The state of matter is an example of a physical property. Why is the state of matter considered a physical property, even though a substance may change between a solid, liquid, and gas? Group of answer choices A. The state of matter depends on the amount of substance present. B. The chemical nature of the substance does not change. C The property can be easily observed D. Solids, liquids, and gases contain different substances from one another

It equals just about 6,300 km per hour each day an week

The figure is missing but we can answer anyway.the correct answer is "releasing the string". in fact, when the person is holding the bow and the arrow, the kinetic energy of the arrow is still zero (because the arrow is not moving). the moment the arrow is released, it acquires a velocity v, so its kinetic energy will become different from zero: where m is the mass of the arrow and v its velocity.  all the other options, instead, do not increase the kinetic energy of the system: -  pulling farther back on the string : this will just increase the elastic potential energy of the system-  holding the arrow higher: this will increase the gravitational potential energy of the system (which is given by u=mgh, where h is the height above the ground)-  decreasing the mass of the arrow: this will decrease the gravitational potential energy of the system (which is given by u=mgh, where m is the mass)
