Answer:

5524.8 m/s

Explanation:

Given that,

Altitude above the surface of earth is 6679 km, the Space Station can complete one orbit in 1.5 hours. We need to find the average speed of the ISS. The average speed of its orbit is given by :

v=\sqrt{\dfrac{GM}{R}}

R is distance from Earth

R = r + d, r is the radius of Earth

R = 6371  + 6679

R = 13050 km

So,

v=\sqrt{\dfrac{6.67\times 10^{-11}\times 5.972 \times 10^{24}}{13050\times 10^3}}\\\\v=5524.8\ m/s

or

Hence, the average speed of ISS is 5524.8 m/s.

Which best describes how many americans depend on ground water for drinking water
kondaur [170]

Answer:

About half or more

Explanation:

Over 50% of the United States population depends on groundwater for drinking water. Groundwater is also one of our most important sources of water for irrigation.

About 115 million people—more than one-third of the Nation's population—rely on groundwater for drinking water.

What is uniforlmly acelerated motion and uniform motion​
steposvetlana [31]

Uniformly Accelerated motion : When a body moves along a straight line and its velocity increases by equal amounts in equal interval of time then the motion is called uniformly accelerated motion. E.g.:- Motion of a freely falling body.

Uniform Motion : When a body covers equal distances in a straight line, equal intervals of time are called uniform motion. Example: a car moving at 20km/h in a straight line. When a body covers unequal distance in equal intervals of time in a straight line is called non-uniform Example : spinning wheel.

<h3>Difference About Uniformly Accelerated motion And Uniform Motion</h3>

In Uniform Velocity Motion a body will be moving with a constant /unchanging velocity moving in a particular direction and thus acceleration will be zero whereas in Uniform accelerated motion a body will move at constant acceleration and its velocity will keep changing with time at a constant/ steady rate.

Both speed and velocity measure how fast something is moving. However, since speed is not a _________ it does not require a(n) _
Jet001 [13]

Both speed and velocity measure how fast something is moving. Hence, since speed is not a vector it does not require direction.

Speed only depends on the distance covered by the object and how much time it took to cover that distance. It does not care about the direction, it just depend on the length of the entire path covered. Whereas, velocity depends on magnitude as well as the direction of the object's motion for example: When an airplane is traveling, It is better to deal the motion with velocity and when we are moving in a car inside the city, we should deal the motion with speed.
