Work done = 100J
Distance = 5 meters
Force = ?
Force = 100/5 = 20N
Therefore, the force needed is 20 Newtons

Explanation:
High Pressure
Basically, high pressure occurs in an area if the atmosphere over that particular area becomes heavier. As a result, the heavy air above will come down to the Earth’s surface. And the air present in that area will move away to create space for the heavy air.
Commonly, the warmer months experience high pressure. You’re more likely to enjoy a comparatively dry and stable weather pattern in those months. Besides, you’ll find the skies in high pressure areas very clear. You’ll also feel a gentle breeze there that will cool down the surrounding areas.
Low Pressure
On the other hand, the air above a low pressure area is comparatively much lighter than the air below. As the heavy air on the Earth’s surface cannot go further below, it pushes away the lighter air above. As a result, a vacuum is created on the surface level and the air in the surrounding areas rushes towards it to fill up the void space.
Meanwhile, the rising air starts to cool down and form clouds in the sky. These clouds then come down to the Earth in the form of rain. Sometimes, snow is also formed depending on the temperature of the surrounding areas.
In general, colder months of the year experiences more low pressure situations. By now, you probably can guess why. The cold air on the surface level is heavier than the air above. And these low pressure areas are the reasons behind unstable weather conditions like snow, ice, rain, storm, etc.

<span>The two basic molds are: Expendable
mold and permanent mold. </span>
Molding is a
process where a rigid frame (mold) is being used to manufacture by shaping liquid
or pliable raw materials. However, molding is synonymous to casting; casting is
a process where a liquid metal is delivered into a mold which contains a hollow
cavity of the intended shape.
Expendable mold casting can be classify as
sand, plastics, plaster which make use of non-reusable or temporary molds while Permanent mold casting is a metal
casting process that use reusable molds.
This drug inhibits the growth of bacterial cells but not human cells. This is an example of the selective toxicity of antibiotics.
Folic acid is an essential component for all cells to synthesize nucleic acids (DNA and RNA). Human cells do not synthesize folic acid and they take it through food. Bacterial cells are impermeable to folic acid and hence they need to synthesize their own folic acid.
Antibiotics target the metabolic pathway of folic acid synthesis in bacteria by inhibiting one of the enzymes in this pathway. These drugs are only toxic to bacteria but not to humans because humans do not have the folic acid synthesis pathway and hence they do not get affected by the action of the antibiotic. This is known as the selective toxicity of antibiotics.
These antibiotics are designed in a way to target the infecting agent (bacteria) while rendering minimal or no toxicity to the host (humans).
