Answer:
Is always towards the center of the Earth
Explanation:
As a satellite moves around the Earth in a circular orbit, the direction of the force of gravity is always towards the center of the Earth. At an altitude of 100 km, you would be so high that you would see black sky and stars if you looked upwards.
Answer:
.
Explanation:
Sound waves are caused by vibration ripples in water are caused by disturbance in the molecules
Explanation: Velocity is the displacement of an object during a specific unit of time. Two measurements are needed to determine velocity. Displacement and time. Displacement includes a direction, so velocity also includes a direction. Speed with direction. Velocity can be an average velocity or an instantaneous velocity. Units for velocity are the same as for speed: m/s, km/h, and mph. Delta x(Δx) is the symbol used for displacement. Delta (Δ) means to "change in." Δx means to "change in position." Δx is calculated by final position minus initial position. Velocity formula: → v=Δx/t as a fraction.
v=Δx/t

<em><u>Final answer is 30.</u></em>
Hope this helps!

Answer:
Explanation:
1 mile=5280 ft
1 hour=3600 seconds
Changing speed from mi/h to ft/s

Time of flight, 
From fundamental kinematics equations
where g is acceleration due to gravity whose value is taken as 32.2 ft/s2 and h is the distance
By substitution
