Answer:
B. 10m/s
Explanation:
If a drone flies 8 m/s due East with respects to the wind and the wind is blowing 6 m/s due North, the speed of the drone with respect to the ground is its displacement.
Displacement is calculated using Pythagoras theorem.
d² = 8²+6²
d² = 64+36
d² = 100
Square root both sides
√d² = √100
d = 10m/s
Hence the distance of the drone with respect to the ground is 10m/s
Option B is correct
Answer:
hi iam 8 and a girl your hot
Explanation:
To find the relative distance from one point to another it is necessary to apply the Relativity equations.
Under the concept of relativity the distance measured from a spatial object is given by the equation

Where
= Relative length
v = Velocity of the spaceship
c = Speed of light
Replacing with our values we have that




Therefore the distance between Mars and Venus measured by the Martin is

By getting seismic information from multiple seismographs bases off the intensity of the waves and time of impact relative to other seismographs a location can be pinpointed.
