<span>The least common shape for a galaxy is cluster.
Galaxy, by definition, is an arrangement composing of stars, planets, gasses
and everything more that can be seen in the space. There are three types of
galaxies and they are elliptical, spiral and irregular. Spherical could be
applicable as elliptical if you got to choose only one on the choices above. Example
of spiral galaxy is the Milky Way galaxy where our Solar system is currently
located according to the scientists. </span>
A because when gravity and the force are equilibrium it tend to be equal or stay at rest or constant velocity. But when the force of a plane is less than the force of gravity it will go down to the ground. Unless when the force of a plane is greater than the force of gravity, the plane will move upward at increasing rate.
Hope this helps
Answer:
Explanation:
First last of thermodynamics, just discusses the changes that a system is undergoing and the processes involved in it. It explains conservation of energy for a system undergoing changes or processes.
Second law of thermodynamics helps in defining the process and also the direction of the processes. It tells about the possibility of a process or the restriction of a process. It states that the entropy of a system always increases.
For this to occur the energy contained by a body has to diminish without converting to work or internal energy. So imagine a machine which works with less than efficiency, this means there are losses but they don’t show up anywhere. But the energy is obtained from a higher energy source to lower.
The easy way to do this is with an imaginary device that extracts zero-point energy to heat a quantity of gas. Energy is being created, so the first law is violated, and the entropy of the system is increasing as the gas heats up.
First law is violated since the energy conversion don't apply but the direction of work is applied so second law is satisfied.
Organisms must maintain a pH level of seven. Seven is known as neutral in the pH scale. It has the same amount of balanced bases and acids. Hope this helps:)
Answer:
is the rate of change of its position of an object with respect to a frame of reference, and is a function of time. Velocity is equivalent to a measure of an object's speed and direction of motion.
