Answer:
184 Km
Explanation:
given,
speed of S wave = 4.50 Km/s
speed of P wave = 7.80 Km/s
reading time difference = 17.3 s
we know,
distance = speed x time
time taken by s-wave
time taken by the P-wave
now,
t₁ - t₂ = 17.3 s
3.3 x = 607.23
x = 184 Km
distance of the focus from the station is 184 Km.
Answer:
Explanation:
For this problem, we need to make use of Newton's law of universal gravitation. This law states that two objects attract each other with a force that is inversely proportional to the square of the distance of their centers of mass and directly proportional to the product of their masses. We can write this as:
where F is the attractive force, G is the gravitational constant, r is the distance between their centers of mass, and M and m are the masses of the objects.
From here we will let M be the mass of the earth, and m the mass columbia. From Newton's second law, we know that the gravitational force exerted to columbia due to the earth can be written as
,
here, making a substitution we get
The distance between columbia and the earth's center is
.
Now, computing the acceleration:
It would be A: Have a greater height.
The higher the wave the higher the energy!
