Answer:
The answer is A
Explanation:
The octopus’s tentacle keeps moving right after it is bitten off
Explanation:
Eq 2 ) is Equation for force on a charge Q1 due to charge Q2 separated by a distance R .. it is Equation for Coloumb's law !!
Where , k = 1/4π€
Eq 3 ) is Equation for force on mass m1 due to mass m2 separated by distance R .. it is Newton's law of Gravitation
Where , G = universal Gravitation constant
You would have done 240 joules of work on the box.
Work = (force) x (distance)
= (60 newtons) x (4 meters)
= 240 joules .
What you do is, multiply 16.0 and 12.4 together. then multiply that by 40a
