Scientists believe that light is made of streams of particles because light exhibits the particle nature. This can be explained on the basis of photoelectric effect observed when light is made to fall on the surface of a metal. when light falls on the surface of a metal, it makes the electron to eject out. This is possible only when light consists of small particle called photons. hence the scientists believe that light is made of streams of particles.
Carbon is an important compound on the earth. This is really visible in Carbon Dioxide. The valence electrons are important because they allow many different types of bonds to occur.
Answer:
i₀ = V / R_i
Explanation:
For this exercise we use Ohm's law
V = i R
i = V / R
the equivalent resistance for
= ∑ 
if all the bulbs have the same resistance, there are N bulbs
R_{eq} = R_i / N
we substitute
i = N V / Ri
where i is the total current that passes through the parallel, the current in a branch is
i₀ = i / N
i₀ = V / R_i
Answer:
Geology is the study of the Earth that involves the process at Earth, materials of which it is made, and its history.
<u>Geologists combine both laboratory and field data to illustrate the results of their research. Some observations that can the geologist make by working outdoors instead of in a lab are as follows:</u>
- Understanding and exploring the earth's surface closely using geophysical tools.
- Collecting samples by own and make some interpretations at the same time.
- Observation of the landscapes
- Close observation of outcrops
The power P in watts (W) is equal to the energy E in joules (J), divided by the time period t in seconds (s):
P(W) = E(J) / t(s)
2.78 Watts
