Answer:

22m/s

Explanation:

Given parameters:

Time  = 5s

Acceleration  = 4m/s²

Initial velocity  = 2m/s

Unknown

Final speed  = ?

Solution:

To solve this problem, we use the expression below;

         v = u + at

v is the final speed

u is the initial speed

a is the acceleration

t is the time taken

 So, insert the parameters and solve;

         v  = 2 + 4 x 5  = 22m/s

Which type of seismic waves produces the most severe ground movement?
Leto [7]
The surface waves are the type of seismic waves that produce the most severe ground movement. This wave is slow in nature and so produces a rolling effect similar to a surface wave in a pond. This kind of wave is far more devastating than the P waves and the S waves. The surface waves have the capacity to shake a building from side to side until it collapses. This kind of wave moves in a pattern similar to a circle. It actually originates at a point and then start moving outwards in a circle.

Explain specifically how an electron gives off light in an atom.
exis [7]

Answer:

Then, at some point, these higher energy electrons give up their "extra" energy in the form of a photon of light, and fall back down to their original energy level.

Explanation:

When properly stimulated, electrons in these materials move from a lower level of energy up to a higher level of energy and occupy a different orbital.

How does radioactive isotopes decay?
aksik [14]
They can decay through one of three ways: 
alpha decay
beta decay and
gamma decay
ALPHA- particle with two neutrons and two protons is ejected from the nucleus of the radioactive atom. this particle released is called an alpha particle. Only occurs with heavy metals.
BETA- pretty much when a proton is transformed into a neutron, or vise versa. in a beta minus decay, the nuetron decays into a proton and in a beta plus decay, a proton decays into a neutron
GAMMA- the nucleus changes from a high energy state to a low energy state by releasing electromagnetic radiation (photons). the number of protons and neutrons stay the same during this reaction therefore the element is still the same.
