Answer: C

Gauge pressure = 156 kPa ,

What is absolute pressure =?

     We know that,

      absolute pressure = gauge pressure + atmospheric pressure

                           Pabs = Pgauge + Patm

                                     = 156 + 101.3          <em>  </em><em> (since atm.pr. = 101.3 Kpa)</em>

<em>                                      </em><em>= 257.3 KPa absoulte</em>

<em>                                      approximately  = 256 KPa absolue</em>

lesya [120]

Answer:

W = 270.9 J

Explanation:

given,  

F(x) = (12.9 N/m²) x²  

work = Force x displacement  

dW = F  .dx  

the push-rod moves from x₁= 1 m to x₂ = 4 m

integrating the above  

\int dW = \int_{x_1}^{x_2}F. dx

W = \int_{x_1}^{x_2}F. dx

W = \int_{1}^{4} (12.9 x^2) dx

W = 12.9\times [\dfrac{x^3}{3}]_1^4 dx

`W = 12.9\times [\dfrac{4^3}{3}-\dfrac{1^3}{3}] dx

W = 270.9 J

work done by the motor is W = 270.9 J

A hiker begins a trip by first walking 25.0 km southeast from her car. She stops and sets up her tent for the night. On the seco
Sunny_sXe [5.5K]

Answer:

(a)

x_1=17.68km\\y_1=-17.68km\\x_2=20km\\y_2=34.64km

(b) r=41.32km

\alpha =24.23^o

Explanation:

Let us take the north direction to be the positive y-axis and the east to be positive x-axis.

First day:

25.0 km southeast, which implies 45^o south of east. The y-component will be negative and the x-component will be positive.

x_1=25cos45^o=17.68km

y_1=-25sin45^o=-17.68km

Second day:

She starts off at the stopping point of last day. This time, both the y- and x-components are positive.

x_2=40cos60^o=20km

y_2=40sin60^o=34.64km

Therefore, total displacements:

x=x_1+x_2=(17.68+20)km=37.68km

y=y_1+y_2=(-17.68+34.64)km=16.96km

Magnitude of displacements,

r=\sqrt{x^2+y^2}=41.32km

Direction,

\alpha =tan^{-1}(\frac{y}{x})=24.23^o

san4es73 [151]

Answer:

6 seconds

0.167 Hz

Explanation:

Distance = 4 m

Velocity = 0.75 m/s

Period is given by

T=2\times Distance\times Velocity\\\Rightarrow T=2\times 4\times 0.75\\\Rightarrow T=6\ s

The period of the motion is 3 seconds

Frequency is given by

f=\frac{1}{T}\\\Rightarrow f=\frac{1}{6}\\\Rightarrow f=0.167\ Hz

The frequency of the motion is 0.33 Hz
