A rift valley is formed on a divergent plate boundary, which means that the two plates are
a. moving apart - this is the correct answer!
Rift valleys are often filled with lakes. For example, some scientists suggest that the Dead Sea lies in such a rift valley. Other such lake includes Lake Albert in Congo and Uganda.

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,

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 = 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.

I have this same question what is it
Answer:
John Adams
Explanation:
Like his father, John Adams, President John Quincy Adams did not attend the inauguration of his successor. President-elect Andrew Jackson arrived in Washington on February 11, 1829. He did not call on President Adams, nor did Adams invite Jackson to the White House. Later that month, President Adams moved to a mansion on Meridian Hill in Washington, D.C., and officially departed the White House on the evening of March 3, the day before the inauguration of President Jackso
