3. Two cars are headed east on a straight road. In the reference frame of the road, Car A is traveling at +22 m/s, and car B is traveling at +30 m/s.
a. In the reference frame of car A what is the velocity of car B? what is the velocity of the road?
b. In the reference frame of car B what is the velocity of car A? what is the velocity of the road?

This is what a calorimeter is used for simpler ex, to measure calories in food.

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
