A glass capillary is placed in a bowl of water. Into what type of capillary will the water rise to the highest level?

Answer:

a 1-mm wide capillary inserted vertically into the water

Explanation:

When you introduce the capillary tube upright in the liquid and observe how the height of liquid in the capillary increases as time goes by.

When the liquid of viscosity h, ascends through the capillary tube of radius r, we will assume that it flows in a laminar regime, we apply the Poiseuille law.

When the pressure difference becomes zero, Dp = 0, the equilibrium situation studied in the previous section is reached. The liquid stops ascending through the capillary tube. The height at which the liquid rises is maximum when the capillary is 1 mm thick and is introduced vertically into the water

A jet leaves a runway whose bearing is N 3232degrees°E from the control tower. After flying 77 ​miles, the jet turns 90degrees°
OverLord2011 [107]

Answer:

N(80.8^{\circ})E

Explanation:

Bearing from control tower= N(32^{\circ}+\theta})E

But tan \theta=\frac {opposite}{adjacent}

tan \theta=\frac {88}{77}

\theta=tan^{-1}(\frac {88}{77})=tan^{-1}(1.142857143)=48.81407483^{\circ}\approx 48.8^{\circ}

Therefore, the bearing from control tower=N(32^{\circ}+48.8^{\circ}})E

Bearing=N(80.8^{\circ})E

The direction is North East

1.An 8-kilogram bowling ball is rolling in a straight line toward you. If its momentum is 16 kg•m/s, how fast is it traveling?

1. An 8-kilogram bowling ball is rolling in a straight line toward you. If its momentum is 16 kg•m/s, how fast is it traveling?
 
momentum = mass x velocity
16 = 8 x velocity
velocity = 2 m/s

2.A beach ball is rolling in a straight line toward you at a speed of 0.5 m/sec. Its momentum is 0.25 kg•m/s. What is the mass of the beach ball?

momentum = mass x velocity
0.25 = m x 0.5
mass = 0.5 kg

3.A 4,000-kilogram truck travels in a straight line at 10.0 m/s. What is its momentum?
Momentum = (mass) x (speed) = (4,000) x (10) = 40,000 kilogram-meters/second

4.A 1,400-kilogram car is also traveling in a straight line. Its momentum is equal to that of the truck in the previous question. What is the velocity of the car?

40,000 kilogram-meters/second = 1400 x velocity
velocity = 28.6 m/s

5.Which would take more force to stop in 10 seconds: an 8.0-kilogram ball rolling in a straight line at a speed of 0.2 m/s or a 4.0-kilogram ball rolling along the same path at a speed of 1.0 m/s?

F1 = 8 x  0.2 / 10 = 0.16 N
F2 = 4 x 1.0 / 10 = 0.4 N ----> take more force

6.The momentum of a car traveling in a straight line at 20 m/s is 24,500 kg•m/s. What is the car’s mass?

24500 = mass x 20
mass = 1225 kg

7.Another pitcher throws the same baseball in a straight line. Its momentum is 2.1 kg•m/s. What is the velocity of the ball?

2.1 = 0.5 x velocity
velocity = 4.2 m/s

8 A 1-kilogram turtle crawls in a straight line at a speed of 0.01 m/s. What is the turtle’s momentum?

momentum = 1 x 0.01 = 0.01 kg m/s
