displacement of the plane is given as

time taken by the plane

now the velocity is given as



so the velocity of airplane is 399 mi/h towards South West
Answer:
The magnetic field is 
Explanation:
From the question we are told that
The inner radius is 
The outer radius is 
The distance from the axis of the conductor is 
The current carried by the conductor is 
According to Ampere's circuital law , the magnetic field at a point that is
from the axis of the conductor

Answer:
True
Explanation:
Because the resistors in series is the sum of the two resistors given as
R= R1+R2
While that of resistors in parallel is the sum of the reciprocal of the resistance given as
1/R = 1/ R1+ 1/R2
So that of series connection will be greater
Answer:
Quantity of heat or heat energy
Explanation:
the quantity of heat is the calculation of the total quantity of thermal energy in an object. it's S.I unit is joules (J) and the symbol for calculating it is Q.
