Lucas has a cup of hot tea. its temperature is 80oc. to cool it off, lucas has put an ice cube in the tea. the temperature of the ice cube is 0oc. the cup of tea with the ice cube sits on a table, and the air around it is 25oc. which of the following correctly describes how heat will flow in this situation?

The answer is frictional force

The figure is missing but we can answer anyway.the correct answer is "releasing the string". in fact, when the person is holding the bow and the arrow, the kinetic energy of the arrow is still zero (because the arrow is not moving). the moment the arrow is released, it acquires a velocity v, so its kinetic energy will become different from zero: where m is the mass of the arrow and v its velocity.  all the other options, instead, do not increase the kinetic energy of the system: -  pulling farther back on the string : this will just increase the elastic potential energy of the system-  holding the arrow higher: this will increase the gravitational potential energy of the system (which is given by u=mgh, where h is the height above the ground)-  decreasing the mass of the arrow: this will decrease the gravitational potential energy of the system (which is given by u=mgh, where m is the mass)

Hi.the measurement  amperes represents the rate at which current flows.it's like the measurement of water flowing through a pipe.~
