4. What is the density of a substance that weighs 45 g and is 70 mL?<br> (Density = g/mL)

AysviL [449]

Answer:

<h2>0.64 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

$d = \frac{m}{v} \\$

m is the mass

v is the volume

From the question

m = 45 g

v = 70 mL

We have

$d = \frac{45}{70} = \frac{9}{14} \\ = 0.6428571...$

We have the final answer as

<h3>0.64 g/mL</h3>

Hope this helps you

A 24-cm-diameter vertical cylinder is sealed at the top by a frictionless 15 kg piston. The piston is 90 cm above the bottom whe

abruzzese [7]

Answer:

(A) $P_i=3249.41\ Pa$

(B) $V_f=0.3358\ m$

Explanation:

Given:

diameter of the cylinder, $d= 0.24\ m$

mass of piston sealing on the top, $m_p=15\ kg$

initial temperature of the piston, $T_i=315+273= 588\ K$

initial height of piston, $h_i=0.9\ m$

atmospheric pressure on the piston, $p_a=1 atm=101325\ Pa$

(A)

<u>Initial pressure of gas is the pressure balanced by the weight of piston:</u>

$P_i=\frac{m_p.g}{\pi.d^2\div 4}$

$P_i=\frac{15\times 9.8}{\pi\times (0.24^2\div 4)}$

$P_i=3249.41\ Pa$

<em>Which is gauge pressure because it is measured with respect to the atmospheric pressure.</em>

(B)

Given:

Final temperature, $T_f=18+273=291\ K$

<u>Now, volume of air initially in the cylinder:</u>

$V_i=\pi.d.h_i$

$V_i=\pi\times 0.24\times 0.9$

$V_i=0.6786\ m^3$

Using gas law:

$\frac{P_i V_i}{T_i}= \frac{P_f V_f}{T_f}$ ........................................(1)

<em>∵In every condition of equilibrium the gas pressure will be balanced by the weight of the piston so it is an </em><em>isobaric transition</em><em>.</em>

∴ $P_i=P_f$

<u>Hence eq. (1) is reduced to:</u>

$\frac{V_i}{T_i}= \frac{V_f}{T_f}$

putting respective values:

$\frac{0.6786}{588}= \frac{V_f}{291}$

$V_f=0.3358\ m$

A force of 333 N is applied 33 cm from the pivot point. What is the maximum torque of this situation

exis [7]

Answer: 109.89 Nm

Explanation:

The maximum torque will be calculated as the force multiplied by the perpendicular distance. This will be:

Torque = force × perpendicular distance

torque = 333 × 0.33

= 109.89 Nm
