Answer:
- The separation will be spacelike.
- The first event can't cause the second event, as there exist an frame of reference in which both happens at the same time, in different positions, so, if there were causally connected, it will imply an instant connection, this is faster than light.
Explanation:
We can define the separation between two events (using the + - - - signature) as :
where the separation will be lightlike if is equal to zero, timelike if is positive and spacelike if is negative.
For our problem
So the separation will be spacelike, and the first event can't cause the second event, as there exist an frame of reference in which both happens at the same time, in different positions, so, if there were causally connected, it will imply an instant connection, this is faster than light.
Answer:
See explanation below
Explanation:
If we are talking about the kinetic energy of the cylinder of oxygen:
The kinetic energy possessed by any object is given by
where
m is the mass of the object
v is its speed
In this case, we have one cylinder carried by a car and one standing on a platform: this means that the speed of the cylinder carried by the car will be different from zero (and so also its kinetic energy will be different from zer), while the speed of the cylinder standing on the platform will be zero (and so its kinetic energy also zero). Therefore, the kinetic energy of the cylinder carried by the car will be larger than that standing on a platform.
Instead, if we are talking about the kinetic energy due to the random motion of the molecules of oxygen inside the cylinder:
The kinetic energy of the molecules in a gas is directly proportional to the absolute temperature of the gas:
where k is called Boltzmann constant and T is the absolute temperature of the gas. Therefore, we see that K does not depend on whether the gas is in motion or not, but only on its temperature - therefore, in this case there is no difference between the kinetic energy of the cylinder carried by the car and that standing on the platform (assuming they are at the same temperature)
Through vibration when it vibrates
it transfer momentum.
How the tectonic plate movement relates to the continental drift is tectonic plates often move a part and away from one another and lying a top of those plates (continental plates) are continents. The continents, in a way, ride on top of the continental plates and drift towards or apart from each other. In the time of Pangaea, all continents were all squished and packed together, but due to the movement of tectonic plates and the processes of the mid-Atlantic ridge (an exposed area in the lithosphere where new sea-floor is formed), what we know as the Atlantic ocean began to spread the super continent in half and apart. This area filled with water and became the Atlantic Ocean over the course of millions and millions of years. This movement of sea-floor spreading began to spread the continents of the Americas, Europe + Africa from each other, and the continental plate along too began to drift away from each other. Tectonic plates move with the help of convection currents occuring in the mantle.
I'm not sure of how much this has helped. I do take geography so we talked a lot about plate tectonics.
