If a = 2.0 cm, b = 5.0 cm, and i = 20 a, 6.0 μt is the magnitude of the magnetic field at the point p, So the correct option is (a).
The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field. A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field.

Answer:
Explanation:
we know that 1 km =1000 m and 1 hour=3600 sec
therefore
15 km/hr=15*1000 m/3600 sec=4.167 m/s
The Big Bang theory is matter and energy in the universe exploded out from one point. As the explosion occurred, energy and matter spread outward and formed the universe. The matter from the Big Bang formed clouds of gas.
Answer:
Push and pull is the 3rd motion.
The signs that there is a chemical reaction are
-color change
-a precipitate (a solid was formed)
