Carbon-13 has an atomic mass of 13.
Atomic mass is the sum of protons and neutrons.
There are 6 protons, so there are 13 - 6 = 7 neutrons.
Answer is 7 neutrons (and 6 electrons)
Weight: it is the gravitational pull applied on a body by the earth’s surface
Mass: it is the amount of matter present
Convergent boundaries move towards each other. They can be classified as continental-continental, or oceanic-continental.
Oceanic-Continental: Heavier oceanic plate slides under a continental plate in a process called subduction.
Continental-Continental: Tectonic plates push up against each other and often fold upwards, creating mountain ranges.
Answer:
Option B
Explanation:
I did a question like this a long time ago so i'm not sure if its right so sorry if its wrong
Answer:
the potential energy is 114 J.
Explanation:
Given;
total mechanical energy, E = 400 J
kinetic energy, K.E = 286 J
The potential energy is calculated as follows;
E = K.E + P.E
where;
P.E is the potential energy
P.E = E - K.E
P.E = 400 J - 286 J
P.E = 114 J
Therefore, the potential energy is 114 J.
