Answer:
The answer is 1250 mm
Explanation:
The path that particles move in the spectrometer is semicircular. Each of the particles has a displacement of twice the radius (2r) from the entrance to where the film is hit. According to the exercise, if the separation between the two molecules is 0.25 mm, then the difference in the radius of the molecules is equal to 0.125 mm. The ratio of mass/radius is equal for molecules, and therefore is equal to:
m = q * B * r / v
m/r = constant
(m/r)CO = (m/r)N = (28.0106 u/r) = (28.0134 u/(r + 0.000125 m))
Clearing and solving r:
r = 1.25 m = 1250 mm
Answer:
a.87.6 m/s
b.18.25 Hz
Explanation:
the equation for the wave speed is expressed as
where v is the speed,
T is the tension in Newton
l is the length
and m is the mass
Now since
by substituting values into the equation, we have
b. the expression for the frequency is giving as
.
Note we 2L as the wavelength because we solving for the fundamental frequency as stated in the question.
Answer:
mechanical energy to heat energy to chemical energy
