Answer:
In space we feel weightlessness because the earth's gravity has less effect on us. The Earth's gravitational attraction at those altitudes is only about 11% less than it is at the Earth's surface. If you had a ladder that could reach as high as the shuttle's orbit, your weight would be 11% less at the top.

Answer:
To take part of a whole number Ex: 10% of 30 is 3
Answer:
The answer is below
Explanation:
Distance is a measurement of how far apart two points are. Distance is a scalar quantity, i.e. it has magnitude and no direction.
Total distance traveled = distance traveled north + distance traveled east + distance traveled south
Total distance traveled = 100 + 50 + 60 = 210 meters
Displacement is the shortest distance between the starting and end points.
displacement² = 50² + (100 - 60)²
displacement² = 2500 + 1600
displacement = 64 meters
The displacement of the journey is vector, because displacement is a vector quantity.
The distance between P and R is equal to the net displacement of the ship in going from port P to port R
Vector P = 30 km North
Vector R = 20 km 30° east of north
Now, the angle between Vector P and vector R = 90° + 30 ° = 120°
Using the formula to find the addition of two vectors:
Resultant =
Plugging the values:
Resultant = 26.457 Km
The distance from P to R is 26.457 km
