A transverse wave is a wave where the particles in the medium move perpendicular (at right angles) to the direction of the source or its propagation (think of a snake slithering through grass) an example of a transverse wave could be a light wave. Light waves for instance don’t need a medium in order to propagate but transverse waves in general do need a medium.
Answer:
Each carbon atom is covalently bonded to four other carbon atoms in diamond. A lot of energy is needed to separate the atoms. This is because covalent bonds are strong. This is the reason why diamond has a high melting point.

Explanation:
The normal force exerted on the car by the walls of the cylinder at the bottom of the vertical circle will be such that when substracted to the weight it must give the centripetal force, since at that point on the vertical 
We also know that the equation for the centripetal force is:
Mixing both equations we get:
Which for our values means:
Answer:
3600 J
Explanation:
Kinetic energy of an object is the energy posses by an object solely due to its motion.
It can also be defined as the amount of work that can be done when an moving object come to test.
Kinetic energy of an object can be calculated by the equation,
K.E. = ½mv²
Where m = mass, v = velocity
So you get,
K.E. = ½×0.5×(120)² = 3600 J
