YALL PLEASE PLEASE HELP IF YOU KNOE THE ANSWER TO BOTH OF THEM IT WILL BE VERY NICE PLEASE HELP

2.5m/s²

Force  = mass x acceleration  

Explanation:

Given parameters

Mass  = 200kg

Force  = 500N

Unknown:

Acceleration  = ?

Solution:

According to the Newton's second law of motion "the constant force applied on a massive body causes it to accelerate".

 Mathematically;

    Force  = mass x acceleration  

Now insert the parameters and solve;

   Acceleration  =  

   Acceleration =   = 2.5m/s²

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.
