Conduction occurs more easily between solids and liquids. This is because the particles in gases are A) further apart and move f

valkas [14]

The answer is A. Further apart and move faster.

Conduction in general is the transfer of energy from molecule to molecule through DIRECT CONTACT. In solids and liquids, the molecules are closer to each other; more so in solids than liquids. This enables them to pass energy more quickly. Gas molecules on the other hand are further apart and move faster because they have space to move more freely. Energy does not easily pass on to the next molecule because of the distance between the molecules.

The box of a well-known breakfast cereal states that one ounce of the cereal contains 113 Calories (1 food Calorie = 4186 J). If

mafiozo [28]

Answer:

$m=454.73 kg$

Explanation:

To convert the energy of the cereal to know the weight:

$m*g*h=Q'$

$Cal=0.0179*113 Cal=2.0227Cal$

$Q'=2.0227Cal*\frac{4186J}{1Cal}$

$m*g*h=8467.02J$

$m*g=\frac{Q'}{h}=\frac{8467.02J}{1.90m}$

$m*g=4456.33 N$

Supuse the gravity as a g=9.8m/s^2

$m=\frac{4456.33N}{9.8m/s^2}$

$m=454.73 kg$

On a road trip, a driver achieved an average speed of (48.0+A) km/h for the first 86.0 km and an average speed of (43.0-B) km/h

Bond [772]

A = 15, B = 1
48 + 15 = 63 for the first 86km
43 - 1 = 42 for the remaining 54 km
time = distance/speed
t1 = 86/63 = 1.3651hours
t2 = 54/42 = 1.2857hours
speed = distance/time
s = 140/2.6508
average speed = 52.8km/h
