Given Information:
Diameter of solenoid = 5.0 cm
Magnetic field = B = 2.0 T
Rate of change of magnetic field = 3.0 T/s
Required Information:
Electric field strength inside the solenoid at a point on the axis = ?
Answer:
The electric field strength inside the solenoid at a point on the axis is zero.
Explanation:
From the Faraday's Law
E = -r/2 dB/dt
Where dB/dt is the rate of change of magnetic field and r is zero because the distance from the axis is zero.
Therefore, electric field strength inside the solenoid at a point on the axis is 0.
Parallax of the stars is created by :
B. Different locations of Earth in its orbit
Parallax refer to the position of an object (in this case, a star) that will look different if we view it from different positions

82 ÷ 6.5 = 12.615384615384... repeating
round = 12.6
12.6 · 6.5 = 81.9
round = 82
She went an average of 12.6 km an hour
Hope this helps! ;)
