Sergeu [11.5K]

Answer:

Option B. 6.25 J/S

Explanation:

Data obtained from the question include:

t (time) = 2secs

F (force) = 50N

d (distance) = 0.25m

P (power) =?

The power can be obtained by using the formula P = workdone/time.

P = workdone / time

P = (50 x 0.25)/ 2

P = 6.25J/s

aleksklad [387]

Answer:

 To=20.44 °C    

Explanation:

Given that

Velocity , v= 30 m/s

Temperature , T= 20°C

We know that specific heat capacity for air ,Cp=1.005 kJ/kg.K

By using energy conservation ,the stagnation temperature is given as

T_0=T+\dfrac{v^2}{2C_p}

Now by putting the values in the above equation we get

T_0=(20+273)+\dfrac{30^2}{2\times 1.005\times 1000}\ K

To= 293.44 K

To= 293.44 - 273 °C

To=20.44 °C

Therefore the stagnation temperature will be 20.44 °C.

How much must a man weigh (force) if the pressure he exerts while standing on one foot which has an area of 25 m^2 exerts a pres
andriy [413]

Answer:

Weight, W = 125 N

Explanation:

Pressure, P = 5 Pa

Area, A = 25 m²

We need to find how much must a man weigh (force) if the pressure he exerts while standing on one foot which has an area of 25 m² exerts a pressure of 5 Pa. So,

Pressure = force/area

So,

F=P\times A\\\\F=5\times 25\\F=125\ N

So, the weight of the man is 125 N.
