Venn diagrams are used for comparing and contrasting topics. The overlapping sections show characteristics that the topics have in common, and the sections that are unique to each topic show the characteristics that apply to only that topic. This Venn diagram is comparing mechanical and electromagnetic waves. 2 circles with an overlap. The left circled is labeled Mechanical Wave with further labels Carry Energy Through Matter and Examples: Ocean Waves and Sound Waves. The right circle is labeled Electromagnetic Wave with further labels Carry Energy Through Space and Examples: Light and X-ray. What could be put into the center section of this Venn diagram? “Carry energy through space” and “Follow a pattern” “Carry energy” and “Follow a pattern” “Carry energy through space” and “Can be heard” “Carry energy” and “Can be heard”

3x + 2x = both people using the same measure of like 5x = x= 25 meters per second. 25ms. it takes them 4 seconds to

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)
