<h2 /><h2>✔The matter is stationary on a macroscopic scale—we know that thermal motion of the atoms and molecules occurs at any temperature above absolute zero.) Heat transferred from the burner of a stove through the bottom of a pan to food in the pan is transferred by conduction.</h2>

an 11 ohm resistor and a 6 ohm resistor are connected in series with a battery. the potential difference across the 6 ohm resist
Maru [420]

Two resistors in series are often called a 'voltage divider', because the
total voltage divides in proportion to the resistances.

The total resistance in the string across the battery is (11 + 6) = 17 ohms.

-- The full battery voltage appears across 17 ohms.
-- The voltage across the 11-ohms is (11/17) of the battery, and
-- the voltage across the 6-ohms is (6/17) of the battery. 

                                  (6/17) x (B) = 9 volts

Multiply each side by (17/6) :      B = (9 volts) x (17/6)  =<em>  25.5 volts </em>.

By the way, in case you care or are asked . . .

-- The current in the whole series loop is  B/R = 25.5 / 17 = 1.5 Amperes
-- The power drawn from the battery is   B²/R = (25.5)²/17 =  38.25 watts
-- The power dissipated by the 6-ohm resistor is  V²/R = 9²/6 = 13.5 watts
-- The power dissipated by the 11-ohm resistor is I²R = (1.5)² (11) = 24.75W
-- (Check:  13.5W + 24.75W = 38.25W     yay! )
-- If they're just composition units hanging out in the air, then both resistors
are getting quite warm.

A 5.22-kg object passes through the origin at time t = 0 such that its x component of velocity is 5.10 m/s and its y component o
Mamont248 [21]

The magnitude of the object's velocity is

         √ (5.1² + 2.82²)  =  √ (33.9624)  =  5.828 m/s .

Kinetic energy = (1/2) (M) (speed²)

                       =  (1/2) (5.22 kg) (5.828 m/s)²

                       =     (2.61 kg) (33.9624 m²/s²)

                       =          88.64    kg-m²/s²

                       =          88.64  Joules

A class of students performed the heat transfer experiment shown in the picture. In the experiment, three plastic dishes were pa
balandron [24]

The method of heat transfer used in the experiment is radiation.

Radiation is a method of heat transfer in which there is no material medium that conveys heat. Heat travels through empty space and causes the temperature of objects to rise.

In this case, there was no material medium that conveyed heat from the lamp to the dishes containing the plants. Heat from the lamp traveled through space and reached the dishes. This is an example of heat transfer via radiation.
