Answer:
(Left Force absolute value) Fl=29500N
Explanation:
When considering the bridge in a static state, it is essential to acknowledge its equilibrium. At this point, torques can be utilized to solve for the answer, as illustrated below:
If assessing the torque around the right pier, the distance Fl measures 40 m, the weight of the car (Wa) is located 12 m from it, and the bridge's center of mass (Wb) is 20 m from that point, while the Right Force pier sits at 0m, where it effectively has no contribution to rotation.
The signs signify the direction of torque, whether positive or negative, based on the chosen reference point (in this scenario, the torque point is set at the right pier).
Ultimately, substituting in the values provides the Left Force result:
Answer:
Explanation:
The overall energy expenditure of the salmon, which corresponds to its swimming upstream effort, , is linked to its specific mechanical power.
calculated per unit mass can be derived from the following equation:
As a result, the total energy utilized during the 22-day journey is 7.603 MJ
Response:
U = 12,205.5 J
Clarification:
To determine the internal energy of an ideal gas, use the following equation:
(1)
U: internal energy
R: ideal gas constant = 8.135 J(mol.K)
n: number of moles = 10 mol
T: the temperature of the gas = 100K
Substituting the parameter values into equation (1):
The overall internal energy for 10 moles of Oxygen at 100K is 12,205.5 J
