The formula for exponential population growth is

where
initial population of E.coli i.e 100
k is the rate of population growth i.e 2 as the population doubles
t is the time period i.e 20 minutes
Substituting the given values in above equation, we get -

Weathering is a process that breaks down or changes rocks into smaller
pieces. Various atmospheric aspects are responsible for weathering
processes. Weathering is different from erosion. Erosion is the movement
of rock pieces and sediment from one area to another. Weathering is the
breaking down of rocks and erosion is a wearing away of rocks. There
are two main types of weathering: physical (or mechanical) weathering
and chemical weathering. Quite often, both forms of weathering will
occur together
Physical weathering is also known as mechanical weathering. This type of
weathering occurs when rocks and other landforms are broken down by
physical factors in the environment. These physical factors include
wind, water, sun, ice and temperature changes
They both involve topics related to the natural world, and are both based on empirical evidence. <span />
