When magnetic field lines and surface area are perpendicular to each other.
The final velocity is 0 and the acceleration is gravity. Vf=Vi+at because gravity opposes the motion it will be -g
0=250-gt
gt=250 ....g=10
t=25sec
Answer:
The equation a=F/m or the acceleration is equal to the net force of an object divided by that object's mass, is an equation derived and explained by Sir Issac Newton's second law of motion. Newton's second law of motion states that the force of an object is equal to the mass times the acceleration of that object.
Answer:
Explanation:
The acceleration due to gravity on earth is regardless of the mass of the object. This means, in the absence of air resistance, both a 3000 kg object and a 300 kg will accelerate at the same rate of towards earth.
The reason the acceleration due to gravity is the same for all masses is that by grace of nature, the inertial mass 
of the object from 
equals the gravitational mass from 
, resulting
which is the acceleration that only depends on the mass of earth and its radius, and not on the mass of the object.
