Answer:
Negative acceleration occurs when an object speeds up in the negative direction.
Positive acceleration occurs when an object speeds up in the positive direction.
Explanation:
This might be wrong but I get some points for a answer..
The relationship between the voltage and the current in the circuit is:

where

is the voltage difference, R the resistance of the circuit (and therefore, the resistance of the battery) and I the current flowing in the circuit. By using I=19 A and

, we can find the internal resistance of the battery:

The hotter an object is, the more infrared radiation it emits. Infrared radiation is a type of electromagnetic radiation, which involves waves rather than particles. This means that, unlike conduction and convection, radiation can even pass through the vacuum of space.
Idk no idea none zero sorry hope someone know more than me
