Calculate the minimum average power output necessary for a person to run up a 12.0 m long hillside, which is inclined at 25.0° a
Viktor [21]

Answer:

Power, P = 924.15 watts

Explanation:

Given that,

Length of the ramp, l = 12 m

Mass of the person, m = 55.8 kg

Angle between the inclined plane and the horizontal, \theta=25^{\circ}

Time, t = 3 s

Let h is the height of the hill from the horizontal,

h=l\ sin\theta

h=12\times \ sin(25)

h = 5.07 m

Let P is the power output necessary for a person to run up long hill side as :

P=\dfrac{E}{t}

P=\dfrac{mgh}{t}

P=\dfrac{55.8\times 9.8\times 5.07}{3}

P = 924.15 watts

So, the minimum average power output necessary for a person to run up is 924.15 watts. Hence, this is the required solution.

Under what conditions can an ideal gas undergo a change of state without doing external work?
Cerrena [4.2K]
Nswer 

<span>Work done = Pressure * ΔV [ change in volume ] </span>

<span>If ΔV=0, then no work is done </span>

<span>Zero work thermodyanamic process is called ' isochoric process.' </span>

<span>For example if a gas heated in a rigid container: the pressure and temperature </span>
<span>of the gas will increase, but the volume will remain the same. </span>

<span>This is called an isochoric thermodynamic process. </span>

<span>It is actually possible to do work on a system without changing the </span>
