It’s true there are sections in the periodic table that define the elements.
<span>A body wave is a seismic wave that moves through the interior of the earth, as opposed to surface waves that travel near the earth's surface.
P and S waves are body waves. Each type of wave shakes the ground in different ways</span>
Answer:
Explanation:
Given data
Flight distance S=4890 km
Time difference Δt=t₂-t₁=40 min
Air speed of plane=980 km/h
To find
Speed of jet stream
Solution
When moving in the same direction as the jet stream time taken as t₁=d/(v+vs),v is velocity of plane and vs is velocity of plane
While moving in opposite direction t₂=d/(v+vs)
So
Apply quadratic formula to solve for vs
So
Cannot be determined, I need more information.
