3. You are to determine the power rating of the motor in an elevator system. The elevator (with a full load) weights 1700 kg and

is required to move upward 3 m/sec at constant speed. The lifting mechanism is 90% efficient (i.e., 10% of the power generated by the motor is wasted in the mechanism, e.g., for overcoming friction). What is the minimum output power rating in HP of the motor that meets the requirement?

What is the minimum output power rating in HP of the motor that meets the requirement?The Elevator (with A Full Load) Weights 2000 Kg And Is Required To Move Upward 3 M/sec At Constant Speed. The Lifting Mechanism Is 85% Efficient (i.e., 15% Of The Power Generated By The Motor Is Wasted In The Mechanism, E.g., For Overcoming Friction).

Whqt do you mean by geo-stationery satellite? Explain.​
Ratling [72]

Answer:

Description: When a geosynchronous satellite is placed directly above the Equator with a circular orbit and angular velocity identical to that of the Earth, the satellite is known as a geostationary satellite

Explanation:

These satellites appear to be stationary above a particular point which is due to the synchronization. This type of satellite provides a distinct benefit of fixing the receiving antennas at one place, hence making them more economical than regular tracking antennas. Over the years, these satellites have helped in revolutionizing the global communications, weather forecasting and television broadcasting. When the orbit of a geosynchronous satellite is not aligned directly over the equator, the orbit is known as an inclined orbit.

What is the production​ function? The production function is the relationship between
Ludmilka [50]

Answer:

The Production Function is the relationship between the quantity or variables of output and the different inputs quantities used in the production process.

Explanation:

Generally in quality, production or any business, we need to know what is the output with respect to different input variables. Suppose if an output is about bottle produce per hour, then we look at the inputs such as temperature, raw material/inventory, power supply, manpower, etc which are needed to produce bottle. any changes, for example in temperature could change the production rate.

Furthermore, a graph is made to see the production function.

A hunter is standing on flat ground between two vertical cliffs that are directly opposite one another. He is closer to one clif
Ugo [173]

Answer : distance, d = 463.7 m

Explanation :  

According to the given condition it can be assumed that the first echo would be heard from closest cliff. The second echo is from farther cliff and the third echo is from the reflection between the two cliffs.

Let the distance between the first cliff and the point of firing is x and y is the distance between the second cliff and the point of firing.

Then the first echo will travel 2x distance, second will travel 2y distance and third will travel 2x +2y.

So, using above data :

2y=v\times t_3

and

2x=v(t_2+t_3)

On solving :

y=\dfrac{343\times0.827}{2}

y=141.8\ m

x=\frac{343\times(1.05+0.827)}{2}

x=321.9\ m

x = 321.9 m and y = 141.8 m

Hence, total distance between two cliffs is d = 321.9 m + 141.8 m = 463.7 m
