Answer:

None of these is correct.

Explanation:

The average speed can be derived from the sum of the total distance traveled and the total time taken.

 Total distance = 4.9 + 1.9  = 6.8

  Total time taken  = 33 + 39  = 72

So;

 Average speed  = \frac{total distance}{total time}  = \frac{6.8}{72}   = 0.014

None of the answer choices given is correct.

A 9.800 mol sample of nitrogen gas is maintained in a 0.8166 L container at 301.8 K. What is the pressure in atm calculated usin
cluponka [151]

Answer:

P = 359.8 atm

Explanation:

The van der Waals' equation relates the properties of a gas, introducing constants "a" and "b" in order to consider gases as real gases. The equation is:

(P+a.\frac{n^{2} }{V^{2} } ).(V-nb)=n.R.T

where,

P: pressure

a: correction factor for intermolecular forces

V: volume

b: correction factor for molecules' volume

n: moles

R: ideal gas constant

T: absolute temperature

(P+\frac{1.390L^{2}atm}{mol^{2}}.\frac{(9.800mol)^{2}}{(0.8166L)^{2}}).(0.8166L-9.800mol.\frac{3.910 \times 10^{-2}L}{mol})=9.800mol \times \frac{0.08206atm.L}{mol.K} \times 301.8K\\(P + 200.2atm).(0.4334L) = 242.7atm.L\\P=359.8 atm

g According to the Third Law, the action and reaction forces are exactly equal in magnitude and in opposite directions. So when
torisob [31]

Answer:

One way to look at this is to consider the forces acting on any point in a string.

For a very small portion of string F = M a must still hold. As M approaches zero the small portion of string would have to approach infinite acceleration if the net force on that portion of string were not zero.

One generally considers the net force acting on the center of mass of an object not  the individual forces acting on each infinitesimal mass composing

the object.

What is the difference between the parts of the plot with positive slope and the parts with negative slope?
zalisa [80]

The difference between the parts of the plot with positive slope and the parts with negative slope can be found below.

<h3>What is a slope?</h3>

A slope in a graph is the ratio of the vertical and horizontal distances between two points on a line. Slope shows both steepness and direction of values.

A slope can either be positive or negative depending on the relationship between the variables being plotted.

A positive slope means that the variable are directly related while the negative slope means that two variables are negatively related.

A positive slope further means that the line moves upward when going from left to right on the graph while with the negative slope, the line moves down when going from left to right.
