When you hear a "pure tone" ... like the sound of a tuning fork
or an audio oscillator ... the pitch you perceive tracks directly
with the frequency.
The 128 Hz tuning fork will sound lower than the 512 Hz one.
In fact, it will sound exactly two octaves lower.
Answer:
tan is 15 for that triangle
Answer:
given function is
formula for newton's method is
so derivative of function is
now put values and solve
or you can also use MATLAB code to solve
i.e
function p= newton(x)
e=0.001;
for i=1:100
if abs(d(x))>e
if abs(k(x))>0
xm=x-(k(x)/d(x));
x=xm;
else
end
break;
end
end
disp(x)
disp(k(x))
return;
Answer:
Explanation:
If friction is neglected, the wheel cannot roll and can only slide frictionlessly and will have the same velocity at the bottom of the ramp as if it had been in free fall as it has converted the same amount of potential energy.
mgh = ½mv²
v = √(2gh) = √(2(9.81)(2.00)) = 6.26418... = 6.26 m/s
However if we do not ignore all friction and the wheel rolls without slipping down the slope, the potential energy becomes linear and rotational kinetic energy
mgh = ½mv² + ½Iω²
mgh = ½mv² + ½(½mR²)(v/R)²
2gh = v² + ½v²
2gh = 3v²/2
v = √(4gh/3) =√(4(9.81)(2.00)/3) = 5.11468... = 5.11 m/s
Answer:
The fastest thing in the whole universe is the speed of light in a vacuum (like outer space!), clocking in at a great 2.99 x 108 m/s. Light travels in waves, and we call this traveling propagation. Propagation of waves has both a speed and a direction, called the velocity. The velocity of light changes depends on the material it travels through.
