Answer:
<em>The speed of the stream of air flowing through the leak is 340.754 m/sec</em>
Explanation:
Carefully applying the Bernoulli's equation the speed of the leak can be obtained. The attached images show step by step explanation of the question, while applying the Bernoulli's equation;
whats the example? That all yu should look it up on internet.
1. orbit (the missing one)
2. axis
a. summer, northern
b. winter, northern
4. equinox
Answer:
2.21 N
Explanation:
The force in this case is the total mass multiplied by the acceleration due to gravity. You are not asked for the solution to be in terms of the torque which is the usual way to solve these problems. That's why you are not given where the fulcrum is.
The fulcrum feels F1 + F2 + 34 * 980
F2 = 141.7 * 980 = 138866
F1 = 50.3 * 980 = 49294
Ruler = 34 * 980= 33320
Total Force = 221480 The units here are dynes
I just saw in the middle of the question that g = 9.80
So the answer becomes 221480 / 1000 = 221.48 because we needed kg
And that answer becomes 221.48/100 2.21 because the force of gravity should be 9.8 not 980
The total force exerted on the fulcrum is
The time of fly of a projectile to the same level as it was launched is 2(v_y)/g=2(47sin(25))/g. We multiply this by the v_x to get the distance. Thus, the distance is <span>2(47sin(25))/g*47cos(25)=86.2. This is a overshoot!</span>
