Answer:
Explanation:
The difference of electric potential between two points is given by the formula 
, where <em>d</em> is the distance between them and<em> E</em> the electric field in that region, assuming it's constant.
The electric field formula is 
, where <em>F </em>is the force experimented by a charge <em>q </em>placed in it.
Putting this together we have 
, so we need to obtain the electric force the charged ball is experimenting.
On the second drop, the ball takes more time to reach the ground, this means that the electric force is opposite to its weight <em>W</em>, giving a net force 
. On the first drop only <em>W</em> acts, while on the second drop is <em>N</em> that acts.
Using the equation for accelerated motion (departing from rest) 
, so we can get the accelerations for each drop (1 and 2) and relate them to the forces by writting:
These relate with the forces by Newton's 2nd Law:
Putting all together:
Which means:
And finally we substitute:
Which for our values means:
The car's (average) acceleration would be
The car's position over time would be given by
so that after 2.4 seconds, the car will have traveled a distance of
Reverse faults is the most best answer
Sry,I only know the answer of q2
Chlorine is a non metal because it is bad conductor of heat and sodium is a metal because it is good conductor of heat.
The 3 ways in which metal is different from non metal are given below:
1)metal are good conductor of heat but nonmetal are bad conductor of heat.
2)metals are malleable but non metal aren't malleable.
3)metals are generally ductile but non metal aren't ductile.
Hope it will helpyou!
