A cylindrical tank filled to a height of 25 feet with tribromoethylene has been pressurized to 3 atmospheres (Psurface= 3 atmospheres). The total pressure at the bottom of the tank is 5 atmospheres. Determine the density of tribromoethylene in units of kilogrms per cubic meter.

Explanation:

Given:

height of the given liquid in the tank,

pressure at the surface of the liquid,

pressure at the bottom of the liquid,

So the pressure due to height of the liquid column:

Now as we know that the pressure due to the height of liquid column is given as:

where:

density of the liquid

acceleration due to gravity

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
