Answer:
3
Explanation:
From the question given above, the following data were obtained:
Effort = 5 N
Resistance = 15 N
Mechanical advantage =?
Mechanical advantage is simply defined as the ratio of the resistance to the effort. Mathematically, it can be expressed as:
Mechanical advantage = Resistance /Effort
With the above formula, we can obtain the mechanical advantage as follow:
Effort = 5 N
Resistance = 15 N
Mechanical advantage =?
Mechanical advantage = Resistance /Effort
Mechanical advantage = 15 / 5
Mechanical advantage = 3
Answer:
The ratio of T2 to T1 is 1.0
Explanation:
The gravitational force exerted on each sphere by the sun is inversely proporational to the square of the distance between the sun and each of the spheres.
Provided that the two spheres have the same radius r, the pressure of solar radiation too, is inversely proportional to the square of the distance of each sphere from the sun.
Let F₁ and F₂ = gravitational force of the sun on the first and second sphere respectively
P₁ and P₂ = Pressure of solar radiation on the first and second sphere respectively
M = mass of the Sun
m = mass of the spheres, equal masses.
For the first sphere that is distance R from the sun.
F₁ = (GmM/R²)
P₁ = (k/R²)
T₁ = (F₁/P₁) = (GmM/k)
For the second sphere that is at a distance 2R from the sun
F₂ = [GmM/(2R)²] = (GmM/4R²)
P₂ = [k/(2R)²] = (k/4R²)
T₂ = (F₂/P₂) = (GmM/k)
(T₁/T₂) = (GmM/k) ÷ (GmM/k) = 1.0
Hope this Helps!!!
The airplane's speed relative to the ground is
√ (100² + 25²)
= √ (10,000 + 625)
= √ 10,625
= 103.08 km/hr .
The angle of its velocity north of west is
the angle whose tangent is (25/100)
arctan(25/100) = 14° north of west .
(bearing = 284°)
Answer:
9.7 ms⁻¹
Explanation:
The formula to find the acceleration is :
According to the question, we are asked to find the Final Velocity.
For that, let the Final Velocity be x.
Therefore,
Final velocity = 9.7ms⁻¹
