Geologic time scales are essential tools for geologists and biologists alike as a result of they assist show the history of the whole world in terms of relationships between totally different plate movements.

Explanation:

Time could be an important variable in earth science, as a result of the exact timing of spatially separated events permits the United States of America to reconstruct the surface and surface conditions of the ancient earth. ... geological time spans area unit significantly more difficult to grasp than historical time spans as a result of they're therefore incredibly long.

In the geological timescale, time is usually divided on the premise of the earth's biotic composition, with the Phanerozoic aeon(i.e. the era, Mesozoic era and cenozoic Eras) representing the amount of Earth's history with advanced life forms, and therefore the Pre Cambrian (or Proterozoic and Hadean Eras.

Which scientist described an atom made of a solid positively charged substance with electrons dispersed throughout it?.

The scientist that described an atom made a solid positively charged substance with electrons dispersed throughout it was: Ernest Rutherford

In 1911 Ernest Rutherford proposed his atomic model in which he considered the atom as a positively, densely charged center called a nucleus in which the electrons circulate around the core with a negative charge.

The atom is the smallest part of the composition of matter, it is indivisible and is composed of a nucleus that has protons and neutrons, and around the nucleus there are the electrons.

A hose directs a horizontal jet of water, moving with a velocity of 20m/s, on to a vertical wall. The

Force is defined as the rate of change of momentum.
The initial amount of momentum is $mv$ because water stops when it hit the wall total change of momentum must be $\Delta p=mv$ .
Now let's calculate the force.
$F= \frac{dp}{dt}=\frac{d(mv)}{dt}=\frac{dm}{dt}v$
We need to find $\frac{dm}{dt}$ . This is the amount of water hiting the wall per second.
$\frac{dm}{dt}=\rho Av$
Our final formula would be:
$F=\rho Avv=\rho Av^2$
And now we can calculate the answer:
$F=1000\cdot5\cdot 10^{-4}\cdot(20)^2=200 N$
