It is called the fovea centralis.
Answer:
1. Plateau where the temperature stays constant
2. Melting
3. Boiling points of the substance
Explanation:
The relationship between kinetic energy and temperature is given as follows;

Where;
= The average kinetic energy of the atom
R = The universal gas constant
= Avogadro's number
T = The temperature in Kelvin
Therefore, the kinetic energy increases as the temperature increases, however when the energy is not being converted into kinetic energy, the energy is stored as internal potential energy in the melted or evaporated state of the substance
Therefore, we have;
If energy is going into a system, but not being converted into kinetic energy, it will be converted into potential energy. This will be represented by a 1. <u>plateau where the temperature stays constant</u> on a heating curve, which occur at the 2. <u>melting</u> and 3. <u>boiling points of the substance.</u>
Heat is a form of energy, and heat melts objects
Answer:
C. 13.89 meters/second
Explanation:
If the velocity of the train is v=s/t, where s is the distance and t is time, then v=400/5=80m/s. To get the vertical component of the velocity we need to multiply the velocity v with a sin(α): Vv=v*sin(α), where Vv is the vertical component of the velocity and α is the angle with the horizontal. So:
Vv=80*sin(10)=80*0.1736=13.888 m/s.
So the vertical component of the velocity of the train is Vv=13.888 m/s.
