Answer:
b. Tall oak trees
Explanation:
In order for the owner to be able to have energy benefit for the home in a place with hot summers and cold winters, the most practical thing would be to have tall oak trees in front of the large glass windows on the southern side. The reason for this is that the oak trees will be beneficial in both seasons. During the hot summers, the oak trees will provide a lot of shade, thus lowering the temperature on the southern side where the large glass windows are. During the winter, the oak trees will have no leafs on them, meaning that the southern side will be able to get the needed sunlight in this period. We come to a situation where the oak trees will reduce the energy spending for cooling down in the summer, and it will reduce the energy spending for warming up in the winter.

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.
