write the additive and multiplicative Inverse for minus 6 by 13 The Correct Answer and Explanation is: Additive Inverse of −613-\frac{6}{13}−136​: The additive inverse of a number is the number that, when added to the original number, gives a result of 0. In other words, it is the opposite of the number. For −613-\frac{6}{13}−136​, the

An automobile traveling 91.0 km/h has tires of 78.0 cm diameter. The angular speed of the tires about their axles is: The correct answer and explanation is: To find the angular speed of the tires, we first need to convert the linear speed (91.0 km/h) into a rotational speed. The relationship between linear speed (v),

If you drive at 120 km/h for 6 hours, how far will you go The Correct Answer and Explanation is: To calculate the distance traveled when driving at a constant speed, you can use the formula: Distance = Speed × Time In this case, the speed is 120 km/h, and the time is 6 hours.

How would you explain the charge changes that occur in a neuron during the messaging process?
