Answer:
The red one
Explanation:
not acturlly a thing between them so i might be wrong
As ice melts into water, kinetic energy is being added to the particles. This causes them to be 'excited' and they break the bonds that hold them together as a solid, resulting in a change of state: solid -> liquid.
Answer:
critical clearing angle = 70.3°
Explanation:
Generator operating at = 50 Hz
power delivered = 1 pu
power transferable when there is a fault = 0.5 pu
power transferable before there is a fault = 2.0 pu
power transferable after fault clearance = 1.5 pu
using equal area criterion to determine the critical clearing angle
Attached is the power angle curve diagram and the remaining part of the solution.
The power angle curve is given as
= Pmax sinβ
therefore : 2sinβo = Pm
2sinβo = 1
sinβo = 0.5 pu
βo =
⁰
also ; 1.5sinβ1 = 1
sinβ1 = 1/1.5
β1 =
= 41.81⁰
∴ βmax = 180 - 41.81 = 138.19⁰
attached is the remaining solution
The critical clearing angle =
≈ 70.3⁰
Answer:
Coaching or mentoring
Coaching or mentoring can share similar qualities to hands-on training, but in this type of employee training, the focus is on the relationship between an employee and a more experienced professional, such as their supervisor, a coach, or a veteran employee.
The one-on-one mentoring style creates a relationship between employees that carries far beyond training. Lecture-style training
Important for getting big chunks of information to a large employee population, lecture-style training can be an invaluable resource for communicating required information quickly.
However, use this type of employee training sparingly.
