Answer:
True
Explanation:
There are two types of Van der waals forces which are intermolecular bonds. These bonds are London dispersion forces and Dipole-dipole attractions.
The london dispersion forces are weak attractions found between non-polar molecues and noble gas.
The attractions here is as a result of the fact that non-polar molecules or atoms sometimes becomes polar because the constant motion of its electrons may lead to an uneven charge distribution at an instant. This leads to the formation of a temporary dipole or instantaneous dipole. The dipole can induce the neighbouring molecules to be distorted and they form dipoles as well.
Answer:
294,3
Explanation:
While g = 9,81 m/s^2 then:
![E=2[kg]*9,81[\frac{m}{s^2} ]*15[m]=294,3 [J]](https://tex.z-dn.net/?f=E%3D2%5Bkg%5D%2A9%2C81%5B%5Cfrac%7Bm%7D%7Bs%5E2%7D%20%5D%2A15%5Bm%5D%3D294%2C3%20%5BJ%5D)
