Answer:

The slope of the graph is what you need. That tells you the speed not the velocity. In order to find the velocity you would also need to know the direction of the motion.

The volume of a gas decreases from 15.7 mºto 11.2 m3 while the pressure changes from 1.12 atm to 1.67 atm. If the
Svetlanka [38]

Answer:

Approximately 261\; \rm K, if this gas is an ideal gas, and that the quantity of this gas stayed constant during these changes.

Explanation:

Let P_1 and P_2 denote the pressure of this gas before and after the changes.

Let V_1 and V_2 denote the volume of this gas before and after the changes.

Let T_1 and T_2 denote the temperature (in degrees Kelvins) of this gas before and after the changes.

Let n_1 and n_2 denote the quantity (number of moles of gas particles) in this gas before and after the changes.

Assume that this gas is an ideal gas. By the ideal gas law, the ratios \displaystyle \frac{P_1 \cdot V_1}{n_1 \cdot T_1} and \displaystyle \frac{P_2 \cdot V_2}{n_2 \cdot T_2} should both be equal to the ideal gas constant, R.

In other words:

R = \displaystyle \frac{P_1 \cdot V_1}{n_1 \cdot T_1}.

R =\displaystyle \frac{P_2 \cdot V_2}{n_2 \cdot T_2}.

Combine the two equations (equate the right-hand side) to obtain:

\displaystyle \frac{P_1 \cdot V_1}{n_1 \cdot T_1} = \frac{P_2 \cdot V_2}{n_2 \cdot T_2}.

Rearrange this equation for an expression for T_2, the temperature of this gas after the changes:

\displaystyle T_2 = \frac{P_2}{P_1} \cdot \frac{V_2}{V_1} \cdot \frac{n_1}{n_2} \cdot T_1.

Assume that the container of this gas was sealed, such that the quantity of this gas stayed the same during these changes. Hence: n_2 = n_1, (n_2 / n_1) = 1.

\begin{aligned} T_2 &= \frac{P_2}{P_1} \cdot \frac{V_2}{V_1} \cdot \frac{n_1}{n_2}\cdot T_1 \\[0.5em] &= \frac{1.67\; \rm atm}{1.12\; \rm atm} \times \frac{11.2\; \rm m^{3}}{15.7\; \rm m^{3}} \times 1 \times 245\; \rm K \\[0.5em] &\approx 261\; \rm K\end{aligned}.

A pressure is applied to 2L of water. The volume is observed to decrease to 18.7 L. Calculate the applied pressure.
lakkis [162]

Answer:

Applied pressure is 1.08 10⁵ Pa

Explanation:

This exercise is a direct application of Boyle's law, which is the application of the state equation for the case of constant temperature.

PV = nR T

If T is constant, we write the expression for any two points

Po Vo = p1V1

From the statement the initial pressure is the atmospheric pressure 1.01 10⁵ Pa, so we clear and calculate

1 Pa = 1 N / m2

P1 = Po Vo / V1

P1 = 1.01 10⁵ 20/18.7

P1 = 1.08 10⁵ Pa

A bird travels 1.70 x 10^4 km south then turns around and travels 6.00 x 10^2 north. He then turns around again immediately and
Citrus2011 [14]

The distance the bird flies is (17,000 + 600 + 14,400) = 32,000 km.

His average speed is (32,000 km)/(122 days) = 262.3 km/day.


The bird ends up (17,000 - 600 + 14,400) = 30,800 km north
from where he started.

His average velocity is (30,800 km)/(122 days) = 252.5 km/day north .

Calculate the amount of gravitational potential energy at the top of each hill
Marizza181 [45]
The gravitational potential energy has the formula:
PE = mgh
where PE is in joules
m is the mass of the object in kg
g is the acceleration due to gravity
h is the height in m

since you did not give the value of h, i cannot fully answer your quesstion.
PE = (58/1000 kg) (9.81m/s2) h
PE = 0.57h
just substitute the value of h in the equation
