B = magnetic field in the cyclotron = 0.400 T
q = magnitude of charge on a proton = 1.6 x 10⁻¹⁹ C
m = mass of the proton = 1.67 x 10⁻²⁷ kg
f = frequency of revolution of proton in the cyclotron = ?
v = speed of electromagnetic waves = 3 x 10⁸ m/s
λ = wavelength of electromagnetic wave = ?
Frequency of revolution of proton in the cyclotron is given as
f = qB/(2πm)
inserting the values
f = (1.6 x 10⁻¹⁹)(0.400)/(2 (3.14) (1.67 x 10⁻²⁷))
f = 6.1 x 10⁶ Hz
wavelength of electromagnetic wave is given as
λ = v/f
λ = (3 x 10⁸)/(6.1 x 10⁶)
λ = 49.2 m
Answer:
A. 500 N
Explanation:
Acceleration is change in velocity over change in time.
a = Δv / Δt
a = (50 m/s − 20 m/s) / 3 s
a = 10 m/s²
Force is mass times acceleration.
F = ma
F = (50 kg) (10 m/s²)
F = 500 N
Answer:
if it were to be digital then you would be able to carry it around where ever and look at it to remind you of the memories, however it probably wouldnt last as long as the physical one. eg if you phone breaks there is a chance to restore the photo but you would had to have backed it up beforehand.
Answer:
I don't think any options are correct.
Explanation:
When solved for y the process goes as follows:
5x+ 8y = 16
5x + 8y - 5x = 16 - 5x
8y = 16 - 5x
8y/8 = (16-5x)/8
y = 2- (5/8)x
Answer:
Metal - smallest band gap energy
insulators - large band gap energies
semiconductor - Band gap of intermediate energies
superconductor cooper pair theory is applied for calculating gap energies.
Explanation:
Metal - smallest band gap energy
it is due to the fact that valence and conduction bond in metal are in overlapped conditioned. Therefore showing zero gap energies
insulators - large band gap energies
insulator has high band gap
semiconductor - Band gap of intermediate energies
semi conductor has gap of intermediate range
while for superconductor cooper pair theory is applied for calculating gap energies.
