The spring scale reads  

Explanation:

From the question we are told that

      The first force is  

      The acceleration by which the cart moves to the right is  

      The mass of the cart is  m  = 3.231  kg

Generally the net force on the cart is  

This net force is mathematically represented as

So  

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
