Answer:
the force happens on the wall and couch
Explanation:
she is using her arm strength to lift and hold
D It is released or absorbed.
Explanation:
To form a solution, energy is absorbed or released in the process.
A solution is a substance made up of solute dissolved in a solvent. The solute is the dissolved substance where as the solvent is the dissolving medium.
- To form a solution, solutes are dissolved.
- In this dissolution reaction, energy is used to break bonds within the solute to bring them in contact with the solvent.
- The combination of the solute with the solvent is a bond formation process.
- Bond formation is an exothermic process in which energy is released.
- Bond breaking process is endothermic in which energy is absorbed.
- To form solutions, bonds are formed and broken.

Answer:
Answer for the question :
"Consider a rectangular wing mounted in a low-speed subsonic wind tunnel. The wing model completely spans the test-section, so that the flow "sees" essentially an infinite wing. The wing has a NACA 23012 airfoil section and a chord of 0.23 m, where the lift on the entire wing is measured as 200 N by the wind tunnel force balance. Determine the angle of attack if the wing span, airflow pressure, temperature, and velocity are 2 m, 1 atm, 303 K, and 42 m/s, respectively. Refer to the Appendix graphs given below for standard values" is in the attachment.
