Answer: Yes and no.
Explanation: Mass is the amount of matter in an object, whereas weight is the force exerted on an object by gravity. Objects on the surface of the earth have weight, although sometimes the weight is difficult to measure.
Answer:
State vector.
Explanation:
To determine exactly where a satellite is located, engineers must think and calculate positions in three dimensions. A set of data telling engineers all of the various elements of position, velocity, and time for a satellite or spacecraft is known as a state vector.
This ultimately implies that, state vectors gives a detailed description of the position and velocity of a satellite at a specific period of time. Also, the more accurate your input state vector, the more accurate would be the position, velocity and time for a satellite when trying to determine its location. Therefore, the time tag of a state vector shouldn't be too far from the present time of the day.
Answer:
The radius of the loop is 20.66 km
Explanation:
let the radius of the loop be r
mass of airplane is m
At the top, the pilot experiences two radial forces, which are
1) Gravitational force is mg
2) Centrifugal forces mv²/r out of the center
When the pilot experiences no weight,
then, mg = mv²/r
r = v² / g
= 450² / 9.8
= 20.66 x 10³3
= 20.66 km
Commonly referred to as the Mississippi River DELTA. technically, it's an estuary.
