The total energy of the system is 88.2 J
Explanation:
The total (mechanical) energy of an object is given by:
where
PE is the potential energy
KE is the kinetic energy
At the starting point, the object is at rest: this means that its kinetic energy is zero, so all its energy is potential energy, which is given by
where
m is the mass of the object
g is the acceleration of gravity
h is the height of the object
In this problem, we have (at point A):
m = 3.0 kg
h = 3.0 m
Substituting, we find:

Answer:
The correct answer is D)
Explanation:
When an electric magnet is brought near a cord with an electric current, the cord will most likely deflect away from the magnet because electric fields flowing through a wire generates its own magnetic field.

A good engineer will create an outline that meets the useful necessities of the venture and after that play out an anxiety examination to get certainty that the tower will be sheltered under the normal scope of working conditions. By then, the outline will be tastefully satisfying to engineers. On the off chance that the customer needs something all the more stylishly cleaned, he may need to utilize a plan authority. A designer who puts feel initially is taking a chance with his expert standing.
