To solve this problem we will apply the concepts related to the Magnetic Force, this is given by the product between the current, the body length, the magnetic field and the angle between the force and the magnetic field, mathematically that is,
![F = ILBsin \theta](https://tex.z-dn.net/?f=F%20%3D%20ILBsin%20%5Ctheta)
Here,
I = Current
L = Length
B = Magnetic Field
= Angle between Force and Magnetic Field
But ![\theta = 90\°](https://tex.z-dn.net/?f=%5Ctheta%20%3D%2090%5C%C2%B0)
![F = ILB](https://tex.z-dn.net/?f=F%20%3D%20ILB)
Rearranging to find the Magnetic Field,
![B = \frac{F}{IL}](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7BF%7D%7BIL%7D)
Here the force per unit length,
![B = \frac{1}{I}\frac{F}{L}](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7B1%7D%7BI%7D%5Cfrac%7BF%7D%7BL%7D)
Replacing with our values,
![B = \frac{0.130N/m}{16.5}](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7B0.130N%2Fm%7D%7B16.5%7D)
![B = 0.0078T](https://tex.z-dn.net/?f=B%20%3D%200.0078T)
Therefore the magnitude of the magnetic field in the region through which the current passes is 0.0078T

Answer:
1-An object's velocity will change if a net force acts on the object. (True)
2-In order not to slow down, a car moving at a constant velocity needs a small net force applied. (False)
3- The net force which acts on an object which remains at rest is zero. (True)
4- If an object's speed does not change, no net force is acting on the object.(True)
5- If two objects are under the influence of equal forces, they have the same acceleration. (False)
6- During the collision of a car with a large truck, the truck exerts a greater force on the car than the car exerts on the truck.(False) (Newton Third Law)
<span>110m/72s with a direction toward shore.
or as a decimal
1.5278 m/s with a direction toward shore.
Remember velocity is a VECTOR and not simply a speed, you MUST give a direction when answer a velocity question properly.</span>
