Answer:
10.89 J.
Explanation:
The following data were obtained from the question:
Mass (m) = 12.5 kg
Velocity (v) = 1.32 m/s
Work done =?
To obtain the workdone, we shall determine the kinetic energy of the object since work and energy has the same unit of measurement. This is illustrated below:
Mass (m) = 12.5 kg
Velocity (v) = 1.32 m/s
Kinetic energy (K.E) =?
K.E = ½mv²
K.E = ½ × 12.5 × 1.32²
K.E = 6.25 × 1.7424
K.E = 10.89 J
The kinetic energy of the object is 10.89 J. Hence, the workdone in bringing the object to rest is 10.89 J.

water droplets that form together with a dust on the atmosphere.
Cirrus, cirrostratus and cirrocumulus are made up of ice crystals. It forms
when the water vapor goes condensation at high altitudes in where the pressure
on the atmosphere reaches the point from 600 mbar at 4000 meter above the sea
level up to 200mbar at 12 000m above sea level. These clouds form
thunderstorms, cyclones and contrails (a manmade cloud).</span>

To solve this problem we will apply the concept of voltage given by Coulomb's laws. From there we will define the charges and the distance, and we will obtain the total value of the potential difference in the system.
The length of diagonal is given as
The distance of the center of the square from each of the corners is
The potential electric at the center due to each cornet charge is
The total electric potential at the center of the given square is
Al the charges are equal, and the distance are equal to a, then
Therefore the correct option is E.
