The gravitational force, Fbetween an object and the Earth is inversely proportional to the square of the distance from the objec
t to the center of the Earth. If an astronaut weighs 214 pounds on the surface of the Earth, what will this astronaut weigh 500 miles above the Earth? Assume that the radius of the Earth is 4000m / l * es Round off your answer to the nearest pound)
We can calculate the weight of the astronaut since we know the relationship between both variables (weight and radius), so we establish the following proportion:
The astronaut's initial weight is 214 pounds (W1), the radius is 4000 miles (R) and the distance is equal to 500 miles, we substitute and calculate the new weight of the astronaut as follows:
efficiency of a machine is less than 100% because some part is energy is utilized to overcome some opposing forces like friction which is wasted as heat ,sound energy etc
Because: the oesophagus is the throat and the mouth is how the food gets to the oesophagus. might be wrong because I'm not sure about the organ part but I'm pretty sure that's all it could be
I believe the best example of Newton's First Law of motion would be the example or illustration with the basketball player. An object will move in a straight line or a given direction at a constant speed unless or until another force acts upon the object, causing a change in speed and or direction.
