Answer:
The required net force has a magnitude of 7200 N
Explanation:
Use Newton's 2nd Law to obtain the answer:

Explanation:
It is given that,
Earth's magnetic field,
Direction of magnetic field, 67.1 degrees below the horizontal, with the horizontal component directed due north.
The magnetic force on the wire per unit length of wire, 
(a) The given scenario is shown in the attached figure as :
Using the right hand rule to find the direction of magnetic force on the wire. By using this rule, we get the magnetic force acting on the wire is in upward direction.
(b) Let I is the current flowing in the wire. The magnetic force is given by the following formula as:



I = 384.61 A
Hence, this is the required solution.
Answer:
Catastrophic theories
Explanation:
The theory of catastrophe is a collection of methods used to analyze and describe the ways in which a system can experience sudden significant behavioral changes when one or more of the variables that govern it are continuously modified.
Georges Louis de Buffon suggested in 1745 the first destructive theory — that a comet pulled material from the Sun to form the planets.
Therefore the answer is -
