Answer:
The acceleration will be 140 meter per second
Explanation:
Force F = mass m × acceleration a
If F = 42 N and m = 0.30 kg
Then  acceleration a = F/m
a = 42/0.30
a = 140 m/s

The magnetic field of the wire will be directed towards west. Using right thumb rule one can get the direction of field lines.
 
        
             
        
        
        
Answer:
You could use newton’s second law to calculate the force applied to an object if you knew the objects mass and its <u>acceleration.</u>
Explanation:
By, Newtons second law, the force applied on an object directly varies with the acceleration caused and the mass of the object.
This is given by :

Where  represents force applied on the object ,
 represents force applied on the object ,  represents mass of the object and
 represents mass of the object and  represents the acceleration.
 represents the acceleration.
In order to calculate force applied on object we require the mass of the object and its acceleration. The force can be calculated by finding the product of mass and acceleration of the object.
