<span>Given:
Hmax (distance) = 50.0m
v</span>₀ = <span>70.0m/s
Required:
what angle should the arrow make with the horizontal as it is being shot
Solution:
Hmax = v</span>₀²sin²θ / 2g
sin²θ = 2gHmax / v₀²
sin²θ = 2 (9.81 m/s²) (50m) / (70 m/s)²
sin²θ = 0.200
θ = 26.56°
It is the same if no external forces are added , that’s your answer.
The answer is Design texture.
Hair with directional wave patterns or motion illusions. When designing a style, design texture must be considered. Curly hair reflects less light and has a greater shape than straight or wavy hair.
What is Design texture?
- Texture is a design feature that delineates the surfaces of shapes and forms.
- Tactile texture is texture that you feel with your fingertips, whereas visual texture is texture that an artist recreates on a flat surface.
- Because it possesses height, breadth, and depth, tactile texture is three-dimensional.

Answer:
F= 5.71 N
Explanation:
width of door= 0.91 m
door closer torque on door= 5.2 Nm
In order to hold the door in open position we need to exert an equal and opposite torque, to the door closer torque, on the door.
so wee need to exert 5.2 Nm torque on the door.
If we want to apply minimum force to exert the required torque we need to apply force perpendicularly on the door knob (end of door) so that to to greater moment arm.
T= r x F
T= r F sin∅
F= T/ (r * sin∅)
F= 5.2/ (0.91 * 1)
F= 5.71 N
