<h3><u>Answer;</u></h3>
Energy
<h3><u>Explanation;</u></h3>
- A wave is a transmission of disturbance from one point to another. All waves involve transmission of energy from one point called the source to another point.
- <em><u>Waves describes various ways in which energy can be transferred from a point source.</u></em>
- <em><u>In electromagnetic waves</u></em><em>, for instance, </em><em><u>energy transmission occurs as a result of vibrations of electric and magnetic fields</u></em><u>.</u>
- <u><em>In mechanical waves energy transmission is as a result of vibration of particles in the medium used</em></u>. For example in sound waves, energy is transferred through vibration of particles of air or particles of a solid or medium through which sound travels through.
Answer:
Hans-Georg Gadamer (1900-2002) was an influential German philosopher of the twentieth century, inspiring a variety of scholastic disciplines from aesthetics to theology. In suggesting understanding was interpretation and vice versa, Gadamer identifies language acting as the medium for understanding. Gadamer’s philosophy of hermeneutics has major implications for education and formal schooling because Hermeneutics help to know the knowledge a student has prior to the lesson. This helps in the dialogue about a subject matter and therefore, the philosophy of Hermeneutics when applied in classroom helps the teachers pass information easily and effectively, hence, the learners capture the whole content of a topic.
Explanation:
Kinetic Energy is movement energy (most simplistic way I can put it) so its motion.
Answer:
Solution:
we have given the equation of motion is x(t)=8sint [where t in seconds and x in centimeter]
Position, velocity and acceleration are all based on the equation of motion.
The equation represents the position. The first derivative gives the velocity and the 2nd derivative gives the acceleration.
x(t)=8sint
x'(t)=8cost
x"(t)=-8sint
now at time t=2pi/3,
position, x(t)=8sin(2pi/3)=4*squart(3)cm.
velocity, x'(t)=8cos(2pi/3)==4cm/s
acceleration, x"(t)==8sin(2pi/3)=-4cm/s^2
so at present the direction is in y-axis.
