A manometer containing oil (rho = 850 kg/m3) is attached to a tank filled with air. If the oil-level difference between the two

columns is 110 cm and the atmospheric pressure is 98 kPa, determine the absolute pressure of the air in the tank.

Answer:

P_{abs}=107172.35Pa\\  P_{abs}=107.172kPa

Explanation:

Given data

P_{a}=98kPa\\ p_{oil}=850kg/m^{3}\\  h=110cm=1.10m

To find absolute pressure of air in the tank.We must find the pressure athe parallel point from the right tube

So

P_{abs}=P_{a}+hp_{oil}g\\P_{abs}=98000Pa+(1.10m*850kg/m^{3}*9.81 )\\P_{abs}=107172.35Pa\\  P_{abs}=107.172kPa

The following four waves are sent along strings with the same
likoan [24]

Answer:

Explanation:

y_1 = (3 mm) sin(x - 3t)

comparing it with standard wave equation

y = A sin( ωt-kx )

we see  

ω = -3 , k = -1

velocity = ω / k

= 3

y_2 = (6 mm) sin(2x - t)

we see  

ω = -1 , k = -2

velocity = ω / k

= .5

y_3 = (1 mm) sin(4x - t)

we see  

ω = -1 , k = -4

velocity = ω / k

= .25

y_4 = (2 mm) sin(x - 2t)

we see  

ω = -2 , k = -1

velocity = ω / k

= 2

So greatest velocity to lowest velocity

y_1 = (3 mm) sin(x - 3t) ,  y_4 = (2 mm) sin(x - 2t) ,y_2 = (6 mm) sin(2x - t) ,  y_3 = (1 mm) sin(4x - t)

b )

Given the mass per unit length of wire the same , velocity is proportional to

√ T , where T is tension

so in respect of tension in the wire same order will exist for highest to lowest tension .

a ball is dopped and falls with an accelerationof 9.8 m/s downward it hits the ground with a velocity of 49 m/s downward how lon
juin [17]

In order to know how long it has been falling for you take the final velocity "49m/s" and divide it by the acceleration "9.8m/s" and get 5, since you have been using seconds in the calculations the answer is 5 seconds. (Fun fact, it is actually 9.82m/s per second since it accelerates and they rounded it down.)
