Answer:
To reach the goal to be Eco friendly, the designer must not harm the ecosystem of surrounding in any ways.
Explanation:
- Friendly design means that the hotel must not harm the surrounding ecosystem in any way.
- The hotels' energy consumption shall be fulfilled by the use of renewable resources like solar, wind energy, etc.
- Proper disposal of wastage is the most important term.
- No, chemicals are used inside the premises of the hotel for any purpose of cleaning, washing, etc.
- The designer must place a garden with grass, trees, and flowers for the fresh air of the hotel.
Answer:
Explanation:
Work done by torque is given as
Word one = torque × angular displacement
W = τ × θ
Given that,
τ = 2000Nm
Mass of motor = 300kg
Radius r = 55cm = 0.55m
Work done by wheel in first t= 23second.
Now we need to find the angular displacement
We know that,
τ = I•α
Moment of inertia of wheel
I = MR²
I = 300 × 0.55²
I = 90.75 kgm²
Then, τ = I•α
α = τ / I
α = 2000/90.75
α = 22.04rad/s²
Then, using circular motion,
∆θ = wit + ½αt²
wi = 0rad/s
∆θ = ½αt²
∆θ = ½ × 22.04 × 23²
∆θ = 5829.2 rad.
Then,
Work done?
W = τ × θ
W = 2000 × 5829.2
W = 1.17 × 10 ^7 J
The approximate acceleration of gravity for an object above the earth's surface is 9.8 m/s².
<h3>
Acceleration due to gravity </h3>
The acceleration due to gravity of an object above the Earth's surface is calculated from Newton's second law of motion and Newton's law of universal gravitation.
<h3>Force between the object and Earth</h3>

<h3>Weight of the object</h3>

Solve (1) and (2)
mg = GmM/R²
g = GM/R²
where;
- M is mass of Earth
- G is gravitational constant
- R is radius of the Earth = 6,371 km
g = (6.673 x 10⁻¹¹ x 5.98 x 10²⁴)/(6,371 x 10³)²
g = 9.8 m/s²
