Answer:
Answer
Advantages of alcohol over Mercury
(a) Freezing point of alcohol is −117∘
C and hence can record very low temperature For example in Arctic and Antarctic regions temperature may fall below −80∘
C which cannot be measured by mercury thermometer because mercury freezes at−39 ∘ C
(b) The expansion of alcohol per degree rise in temperature is much more around six times more then that of mercury and hence is more sensitive
(c) it can be coloured brightly by adding some dye in it and hence is easily detectable

The key variable that different the two type of jumps is direction of motion.
<h3>
High Jump</h3>
A high jump involves vertical upward upward motion that is limited by gravity.
The maximum height reached during a high jump is given as;
H = vt - ¹/₂gt²
<h3>Long Jump</h3>
A long jump involves horizontal distance that is not affected by gravity.
The horizontal distance traveled during a long jump is given as;
H = vt
Thus, the key variable that different the two type of jumps is direction of motion.

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.
