i don't know but i will give you 25 points (MrBeast)
Answer:
Explanation:
As we know that magnetic field due to torroid is given as
this is approximately constant magnetic field along the axis of the torroid
now the flux linked with one coil of the torroid is given as
now total flux of N number of coils is given as
now we know that self inductance is the property of coil in which flux of the coil will link with the current in the coil
So we know that
Answer:
a) Wavelength of the ultrasound wave = 0.0143 m <<< 3.5m, hence its ability is not limited by the ultrasound's wavelength.
b) Minimum time difference between the oscillations = Period of oscillation = 0.00952 ms
Explanation:
The frequency of the ultrasound wave = 105 KHz = 105000 Hz. The speed of ultrasound waves in water ≈ 1500 m/s. Wavelength = ?
v = fλ
λ = v/f = 1500/105000 = 0.0143 m <<< 3.5m
This value, 0.0143m is way less than the 3.5m presented in the question, hence, this ability is not limited by the ultrasound's wavelength.
b) Minimum time difference between the oscillations = The period of oscillation = 1/f = 1/105000 = 0.00000952s = 0.00952 ms
Hope this helps!
Answer:
depends the ancient humans or the start of the solar system
Explanation:
if its the humans the earth was in the middle of everything.
but the beginning of the solar system lets say when earth just formed the orbits where unstable and planet ending impacts happed a lot.
ill do the proto planetary disc too
the disc formed the gas giants first then the rockey planets formed out of the disc
