Answer:
either a Nitrogen atom, Oxygen atom, or a Flourine atom
Explanation:
The atom has to be more electronegative than hydrogen for the bond to form.
The refractive index of a medium is independent of (not related to) the angles of incidence or refraction. It's just a property of the medium. <em>(D)</em>
Answer:
the correct one is C
Explanation:
For this exercise we must use the work definition
W = F. s
Where the bold characters indicate vectors and the point is the scalar producer
W = F s cos θ
Where θ is the angles between force and displacement.
Let us support this in our case. The cable creates an upward tension and with the elevator going down the angle between them is 180º so the work of the cable on the elevator is negative.
The evade has a downward force, its weight so the force goes down and the displacement goes down, as both are in the same direction the work is positive
When examining the statements the correct one is C
Answer:
The resistance is .
Explanation:
Given that,
Power = 259 kV
Current = 429 A
Resistance
We need to calculate the current in each insulator
Using formula of current
Put the value into the formula
So all 95 insulators are in parallel
We need to calculate the resistance
Using formula of resistance
Put the value into the formula
Hence, The resistance is .
