Boron, Aluminum, Gallium, Indium, Thallium
Answer:
None.
Explanation:
Molecules are formed by an element's need or excess of electrons. For example, in nature oxygen generally exists as 02. Other molecules are formed via chemical reaction. The example here is the burning of gasoline. Gasoline's two main byproducts are water and carbon dioxide.
Hydrogen as an atom has one electron making it unstable. Put a second hydrogen atom next to the first and the two atoms will share electrons to fill the first energy level the atom needs to be stable.
Answer:
The value is ![KE_b =0.710 \ J](https://tex.z-dn.net/?f=KE_b%20%3D0.710%20%5C%20J)
Explanation:
From the question we are told that
The mass of the bullet is ![m_b = 5.00 \ g = 0.005 \ kg](https://tex.z-dn.net/?f=m_b%20%20%3D%205.00%20%5C%20g%20%20%3D%200.005%20%5C%20%20kg)
The mass of the wood is ![m_w = 900 \ g = 0.90\ kg](https://tex.z-dn.net/?f=m_w%20%3D%20%20900%20%5C%20%20g%20%20%3D%20%200.90%5C%20%20kg)
The height attained by the combined mass is ![h = 8.0 \ cm = 0.08 \ m](https://tex.z-dn.net/?f=h%20%3D%20%208.0%20%5C%20cm%20%20%3D%20%200.08%20%5C%20m)
Generally according to the law of energy conservation
![KE _b = PE_c](https://tex.z-dn.net/?f=KE%20_b%20%20%3D%20%20PE_c)
Here
is the kinetic energy of the bullet before collision.
and
is the potential energy of the combined mass of bullet and wood at the height h which is mathematically represented as
![PE_m = [m_b + m_w] * g * h](https://tex.z-dn.net/?f=PE_m%20%20%3D%20%20%5Bm_b%20%20%2B%20m_w%5D%20%2A%20%20g%20%2A%20%20h)
So
![KE_b =PE_c = [0.005 + 0.90] * 9.8 *0.08](https://tex.z-dn.net/?f=KE_b%20%3DPE_c%20%20%20%3D%20%5B0.005%20%20%2B%200.90%5D%20%2A%209.8%20%2A0.08)
=> ![KE_b =0.710 \ J](https://tex.z-dn.net/?f=KE_b%20%3D0.710%20%5C%20J)
Answer:
B. 4 m/s
Explanation:
v=d/t
Running for 300 m at 3 m/s takes 100 seconds and running at 300 m at 6 m/s takes 50 seconds. 100 s + 50 s = 150 s (total time). Total distance is 600 m, so 600 m/ 150 s = 4 m/s.
In simple words, flux can be stated as the rate of flow of a fluid, radiant energy, or particles across a given area.
<u>Explanation:</u>
<u>Mutual Flux:</u>
- The magnetic lines present in among two magnets or solenoid is mutual flux.
- These are the lines in which the attraction and repulsion happens.
- The SI unit of mutual flux is the Henry
<u>Leakage Flux:</u>
- In simple words, it can be stated as the magnetic flux which does not follow the specially designed way in a magnetic circuit.
- Leakage flux in the induction motor takes spot due to current runs through the essence of the induction motor.
- The SI unit of Leakage flux is the Weber
<u>Magnetizing flux</u>
- Magnetic flux is an analysis of the entire magnetic field which moves in a given field
- In simple words can be defined as the Magnetic flux is what generates the field around a magnetic material.
- The SI unit of magnetic flux is the Weber
