Atemperature sensor has a response time of 2 minutes. you stick the sensor in a refrigerator for a while where the temperature is 0 degrees celsius. and then put it in a room where the temperature is 20 degrees celsius. what will be its temperature after 2 minutes?
part 2) how long (in minutes) does it take for the temperature sensor to reach 18 degrees celsius?

Letter a, because when there are unlike charges they will always attract to each other.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction 

Need more information like a picture

So are u adding some additional catalyst
