Drag is passive, therefore it does not act on gravity. Drag is a mechanical resistance to motion. If the motion in question was induced by gravity drag it can impede that motion, but has no effect on the gravity.
hope this helps!
Answer:
An apple, potato, and onion all taste the same if you eat them with your nose plugged
Explanation:
Answer:
F₃ = -151 N i + 96 N j
Explanation:
Newton's second law:
∑F = m*a Formula (1)
∑F : algebraic sum of the forces in Newton (N)
m : mass s (kg)
a : acceleration (m/s²)
Forces acting on the object
F₁= 3.0 N i + 16.0 N j
F₂ = -12.0 N i+ 8.0 N j
F₃ = F₃x N i +F₃ y N j
x component of the net force on the object
Fx=F₁x+F₂x+F₃ x
Fx = 3.0 N-12.0 N +F₃x
Fx = F₃x - 9 N
y component of the net force on the object
Fy=F₁y+F₂y+F₃ y
Fy =16.0 N+ 8.0 N +F₃y
Fy = F₃y + 24 N
Newton's second law to the object:
a = -8 m/s² i + 6.0 m/s² j
∑Fx = m*ax m=20 kg , ax = -8 m/s²
F₃x - 9 = 20 *(-8)
F₃x = -160+9
F₃x = -151 N
∑Fy = m*ay m=20 kg , ay = 6 m/s²
F₃y + 24 =20*( 6 )
F₃y =120 - 24
F₃y = 96 N
F₃ = -151 N i + 96 N j
Answer:
They developed a test for poisons in the human tissues
Explanation:
Around the 19th century, Mathieu Orfila and Robert Christison developed important tests that identified poisons in human tissues.
By so doing, they laid the foundation for what is now called forensic toxicology. This science attempts to identify poisons in human tissues especially by way of autopsies and forensic investigation.
Today forensic toxicology has expanded to include alcohol testing techniques as well as testing athletes for intake of performance enhancing substances.
