Answer:
it would be a bad thing because if one person controlled the government then there would only be one mind in charge.
Explanation:
Acceleration = (final velocity - initial velocity) / time
= (35-65)/10
= -3 m/s2
Here when an object is placed on the level floor then in that case there are two forces on the object
1). Weight of object downwards (mg)
2). Normal force due to floor which will counterbalance the weight (N)
so when no force is applied on the box at that time normal force is counter balanced by weight.
Now here it is given that A person tried to lift the box upwards
So now there are two forces on the box
1). Applied force of person
2). Normal force due to ground
So now these two forces will counter balance the weight of the crate
So we can write an equation for force balance like
given that
here
m = 30 kg and
g = acceleration due to gravity = 10 m/s^2
now from above equation
So force applied by the person must be 150 N
To calculate the force between two negative charges, we use the formula which is given by the Coulomb`s Law as
Here, and are the charges on the pith balls, r is the separation between the charges and k is constant and its value is .
Given and .
Substituting these values in above formula we get,
Thus, the repulsive force between two pith balls is .
