Sonja [21]

The principle of uniformitarianism states that geologic processes that we observe today occurred in the same way in the past. The correct option among all the options that are given in the question is the last option. Incidents such as floods, hurricanes and huge storms have not occurred only in the present time, but it has been occurring in the past as well.

For the game of interstellar baseball, teams have used robotic enhancements to allow superhuman feats. Consider a pitcher who ca

ziro4ka [17]

Answer:

The baseball would seem to be traveling with a velocity 0.98918c of 98.92% of the speed of light as seen from the Earth.

Explanation:

This problem involves the relativistic effects. The pitcher throws the ball with a velocity u' which is 65% of the speed of light c i.e. u' = 0.65c

The velocity V of the spaceship in which he is practicing is 95% of the speed of light. Therefore V = 0.95c

So if the ball is thrown in the same direction as the direction of the spacecraft's motion, then classically, the velocities would add up and exceed the speed of light. But we know that this is not possible. It is prohibited by the special theory of relativity. So we need to consider the relativistic addition of velocities to calculate the velocity (u) of the ball as seen from the Earth.

The formula for relativistic addition of velocities is expressed below,

$u=\frac{V+u'}{1+\frac{Vu'}{c^2}}$

We know that u' = 0.65c and V = 0.95c. now we can calculate u which is the velocity of the baseball as seen from Earth as follows

$u=\frac{0.95c+0.65c}{1+\frac{0.95c\times 0.65c}{c^2}}$

$u=\frac{1.6c}{1+\frac{0.6175c^2}{c^2}}$

$u = \frac{1.6c}{1.6175}$

u = 0.98918c

So the baseball would seem to be traveling with a velocity 0.98918c of 98.92% of the speed of light as seen from the Earth.

According to the geological time scale, what evolved after the first insects evolved.

Ilia_Sergeevich [38]

Answer:

According to the geological time scale, the species of reptiles evolved after the first insects evolved.

Explanation:

Both, the species of reptiles and the species of insects evolved in the same period called the Paleozoic period.

But out of these two, insects evolved first. There are solid pieces of evidence available to prove that the insects existed way before reptiles did.

It is found that the species of reptiles, which ultimately feed on insects, were the first to evolve after the insects.
