The combined mass of Danny+skateboard is 72.5 kg
Explanation:
We can solve the problem by using Newton's second law of motion:
where:
F is the net force applied on Danny and the skateboard
m is the mass of Danny+skateboard
a is the acceleration
Here we have the following data:
F = 29 N is the force applied
is the acceleration of Danny and the skateboard
Solving for m, we find their combined mass:

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.
