Answer:
<em>2.72 x 10^-43 m</em>
<em></em>
Explanation:
mass of the telescope = 7500 kg
speed of the telescope = 3.25 x 10^5 m/s
de Broglie's wavelength of the telescope is given as
λ = h/mv
where
λ is the wavelength of the telescope
h is the plank's constant = 6.63 × 10-34 m^2 kg/s
m is the mass of the telescope = 7500 kg
v is speed of the telescope = 3.25 x 10^5 m/s
substituting value, we have
λ = (6.63 × 10-34)/(7500 x 3.25 x 10^5)
λ = <em>2.72 x 10^-43 m</em>
Answer:
Every rock is somewhere in the rock cycle. The story of the rock is the story of rock cycle: where the rock is now on the rock cycle, the path it took on the rock cycle to get to where it is now, and the path on the rock
Explanation:
This is the answer i put it and it worked if it didn't work for you that's because you lesson or teacher was doing it in a different way.
Answer:
D
Explanation:
The CV system does all of the above
Answer:
1.8m/s
Explanation:
We know that the momentum of an impact of a body is the mass times he velocity
M= mv
Given data
Mass m= 10kg
Momentum M= 18 kg.m/s
Velocity v=?
We can solve for velocity by submitting our given data in the momentum equation
18 = 10*v
v= 18/10
v= 1.8m/s
Answer:
frequency = 104.80 Hz
wavelength = 0.567 m
frequency = 104.80 Hz
wavelength = 3.27 m
Explanation:
given data
mass m = 9.4 g = 9.4 × m
length L = 85 cm = 0.85 m
tension T = 39 N
to find out
frequency and wavelength
solution
first we find frequency for second overtone
f = 3 /2L × √(T/μ) .............1
put here all value and
here μ = m/L = 9.4 × / 0.85 = 1.10588 × kg/m
f = 3 /2(0.85) × √(39/1.10588 ×)
f = 104.80 Hz
and
wavelength is 2L/3
wavelength = 2(0.85) / 3
wavelength = 0.567 m
and
frequency = 104.80 Hz
and
wavelength by speed of sound i.e 343 m/s
wavelength = speed / f
wavelength = 343 / 104.80
wavelength = 3.27 m
