Answer:
t = 3.94 s
Explanation:
This can be modeled as a case of free fall motion. Because, the falcon is going down with acceleration, that is equal to acceleration due to gravity. To find the time taken by the falcon to intercept the pigeon, we will use second equation of motion for vertical direction:
where,
h = height = 76 m
vi = initial speed of falcon = 0 m/s
t = time required = ?
g = acceleration due to gravity = 9.81 m/s²
Therefore,
<u>t = 3.94 s</u>
Answer:
1.2 m from the left end
Explanation:
= mass of the person = 90 kg
= mass of friend = 60 kg
= distance of pivot from the person or from the left end
= length of the seesaw board = 3.0 m
= distance of pivot from the friend or from right end = L - r = 3 - r
Using equilibrium of torque about the pivot
The characteristics of electromagnetic waves typically represent as follows:
- There are changes in the electric and magnetic fields simultaneously so that both fields have maximum and minimum values at the same time and place.
- The direction of the electric field and the magnetic field are perpendicular to each other. The direction of both is perpendicular to the direction of the wave propagation.
- The shape of electromagnetic waves is transverse waves.
- It has general wave characteristics like polarization, reflection, refraction, interference, and diffraction.
- The amount of the electric field (E) is directly proportional to the magnitude of the magnetic field, with the relationship E = cB.
- The universal constant of the velocity of electromagnetic waves in a vacuum is
- The speed at which electromagnetic waves propagate depends merely on the electrical and magnetic properties of the medium that it travels on.
- Because electromagnetic waves do not contain an electric charge, they do not experience any possible deviation in the electric or magnetic fields.
- Two physicists who contributed significantly to developing the concept of electromagnetic waves are Faraday and Maxwell around 1831-1864.
- From the observations, Faraday suggested that changes in the magnetic field cause an electric charge to flow in the loop of wire, contributing in the emergence of an electric field.
- Maxwell proposed a reverse process, which is a change in the electric field will generate a magnetic field.
- As follows, according to Faraday's Law, changes in sinusoidal magnetic fields generate electric fields which also change sinusoidally.
- Meantime, according to Maxwell's Hypothesis, changes in sinusoidal electric fields generate magnetic fields which also change sinusoidally.
- Furthermore, there is a process of combining electric and magnetic fields that propagate in all directions called electromagnetic waves.
