In the united states, almost two-thirds of all liquid hazardous wastes are injected into deep disposal wells.
Hazardous waste is waste that has substantial or potential threats to public health or the environment. Hazardous waste is a type of dangerous goods.
They usually have one or more of the following hazardous traits: ignitability, reactivity, corrosivity, toxicity Listed hazardous wastes are materials specifically listed by regulatory authorities as hazardous wastes which are from non-specific sources, specific sources, or discarded chemical products.
Hazardous wastes may be found in different physical states such as gaseous, liquids, or solids.
A hazardous waste is a special type of waste because it cannot be disposed of by common means like other by-products of our everyday lives.
Depending on the physical state of the waste, treatment and solidification processes might be required.

Answer: a. perigee speed
Explanation:
Firstly, we must define what is Perigee and Apogee:
The apogee is the point in an elliptical orbit around the Earth <u>where a body is furthest from the center of it and according to Kepler's 2nd law the speed of a satellite at this point is the lowest.
</u>
On the other hand, the <u>perigee</u> is the opposite orbital point. <u>It is where a satellite is closest to Earth and its orbital speed is maximum.
</u>
Therefore, if we want to throw an object in such a way that it is orbiting the Earth at the same distance respect to the ground, the minimum speed must be that which is in the perigee.
