if the atmosphere is unstable and has strong winds, then the emissions from a smoke stack will ____________.
Ket [755]

When the air is unstable or the atmosphere is unstable this means there is a difference between high pressure and low pressure. The capacity to transport and disperse pollution will be more or higher.

  • The noxious gas like the Sulphur dioxide, nitrogen oxide, carbon oxide, and monoxide that results in urban smog will rise and spread more quickly. This will lead to the unblocking of sunlight.
  • The gases originating from the boiler and other places where the combustion occurs will not adversely affect the environment.

How does lava travel
RSB [31]
Lava flows are the least hazardous of all processes in volcanic eruptions. How far a lava flow travels depends on the flows temperature, silica content, extrusion rate, and slope of the land. A cold lava flow will not travel far and neither will one that has a high silica content. Such a flow would have a high viscosity<span> (a high resistance to flow). A basalt flow like those in Hawai'i have low silica contents and low viscosities so they can flow long distances. Such a flow can move as far away as 4 km from its source and have a thickness of 10 m (Bryant, 1991). These flows can move at rates of several kilometers per hour (Scott, 1989). </span><span>More silica-rich flows can move as far away as 1.3 km from their sources and have thicknesses of 100 m (Bryant, 1991). These flows can move at rates of a few to hundreds of meters per hour (Scott, 1989). If a lava flow is channelized or travels underground in a lava tube then the distance it travels is greatly extended.</span>

2. How much Potential Energy is gained when a 1250 N mass is raised a vertical distance of<br>35 m?​
vichka [17]

Potential Energy

The potential energy gained is 43750 J

Explanation:

Potential energy is the energy by virtue of an object's position relative to the ground ie, the height of the other object.

For example, an object has more potential energy when it is on top of a two-story building than it does resting on the ground. That's because the object's relative position to the Earth gives it more energy.

Potential Energy is defined as

Potential energy = Mass * height

Given Mass M = 1250 N

Given height h = 35 m

So the potential energy = 1250 * 35 = 43750 J

Thus the potential energy is 43750 J
