Answer:
Vectors have both magnitude and direction
Explanation:
Vectors show how strong the force in because the bigger the arrow, the stronger the force. Also, it obviously shows direction because its an arrow.
Explanation:
The aircraft is traveling north at 100 m/s.
The wind blows from the west (towards the east) at 25 m/s.
The two vectors form a right triangle. The magnitude of the resultant velocity can be found with Pythagorean theorem:
v² = vx² + vy²
v² = (25 m/s)² + (100 m/s)²
v = 103 m/s
The direction can be found with trigonometry:
θ = atan(vy / vx)
θ = atan(100 / 25)
θ = 76.0°
The resultant velocity is 103 m/s at 76.0° north of east.
i dont know but i need the points soory may god bless you
Answer:
Increases....because you get closer to the core :)
Its weight is 10g . The 'g' is the acceleration of gravity
wherever the object happens to be at the time.
On Mars, g=3.71 m/s², the object weighs 37.1 newtons.
On the Moon, g=1.62 m/s², the object weights16.2 newtons.
On Earth, g=9.81 m/s², the object weighs 98.1 newtons.
