Answer: The expression simplified is this 2.25x-10.4
True, they do make a 90 degree angle and we can positively agree the second line is MIXM2=1
Answer:
Θ =tan⁻¹ (4KQ²/mgr²), Q = r[mgtanΘπ∈₀]
Step-by-step explanation:
initially the angle Θ=0° ,the vertical forces were equal to product of mass and gravity(m*g) and there was no horizontal or lateral force in action. But after the displacement of balls new forces are induced.
X-Axis:
Fe = TsinΘ
[KQ²/(r/2)²] = TsinΘ where r₁=r/2, r₁ = new distance
(4KQ²/r²) = TsinΘ
Y-Axis
TcosΘ = mg
As we know that tanΘ=sinΘ/cosΘ
We have, tanΘ = 4KQ²/mgr²
By adjusting this equation and putting K=1/4π∈₀ we get,
Q = r[mgtanΘπ∈₀]
Answer:
v=452.16
Step-by-step explanation:
use the cone volume formula: V=πr^2
v=3.14*6^2*12/3
v=3.14*36*4
v=452.16
No, He is already 18 miles ahead of her, if she were to run faster than Him it would take 2.62 hours.
