Answer: 9/4n
Explanation:
Let's take T to represent tank
When n litres of fuel was added to tank that was 1/3 full = n + 1/3T
The tank was 7/9T
n+1/3T = 7/9T
n =7/9T - 1/3T
n = 4/9
If a full tank is taken to be 1 = 9/9
Hence, we will have 1 = x × n
1 = x × 4/9
x = 9/4
Hence 9/4 of n = 9/4n
Answer:
The correct answer is Separating soils by grain size. Among all the other choices, this is the aspect of soil characteristics in which a soil triangle is used for.
Explanation:
Vertical force on the box=mg
<span>the component of gravity parallel=mg*SinTheta </span>
<span>the component of gravity normal=mg*CosTheta </span>
<span>frictional force up the plane: mg*cosTheta*mu max, but if it is sitting still, it is equal and opposite to mg*cosTheta (it cannot be greater than this or it would go up the plane).</span>
Answer:
A) R = 1019.11 Ω
B) V = 101.91 V
Explanation:
a) The resistance is given by the formula;
R = ρL/A
Where;
ρ is bulk density = 5.0 Ωm
L is length of cylinder = 1.6m
A is area = (π/4)D² = (π/4) x 0.1² = 0.007854 m²
Plugging in the relevant values, we obtain ;
R = (5 Ωm x 1.6m)/(0.007854 m²)
R = 1019.11 Ω
b) potential difference is given by;
V = RI
Thus, plugging in relevant values, we obtain;
V = 1019.11 Ω ∙ 0.1A
V = 101.91 V
