surface wave of water is due to the disturbance of medium particles

this is also known as mechanical waves

In mechanical waves we need a mechanical medium to disturb the medium particles which will produce the disturbance

While electromagnetic waves do not require any medium and it can propagate through vacuum

Electromagnetic waves are propagation of electric and magnetic field which is due to oscillation of charge.

So electromagnetic field requires to and from motion of charge particle in which time dependent electric field will induce magnetic field and then they induce each other and propagate in the medium

a car accelerates uniformly at from rest at a speed of 23.7 km/h in 6.5s. find the distance the car travels during this time
hodyreva [135]

speed = distance / time

 distance =speed × time

   d   = v × t

 d=   23.7 kmh⁻¹ ˣ 6.5 s

 d = 154.05 kmh⁻¹s.

A 1100 kgkg safe is 2.4 mm above a heavy-duty spring when the rope holding the safe breaks. The safe hits the spring and compres
Drupady [299]

Answer:

191.36 N/m

Explanation:

From the question,

The Potential Energy of the safe = Energy of the spring when it was compressed.

mgh = 1/2ke²............... Equation 1

Where m = mass of the safe, g = acceleration due to gravity, h = height of the save above the heavy duty spring , k = spring constant, e = compression

Making k the subject of the equation,

k =2mgh/e²................ Equation 2

Given: m = 1100 kg, h = 2.4 mm = 0.0024 m, e = 0.52 m

Constant: g = 9.8 m/s²

Substitute into equation 2

k = 2(1100)(9.8)(0.0024)/0.52²

k = 51.744/0.2704

k = 191.36 N/m

Hence the spring constant of the heavy-duty spring = 191.36 N/m
