Answer:
It would have an inductance closest to 16 L.
Explanation:
Inductance for a one solenoid can be calculated with a formula following:
L=μ*N^2*A/l
Then, in this situation we are increasing the number of turns by 4 without any length change. First solenoid with 50 turn has inductance L which is:
L= μ*50^2*A/l=2500*μ*A/l
When we increase the number of turns by four, it will increase to:
L'=μ*200^2*A/l=40000*μ*A/l=16 L
The answer is C why because I know it is

Answer: Option (a) is the correct answer.
Explanation:
Ionic compounds are the compounds whose atoms are combined together by transfer of electrons.
An ionic compound has partial positive charge on the cation and partial negative charge on anion.
For example, NaCl is an ionic compound whose atoms are arranged orderly due to the opposite charges on its atoms.
So, an ionic compound forms a neutral compound but not a neutral element.
Thus, we can conclude that ionic compounds form crystal structures.
Answer:
The minimum possible coefficient of static friction between the tires and the ground is 0.64.
Explanation:
if the μ is the coefficient of static friction and R is radius of the curve and v is the speed of the car then, one thing we know is that along the curve, the frictional force, f will be equal to the centripedal force, Fc and this relation is :
Fc = f
m×(v^2)/(R) = μ×m×g
(v^2)/(R) = g×μ
μ = (v^2)/(R×g)
= ((25)^2)/((100)×(9.8))
= 0.64
Therefore, the minimum possible coefficient of static friction between the tires and the ground is 0.64.
