Answer:
Dipole ion forces
Explanation:
Dipole ion forces are attractive forces between an ion (an atom that has lost or gained an electron, so it has a charge) and a polar molecule. A molecule is a dipole when there is an asymmetric distribution of electrons because the molecule is made up of atoms of different electronegativity. The ion then attaches to the part of the molecule that has its opposite charge: the positive end of the polar molecule faces the anion (negatively charged ion) and the negative end of the polar molecule faces the cation ( positively charged ion).
Answer:
Kinetic Enerrgy = 12744000 J or 12.744 MJ
Explanation:
Given Data:
Mass of fragment = m =1770 kg ;
Estimated speed = v = 120 m/sec ;
Solution:
As we know that
Kinetic energy = K.E = (1/2)mv²
By putting the values, we get
K.E = 0.5*1770*120²
K.E = 12744000 J
or
K.E = 12.744 MJ
So, the kinetic energy of lead-lined vault when it landed was 12.744MJ approximately.
Answer:
When the dose is high enough, ionizing radiation causes two types of harm to humans: direct tissue damage and cancer. Direct tissue damage happens when enough molecules are broken apart that the cells simply can no longer function. This can lead to radiation burns, radiation sickness, organ failure, and even death.
Because when an object is in motion it has kinetic energy
Hello!
momentum is p=mv so if the velocity is decreased by a factor of 2, which is 1/2 the value, then the momentum of that object will decrease by the same factorial.
Hope this helps, any questions please ask. Thank you!
