Explanation:
Convergent boundaries (where plates collide) and divergent boundaries (where plates split apart).
Explanation:
v=?, u=0, a=?, S=22m.
Using the formula, S=ut+½at²
22={0×5}+(½.a.5²)
22=½.a.5²
a=44/25 = 1.76m/s².
Therefore, net force = work done = ma = 48×1.76 = 84.48N.
therefore, power = work done/time = 84.48/5 = 16.896W.
hope this helps you.
Answer:
Intermolecular forces
Explanation:
The force of attractions that act between molecules are called intermolecular forces.
Their nature is electromagnetic, this means that they are just an expression of the electromagnetic force.
One example of intermolecular force is the ionic bond: this type of bond occurs when there are two ions, one positively charged and the other one negatively charged, and they are attracted by each other due to the electrostatic force, which therefore creates a bond between them.
Other types of intermolecular forces include:
Hydrogen bond
Ion-dipole forces
Van der Waals forces
The strength of these intermolecular forces determine the state of the substance. In fact, in solids, these forces are very strong, so that the molecules are strongly bond to each other and they cannot move freely, but only vibrate about their fixed position. On the other hand, in gases, these forces are very weak, therefore the molecules are able to move freely away from each other.
Carbon-14 atom have 6 protons plus 8 neutrons.
Explanation
Carbon-12 and Carbon-14 are examples of isotopes of carbon that have huge applications in the field of science.
Isotopes are those elements who have equal number of protons and electrons whereas their neutrons differ.
Therefore isotopes have same atomic number, as atomic number depends on number of protons or number of electrons whereas number of neutrons do not have a role in atomic number.
But mass numbers of isotopes are different as mass numbers depend on the number of protons and number of electrons.
