To solve this problem, we can use the cosine formula for
calculating the length of the displacement:
c^2 = a^2 + b^2 – 2 a b cos θ
where c is the displacement, a = 3.5 km, b = 4.5 km, and θ
is the angle inside the triangle
Since the geeze turned 40° from west to north, so the
angle inside the triangle must be:
θ = 180 – 40 = 140°
c^2 = 3.5^2 + 4.5^2 – 2 (3.5) (4.5) cos 140
c^2 = 56.63
c = 7.53 km
<span>So the magnitude of the displacement is 7.53 km</span>
60.9 - 4.9= 56
56 is the net force
using the formula F = ma
56= 8a
a = 7
acceleration is 7ms^-2
1. The seamount of the following given option is option D, i.e. Loihi.
2. Hawaii would be the location for the most active volcano according to the picture given.
Answer: Option D and Option B
<u>Explanation:</u>
1. Loihi is a seamount, which is a uplifted mountain risen to a certain altitude from the oceanic floor, but has no connection with the sea floor and hence do not come into the purview of being an island. sea mount are thus known as the submarine peak.
2. According to the diagram given, active site for volcano is Hawaii. the reason being that the hot spot for the volcanic activity is found beneath the Hawaiin island, whose tremendous stress is experienced below the fault line of Hawaii making it the most active site for volcano as per the seismological findings.
