Explanation:

1) region outside the nucleus divided into energy levels : electron cloud

Energy levels are specific spherical orbitals around the nucleus. The region of maximum probability of where an electron is located is called an electron cloud or orbital.

2) located in the outermost energy level, determines how element will react chemically with other elements: valence electrons

Valence electrons are electrons in the outermost energy shell of an atom. They determine whether an atom will react chemically with other elements of not.

3) outermost energy level : valence shell

The valence shell where the outermost electrons are located is the outermost energy level.

4) atoms that have the same number of protons but different numbers of neutrons : isotopes

Isotopes are atoms having the same number of protons but different number of neutrons. They generally have the same chemical properties. They have the same atomic number but different mass number.

5) located in the nucleus, neutral or no charge : neutrons

Neutrons are subatomic particles in the nucleus with no charges on them.

6) located outside the nucleus, negative(-) charge : electrons

Electrons are subatomic particles that carries negative charges

7) located in the nucleus, positive(+) charger: protons

Protons are positive charges in the nucleus of an atom.

A speeder passes a parked police car at a constant speed of 23.3 m/s. At that instant, the police car starts from rest with a un

KonstantinChe [14]

Answer:

32s

Explanation:

We must establish that by the time the police car catches up to the speeder, both have travelled a certain distance during the same amount of time. However, the police car experiences accelerated motion whereas the speeder travels at a constant velocity. Therefore we will establish two formulas for distance starting with the speeder's distance:

$x=vt=23.3\frac{m}{s}t$

and the police car distance:

$x=vt+\frac{at^{2}}{2}=0+\frac{2.75\frac{m}{s^{2}} t^{2}}{2}=0.73\frac{m}{s^{2}}$

Since they both travel the same distance x, we can equal both formulas and solve for t:

$0 = 0.73\frac{m}{s^{2}}t^{2}-23.3\frac{m}{s} t\\\\0=t(0.73\frac{m}{s^{2}}t-23.3\frac{m}{s} )\\\\$

Two solutions exist to the equation; the first one being $t=0$

The second solution will be:

$0.73\frac{m}{s^{2}}t=23.3\frac{m}{s}\\\\t=\frac{23.3\frac{m}{s}}{0.73\frac{m}{s^{2}}}=32s$

This result allows us to confirm that the police car will take 32s to catch up to the speeder

When a solid is placed in a container and heat is applied, a phase change occurs. Watch the video and identify which of the foll

goldenfox [79]

Answer:

a) false b) true c) true d) false and e) true

Explanation:

a) false. All the energy applied is used for the phase change, so the temperature remains constant.

b) true. The kinetic energy is associated with the speed of the particles and they have more mobility in the liquid, therefore, more kinetic energy.

c) true. Since energy is used for state change

d) false. In general, mobility and temperature are proportional

e) true. Heat is the source of energy for the change of state

Which is the best example of the transfer of heat through radiation

boyakko [2]

Nitially the flame produces radiation which heats the tin can. The tin can thentransfers heat to the water through conduction. The hot water then rises to the top, in the convection process.
