Three bonds
<span>Here are the combinations of hydrogen with boron, carbon, nitrogen, oxygen and fluorine. Generally to complete an octet Group 4A will form four bonds, Group 5A will form 3 bonds, Group 6A will form 2 bonds, etc. Three bonds: Boron is in group 3A. It has three valence electrons.</span>
Answer:
B = 4.323 T
Explanation:
We are given;
Inner radius; r_i = 0.7 m
Number of turns; N = 890 turns
Current; I = 17 KA = 17000 A
Formula for the magnetic field inside the toroid along the inner radius is given by;
B = (μ_o × N × I)/(2πr)
μ_o is vacuum of permeability with a constant value of 4π × 10^(-7) H/m
Plugging in the relevant values, we have;
B = (4π × 10^(-7) × 890 × 17000)/(2 × π × 0.7)
B = (2 × 10^(-7) × 890 × 17000)/(0.7)
B = 4.323 T
I think that i am right about it all okay so dont ask why
Answer:
The first model of the atom was developed by JJ Thomson in 1904, who thought that atoms were composed purely of negatively charged electrons. This model was known as the 'plum pudding' model.

Sorry that's all I know ♂️
Answer:
c
Explanation:
It really depends on what the stuff is. This should not be a math or physics question.
Having said that, I answer it by rounding it to 1. 1.04 is closest two one.
That is not entirely a satisfactory answer. Most people who take medications have pill splitters. They easily cut a pill in half. They can do this only if a the medicine's directions, or a pharmacist, or a doctor tells you can do this. Cutting it into quarters should never be done.
So a is really incorrect medically.
1.5 is too far away
C is probably the intended answer; it would annoy me no end if it was anything but c. If this was just a rounding question, it rounds to c. There is no medication that requires an intake of 1.04. No one could get that kind of accuracy.
2 is really too far away.
