Do electrical appliances like heaters, toasters and heating pads have high or low resistance (remember for constant voltage, p =

v^{2} 2 /r)? explain your reasoning.

The correct answer is low resistance.

A heating element's resistance is neither "extremely high" nor "very low." Since the amount of heat produced by the circuit is proportional to the current, the resistance of the heating element must be low enough to draw the necessary current. Thus, low resistance is the general characteristic of electrical devices like warmers, toasters, and heating pads. Any voltage will experience high current if resistance is too low. Current will be low if resistance is too high and voltage is okay. NOTE: Current increases as resistance decreases and decreases as resistance increases while the voltage remains constant, like in an automotive circuit.

Nitella [24]

F = 52000 N

m = 1060 kg

a= F/m = 52000 N/1060 kg = 49.0566 m/s^2

What is the 5 quantitative research problems?<br>​
iogann1982 [59]

Answer:

There are four main types of Quantitative research: Descriptive, Correlational, Causal-Comparative/Quasi-Experimental, and Experimental Research. attempts to establish cause- effect relationships among the variables. These types of design are very similar to true experiments, but with some key differences.

Explanation:

Quantitative research is defined as a systematic investigation of phenomena by gathering quantifiable data and performing statistical, mathematical, or computational techniques.
