = 8.15 kg
Time, t = 0.521 s
It is pulled through a distance of 3.62 m, s = 3.62 m
Initially, u = 0
Spring constant of the spring, k = 415 N/m
We need to find the stretching in the spring. Firstly, we will find the acceleration of the block. It can be calculated using second equation of motion as :
![s=ut+\dfrac{1}{2}at^2](https://tex.z-dn.net/?f=s%3Dut%2B%5Cdfrac%7B1%7D%7B2%7Dat%5E2)
![a=\dfrac{2s}{t^2}](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7B2s%7D%7Bt%5E2%7D)
![a=\dfrac{2\times 3.62\ m}{(0.521)^2}](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7B2%5Ctimes%203.62%5C%20m%7D%7B%280.521%29%5E2%7D)
![a=26.67\ m/s^2](https://tex.z-dn.net/?f=a%3D26.67%5C%20m%2Fs%5E2)
Now, the force due to this acceleration is balanced by the force in spring as :
![ma=kx](https://tex.z-dn.net/?f=ma%3Dkx)
![x=\dfrac{ma}{k}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7Bma%7D%7Bk%7D)
![x=\dfrac{8.15\ kg\times 26.67\ m/s^2}{415\ N/m}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B8.15%5C%20kg%5Ctimes%2026.67%5C%20m%2Fs%5E2%7D%7B415%5C%20N%2Fm%7D)
x = 0.52 meters
So, the spring is stretched by 0.52 meters. Hence, this is the required solution.
Answer:B
Explanation:
For work to be done, the object must move some distance as a result of a force
Answer:
Light rays that come from a source such as the sun reflect off items and enter our eye. ... While black objects absorb the energy from all colors and become hot, the objects gradually release some of that energy back into the air around it
