Answer:
2: 20HZ 3:audiable
Explanation:
i guessed and it told me i was right
Explanation:
The net force along the horizontal direction is

where f is the frictional force. We can find the frictional force by looking at the vertical forces acting on the couch:

From the definition of frictional force,


Therefore, the net force on the couch is

The relation between volume and temperature is direct, this is the higher the temperature the higher larger the volume.
Therefore, if you want that your gas occupies a larger volumen, you should increase the temperature, assuming other conditions (pressure and number of moles) remain unchanged.
The new temperature may be calculated using the proportion:
V1 / T1 = V2 / T2
=> T2 = V2 * T1 / V1
T1 and T2 are in absolute degrees, so T1 = - 73 + 273.15 = 200.15 K
=> T2 = 360 ml * 200.15 K / 210 ml = 343
Answer: the temperature should be increased to 343 K
A. The object is made of stone or metal, which always sink.
B. The force of gravity is stronger than the buoyant force.
C. The buoyant force is stronger than the force of gravity.
D. The mass of the item is greater than its gravity
The answer is C
