We now slowly increase the pressure to 15464.04 Pa while keeping the temperature constant. What is the final volume?

Mila [183]

Answer:

Final volume = 0.42 cubic meters

Explanation:

The question is incomplete. The initial conditions are

Initial temperature , $T_{1}$ = 310 K

Initial volume , $V_{1}$ = 0.5 cubic meter

Number of moles = 2.5

Since, from the ideal gas equation we get,

PV = nRT

P $\times 0.5 = 2.5 \times 8.314 \times 310$

$P_{1}$ = 12886.7 Pa

Final pressure= 15464.04 Pa

Since temperature is constant,

PV = constant

$12886.7 \times 0.5 = 15464.04 \times V$

V = 0.42 cubic meters.

Hence final volume = 0.42 cubic meters

If a hammer has a resistance arm of 3 inches and the effort arm is 15 inches. What is the mechanical advantage?

Sunny_sXe [5.5K]

Answer:

Option D

MA=5

Explanation:

Mechanical advantage is the the ratio of the output force to the input force hence

$MA=\frac {Effort arm length}{Load arm length}$

Substituting 15 inches for the effort arm length and 3 inches for the load arm length then we obtain the mechanical advantage as

$MA=\frac {15}{3}=5$
