Answer:
90°
Explanation:
This angle is the measured between the force applied and the displacement where the force vector and the displacement vector are on opposite direction.
The formula for work in this case is ;
W=F*d* cos ∅ where ;
F= force, d= distance and ∅ is the work angle
For minimum work ∅ = 90°
For maximum work ∅ = 0°
The correct answer for the question that is being presented above is this one: "D. smaller than." In a practical machine, the power output is smaller than the power input. The power output is smaller than the power input as most of the energy usually has been converted to heat in the process.
Transverse Waves: Displacement of the medium is perpendicular to the direction of propagation of the wave.
Longitudinal Waves: Displacement of the medium is parallel to the direction of propagation of the wave.
Answer:
B. symbolic
Explanation:
The mental image formed in Terell's mind is a symbolic mental image.
A symbolic mental image helps to bring perception to imagery formed on the mind.
- This process is symbolic because Terell can see that river ahead.
- If he cannot see the river then it is more of an analogical fantasy.
- The thoughts are predicated on the image of the River seen.
- Therefore, it is right to conclude that this is a symbolic mental image.
