Answer:
5.160384 kg*m²/s
Explanation:
The vector angular momentum P can be found using the following expression:
P = I * w
I refers to the inertia, that for a sphere is found using the expression:
I = 
* m * r² = * 15.5kg * (0.510m)² = 1.61262 kg*m².
The angular velocity w is given by the problem, and has a value of 3.2 rad/s.
Replacing the data we get:
P = 1.61262 kg*m² * 3.2 rad/s = 5.160384 kg*m²/s
Answer:
2.4s
Explanation:
The length of the pendulum = 75ft
Diameter d = 12 inches
The time period of the pendulum is given as
T = 2pi(L/g)^1/2
Then the time it takes to move from displacement to equilibrium is given as:
t = T/4
= (Pi/2)*(L/g)^1/2
= pi/2 x [(75x0.3048)/9.81]^0.5
= 1.57x[22.86/9.81)^0.5
= 2.4s
2.4 seconds is the least amount of time that it would take.
Answer:
Since ecosystems contain many different species of animals, plants, and other organisms, consumers have a variety of food sources. The pattern of feeding represented by these interconnected and branching food chains is called a food web. Figure 36-3 shows how food chains within a food web are interconnected.
