Many of the technological advances over the last 50 - 75 years have been in the area of weaponry and warfare, such as atomic/nuclear weapons, radar, biological weapons, etc. these advances have both positive and negative aspects. which statement describes a negative aspect of these advances?
a)the advances in body armor protect individuals and prevent deaths that previously could not be prevented.
b)advances in communication and transportation have made it easier to prevent attacks and rescue those who need be rescued.
c)advances in satellite imagery have made desired targets easy to hit with little destruction of innocent life and property.
d)the lingering radiation after detonation of atomic weapons destroys the land and continues to harm people and animals long after the blast.

The lingering radiation after detonation of atomic weapons destroys the land and continues to harm people and animals long after the weapon is gone. The other choices are advances that have helped to prevent the loss of life and property.

So the answer is D.) The lingering radiation after detonation of atomic weapons destroys the land and continues to harm people and animals long after the blast.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
