The answer is A bc I did the quiz and I got it right
The banking angle of the curved part of the speedway is determined as 32⁰.
<h3>
Banking angle of the curved road</h3>
The banking angle of the curved part of the speedway is calculated as follows;
V(max) = √(rg tanθ)
where;
- r is radius of the path
- g is acceleration due to gravity
V² = rg tanθ
tanθ = V²/rg
tanθ = (34²)/(190 x 9.8)
tanθ = 0.62
θ = arc tan(0.62)
θ = 31.8
θ ≈ 32⁰

Answer:
extream heat and pressre split apart
<span>m1 = 5g = 0.005kg
v1 = 0
m2 = 1.0 x 10^-7g = 1.0x10^-10kg
v2 = 7.5
v3 = ?
looks like you did the formula correctly
m1v1 + m2v2 = (m1+m2)v3
0 + m2v2 = (m1+m2)v3
m2v2 / (m1+m2) = v3
(1.0x10^-10)(7.5) / (0.005 + 1.0x10^-10) = v3
1.5x10^-7 = v3
However, it said the bee gets hit by 1000 pollen grains, so I would guess you have to multiply 1.0 x 10^-10 by 1000 first, unless the total mass of the 1000 grains really is 1.0 x 10^-10.</span>
