Explanation:
-body temp: when cold, erector muscle contract, hair raise, vasoconstriction occurs, sweat production reduces, muscle shiver to enhance metabolism, and thyroid gland secret more thyroxine to enhance metabolism
-water potential balance: when we are thirsty, pituitary gland secret more ADH, kidney tubules become more permeable to water, so more water re-absorbed, less urine produced, retaining more water.
Answer:
Option C is correct.
The resistance of the TV = 68.6 ohms.
Explanation:
According to Ohm's law, the voltage across a device is equal to the product of the current through the device and the resistance across the device.
Since electrical appliances are setup in parallel connection, the voltage across the TV and the PlayStation is the same and is 120 V.
V = IR (From Ohm's law)
V = voltage across the TV = 120 V
I = current flowing through the TV = 1.75 A
R = Resistance of the TV = ?
120 = 1.75 × R
R = (120/1.75) = 68.57 ohms = 68.6 ohms.
