Answer:
The net magnetic field ta the center of square is.
Explanation:
Current, I = 12 A , side ,a = 10 cm = 0.1 m
Let the magnetic field due to the one side is B.
The magnetic field is given by
Net magnetic field at the center of the square is
B' = 4 B
Answer:
Probability of tunneling is
Solution:
As per the question:
Velocity of the tennis ball, v = 120 mph = 54 m/s
Mass of the tennis ball, m = 100 g = 0.1 kg
Thickness of the tennis ball, t = 2.0 mm =
Max velocity of the tennis ball, = 89 m/s
Now,
The maximum kinetic energy of the tennis ball is given by:
Kinetic energy of the tennis ball, KE' =
Now, the distance the ball can penetrate to is given by:
Thus
Now,
We can calculate the tunneling probability as:
Taking log on both the sides:
Answer:
acidic
Explanation:
because the lower you go on the scale the more acidic it is and the closer to the middle the more neutral it is
