What is sound wave?</h3>
A sound wave is the pattern of disruption brought on by the movement of energy moving through a medium as it propagates away from the source of the sound (such as air, water, or any other liquid or solid substance). Pressure waves are produced when an item vibrates, such as a ringing phone, and these waves are known as sound waves. The surrounding medium's particles are disturbed by the pressure wave, and those particles disrupt the particles next to them, and so on. Like ocean waves, the disturbance's pattern causes outward movement in all directions. Usually in all directions and with decreased intensity as it gets further away from the source, the wave transmits the sound energy through the medium.

Answer:
W = 7.53 inches
H = 30.14 inches
Explanation:
Printing area is:
Solving for :
The total area of the paper is:
Replacing :
If we derivate and equal zero to find the minimum:
So,
The final dimensions of the paper are:
W = 3.53 + 4=7.53-inch
H = 14.14 + 16= 30.14-inch
Answer:
Delta pressure = 45938[Pa]
Explanation:
This is a classic bernoulli equation problem, but first we must find the velocity at both ends of the pipe, knowing the diameters of each end.
Now we can calculate the two velocites VA and VB
Using the bernoulli equation we have:
Where ro = density of water = 1000[kg/m^3]
Answer:
the bell has potential energy equal to,
18 x 9.8 x 45 = 7938 joules
Answer:
a) 4.8×10^-5T
b) 7.38×10^-7seconds
Explanation:
The centripetal force in a magnetic field is given by:
qvB= mv2/r
Where q= charge of the ion
m= mass of the ion
r= radius of the circular path
B= magnetic field
V= velocity
Rearranging to make B subject of formular gives:
B=mv/r
B= [(9.11×10^-31)×(5.87×10^5)]/ [(1.6×10^-19)×(6.81×10^-2)]
B = (5 34×10^-25)/(1.099×10^-20)
B= 4.86×10^-5T
b) T =( 2 pi × r)/v
T = 2 × 3.142 x (6.81×10^-2) / (5.87×10^5
T = 0.428/ (5.87×10^5)
T = 7.38 × 10^-7seconds
