Answer:
Explanation:
Let the initial charge on the two spheres are
now we know that the force between them is given as
now when two spheres are connected then final charge on them is given as
now the force between them is given as
now we have
So by solving above two equations we have
Velocidad-es una cantidad vectorial física; Tanto la magnitud como la dirección son necesarias para definirlo.
Answer:
The angular speed is
Explanation:
From the question we are told that
The time taken is
The number of somersaults is n = 1.5
The total angular displacement during the somersault is mathematically represented as
substituting values
The angular speed is mathematically represented as
substituting values
Answer:
5.714 hours / day
Explanation:
<u>Calculate the hours used in that week </u>
120000 / 3000 = 120 / 3 = 40 hours a week
<u>Calculate the amount it is used in one day</u>
40 / 7 = 5.71428571 hours or 5.714 hours/day
Explanation:
the object will begin to move
