Answer:

Galvanometer

Explanation:

The device used to detect and measure current and voltage in a circuit is known as a galvanometer. It is based on the principle that a current carrying coil rotates which is suspended in a magnetic field.

Torque acts when a current carrying coil is kept in a magnetic field. It makes the needle of the galvanometer to deflect. The galvanometer is used as ammeter when a low resistance is connected in parallel and as voltmeter when high resistance is connected in series.

When you drink cold water, your body must expend metabolic energy in order to maintain normal body temperature (37° C) by warmin
Papessa [141]

Answer:

The number of liters of ice water is 11 L

Explanation:

Given data:

normal body temperature = 37°C

temperature of the ice water = 0°C

Cwater = specific heat of water = 4186 J/kg °C

Suppose the person drinks 1 L of cold water, then, the mass is 1 kg

The heat is:

Q_{water} =mC_{water} (T_{ice} -T_{body} )=1*4186*(0-37)=-154882J

The sign (-) indicates the energy lost by the metabolic process. If the Qwalk is 390 kilocalories, then the number of liters of ice water is equal to:

n=\frac{Q_{walk} }{Q_{water} } =\frac{390*4186}{154882} =10.54=11L
