Answer:

The 20 kg stone traveling at 10m/s

Explanation:

Hi, the kinetic energy is the energy available of the objects in movement.

That energy can be calculated be the next formula:

ec=0.5*m*v^2

Where:

  • ec is the kinetic energy [J]
  • m is the mass of the object [kg]
  • v is the velocity of the object [m/s]

Case A:

ec=0.5*20kg*(10m/s)^2

ec=1000 J

Case B:

ec=0.5*40kg*(4m/s)^2

ec=320 J

Case C:

ec=0.5*30kg*(6m/s)^2

ec=540 J

Case D:

ec=0.5*50kg*(2m/s)^2

ec=100 J

Answer: A 20kg Stone traveling an 10 m/s

Explanation:

The Formula for Kinetic Energy is KE = 0.5 x mv², using this equation you can then find the item with the most Kinetic Energy in Joules (J) 0.5 x 20 x 10 = 200 Joules.

THE CONSTANT MOVING OF AND HELP THE TEMPERATURES AROUND THE EARTH REMAIN ABOUT THE SAME AVERAGE
nika2105 [10]

New analysis through 2014 shows that temperature is once again rising at about the same pace as it did over the second half of the 20 th century. PRESS RELEASE. Using the data that were available at the time (through 2012), the last climate report from the Intergovernmental Panel on Climate Change concluded that there had been no statistically significant increase in global surface temperature

Ainat [17]
Rutherford's atomic structure model was revolutionary. Contrary to J.J. Thompson's "plum pudding" model (which consisted of a solid, even mixture of protons and electrons), Rutherford's model consisted of one small, positively charged, dense nucleus, a layer of empty space, and a layer of negatively charged electrons. He came to this conclusion through his gold-foil experiment. He shot a ray of alpha particles towards the thin gold foil, and to Rutherford's surprise, some of the rays reflected back instead of going straight through the foil as he originally thought.
