Answer:
The rod`s charge must be positive, because the gravity force is pointing downwards and the electrostatic force must be pointing upwards (in order to balance the gravity force)
The charge is q_2 = 1.667 times 10^(-7) C
Explanation:
F_e = F_g
where F_g = m g and F_e= (1/4 pi e_0)*(q_1*q_2)/d^2,
please see the file attached for more details.
Chlorine needs to gain one electron and sodium needs to lose one electron
Answer:
Part a)

Part b)

Explanation:
Part a)
As we know that there is no friction in the path
So here we can use energy conservation to find the distance moved by the mass
Initial spring energy = final gravitational potential energy
so we will have




Part b)
Now if spring is connected to the block then again we can use energy conservation
so we will have

so we will have



so total distance moved upwards is

<span> flow rate = velocity of fluid x area of cross section x density
= 42 x 2 x 1 = 84 g/s</span>
Biodiversity refers to the huge variety of all organisms present on the Earth, which conform to the natural world.
- The term biodiversity can be considered as a contraction of "biological diversity" and it was developed by Dr. Walter G. Rosen in 1985.
- Biodiversity includes all biological kingdoms, i.e., Eukaryota (animals, plants, fungi, and protists), Archaea and Bacteria.
- Biodiversity can be defined as different values which can be used to measure the genetic variation and variations at organismal (species) and ecosystem levels.
In conclusion, biodiversity refers to the huge variety of all organisms present on the Earth, which conform to the natural world.
