Answer: Force and Movement
Explanation:
The first is that the object moves. The second is that a force must act on the object in the direction the object moves.
Answer:
Magnitude of y-component=7 units
Direction= angle of vector A with x-axis=

Answer:
Explanation:
The distance traveled by the sound wave between the beats of the wing is its wavelength, since it is defined as the distance traveled by a periodic disturbance that propagates in a cycle, is defined as:
Where v is the speed of sound and f the frequency of the wing beats

Answer:
Explanation:
- The concept of gibb's free energy is applied in the problem. Mathematically from Gibb's free energy ; ΔG = ΔH - TΔS
- Entropy = ΔS = is the degree of disorderliness of the system.
- Since the enthalpy of vaporization is given ΔHvap = 38.0kJ/mol = 38000J/mol
- Also ΔSvap = 112.9J/mol.K
- Temperature of the experiment given = 75 degree celsius
calculate the boiling point of the solvent ; T = ΔHvap/ΔSvap
- T = 38000J/mol / 112.9J/mol.K
- = 335.57K , in celsius ; 335.57K - 273
the temperature calculated indicates that the solvent is not suitable for the experiment because its boiling point is lesser than the temperature at which the experiment want to be carried out.
