Answer:
Explanation:
Resonant frequency is 240
4π² x 240² = 1 / LC
230400π² = 1 / LC
Let the required frequency = n
inductive reactance = 2 πn L
capacitative reactance = 1 / 2 π n C
inductive reactance / capacitative reactance
= 4π² x n ² x LC = 5.68
4π² x n ² = 1 / LC x 5.68
= 230400π² x 5.68
4n ²= 230400 x 5.68
n ²= 57600 x 5.68
n ² = 327168
n = 572 approx
Go into UEFI/BIOS setup and find the temperature monitors for the system.
Explanation:
S=(V^2-U^2)/2a a=g (gravity) a=10
=(0^2-25^2/2*(-10)
=625/20
=31.25m
Answer:
Explanation:
In order to use a device rated for use in 240 volt for use in 120 V , we have to use a step down transformer . In step down transformer no of turn in secondary coil is less than that in primary coil .
For transformer the relation is as follows
V₂ / V₁ = N₂ / N₁ = turn ratio
Where V₂ and V₁ are volts in secondary and primary coil and N₂ and N₁ is no of turns in secondary and primary coil.
Here V₂ = 120V , V₁ = 240 V
turn ratio = N₂ / N₁ = V₂ / V₁ = 120 / 240 = .5
turn ratio = .5 .
Because it is not a good conductor of heat. so the answer is D.
