Answer:
W = 5586[J]
Explanation:
Work in physics is defined as the product of force by a distance.

where:
W = work [J]
F = force = m*g [N]
m = mass = 300 [kg]
g = gravity acceleration = 9.81 [m/s²]
d = distance = 1.9 [m]
Now replacing:
![W=m*g*d\\W=300*9.81*1.9\\W=5586[J]](https://tex.z-dn.net/?f=W%3Dm%2Ag%2Ad%5C%5CW%3D300%2A9.81%2A1.9%5C%5CW%3D5586%5BJ%5D)
Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. ... The rubbing of certain materials against one another can transfer negative charges, or electrons.

Answer:
For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. Engineers apply Newton's third law when designing rockets and other projectile devices.
