In a thermostat, what property of the bimetallic coil allows it to contract and expand? The two metals absorb different amounts

Reika [66]

Hello!

In a thermostat, the property of the bimetallic coil that allows it to contract and expand is that The two metals absorb different amounts of thermal energy.

This bimetallic coil is used to transform thermal energy into mechanical movement. Two metals with different thermal expansivity are joined together parallelly and the changes of temperature cause bending in different directions depending on if the temperature is rising or descending.

The differences in the thermal energy absorption of the two metals are the basis for the mechanism of this device.

What must the charge (sign and magnitude) of a 1.65 gg particle be for it to remain balanced against gravity when placed in a do

balandron [24]

Answer:

Charge, $q=2.52\times 10^{-5}\ C$ and it is negative.

Explanation:

Given that,

Mass of the charge, $m=1.65\ g=1.65\times 10^{-3}\ kg$

Electric field, E = 640 N/C

To find,

Charge

Solution,

The electric force and the force of gravity are balanced in the electric field. It is given by :

$qE=mg$

$q=\dfrac{mg}{E}$

$q=\dfrac{1.65\times 10^{-3}\times 9.8}{640}$

$q=2.52\times 10^{-5}\ C$

Since, the electric field is in downward direction. The force must be upward direction s that the charge is negative.

Set up a parallel circuit with three resistors. Set up the battery to be 9 V, one resistor at 10 Ohms, the other at 21 Ohms, and

valina [46]

In a parallel circuit, the equivalent resistance is the reciprocal of (the sum of the individual reciprocals).

1/R = 1/10 + 1/21 + 1/13

1/R = 0.225 mhos

R = 4.45 ohms

I = V / R

The total current out of the battery is

I = (9v)/(4.45ohms)

I = 2.02 Amperes

As the total current leaves the battery, it splits into 3 paths, and each resistor gets part of it. The 10ohm resistor gets the most current; the 21ohm resistor gets the least current. After flowing through the resistors, the 3 currents join and add up to 2.02 Amperes again, and the same current returns to the battery.

Each resistor has the same 9v of EMF across it.
