Because other scientists and science in general rely on their collegues' research which in turn allows development of our knowledge on the given subject. The more dont-to-earth reason may be safety. If someone performs an experiment without knowledge of its true results it might result in some danger to the safety of those perforning it without knowledge of all the risks.
Electrons that are further away from the nucleus have more energy. As they enter an "excited" state, they jump up orbits.
Answer- Helium
You can by the number of protons, and if you look at a periodic table the atomic number of helium is the same as the number of protons
The electric furnace will consume 9600 watt of power.
To find the answer, we need to know about the electric power.
<h3>What's the electric power?</h3>
- Electric power is defined as the product of voltage and current.
- Mathematically, power= V×I
- Its si unit is watt.
<h3>What will be the power consumed by an electric furnace that draws 40A with an applied voltage of 240V?</h3>
The power = 240×40 = 9600 watt
Thus, we can conclude that the power consumption of the electric furnace is 9600 watt.
