What is the mass of 50 n object on earth

The average gravity on Earth is:

Since N represents Newtons and Newtons is a measurement of force we can use the following equation:

Where F is force, m is mass, and a is acceleration.  In this case the acceleration is the gravity acting on the object.  Therefore, F=50N, a=g=9.81m/s^2 and m is to be determined. And so:

Therefore, the mass is approximately 5.1 kg.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
