Answer: The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
Explanation:
The answer is A. Mass is constant, height and width won’t change. So that leaves weight.
This information is valuable because Managers can use this customer data each month to figure out whether a larger or smaller percentage of visitors are buying clothes there.
<h3>What is the percentage of a number?</h3>
It is the relative value that represents the hundredth part of any number for example 2% of any number represents, 2 multiplied by the 1/100th of that number.
A clothes business contains sensors that count the number of customers entering the store and cash registers that count the number of transactions made daily.
Thus, data is useful because Managers may use it to determine if a greater or lesser proportion of customers are purchasing clothing each month. Therefore the correct answer is option A.

Answer:
With the increase in depth, age of layer increases.
Explanation:
According to the law of superposition, the layer of the Earth that is present in the deep is considered as the oldest layer while on the other hand, those layer which is present on the top of all layers is considered as youngest layer of earth. When we move from the top layer towards the bottom layer, the age of layer increases or in other words, when we move upward the age of the layer decreases so label the layers of earth on the basis of this phenomenon.
Answer:
Spectra type M
Explanation:
mass spectrum is simply an intensity vs. m/z (mass-to-charge ratio) plot representing a chemical analysis. Hence, the mass spectrum of a sample is a pattern representing the distribution of ions by mass (more correctly: mass-to-charge ratio) in a sample. It is usually acquired using an instrument called a mass spectrometer. Not all the mass spectra of a given substance are same.
