Answer:
x = 600 Km
Explanation:
given,
speed of transverse wave = 4.05 Km/s
speed of longitudinal wave = 7.695 Km/s
difference of the time of arrival of wave = 69.9 s
now,
t₂ - t₁ = 69.9 s
let x be the distance
x = 597.645 Km
x = 600 Km
distance of recorder from the site is 600 Km approximately.
Using Kepler's 3rd law which is: T² = 4π²r³ / GM
Solved for r :
r = [GMT² / 4π²]⅓
Where G is the universal gravitational constant,M is the mass of the sun,T is the asteroid's period in seconds, andr is the radius of the orbit.
Change 5.00 years to seconds :
5.00years = 5.00years(365days/year)(24.0hours/day)(6... = 1.58 x 10^8s
The radius of the orbit then is computed:
r = [(6.67 x 10^-11N∙m²/kg²)(1.99 x 10^30kg)(1.58 x 10^8s)² / 4π²]⅓ = 4.38 x 10^11m
Answer:
frictonal force due to the surface of irregularities
Answer:
Copper isn't ferromagnetic,
Aluminum isn't ferromagnetic,
String has a ferromagnetic property
So in conclusion:
The answer is strings :)
