Answer:182.25 joules
Explanation:
Mass=0.18kg
Velocity=45m/s
Kinetic energy=(mass x(velocity)^2)➗2
Kinetic energy=(0.18 x 45^2) ➗ 2
Kinetic energy=(0.18x45x45) ➗ 2
Kinetic energy=364.5 ➗ 2
Kinetic energy=182.25
Kinetic energy=182.25 joules
Plant Roots. The root system of a plant constantly provides the stems and leaves with water and dissolved minerals. In order to accomplish this the roots must grow into new regions of the soil. The growth and metabolism of the plant root system is supported by the process of photosynthesis occurring in the leaves.
