The equation for photosynthesis is 6h2o (water) + 6co2 (carbon dioxide) + light energy → c6h12o6 (glucose) + 6o2 (oxygen). when first discovered, scientists were trying to decide if the oxygen in the product came from carbon dioxide or water. which statement describes how scientists traced the path of oxygen?
they used a radioactive isotope and tracked it with a becquerel counter.
they used a radioactive isotope and tracked it with a geiger counter.
they used a stable isotope and tracked it with a becquerel counter.
they used a stable isotope and tracked it with a geiger counter.

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.
