The llama's weight is (90 x 9.807) newtons.
To raise it 500 meters requires (90 x 9.807 x 500) joules of energy.
If energy is supplied at the rate of 80 watts, then the time required is
(90 x 9.807 x 500)/(80) = 5,516 seconds = 91minutes 56seconds

How does force affect power output?
Force affects the speed of power output. If the driving force is slow, the speed of power output will also be sluggish. Alternatively, if the driving force is fast, power output will be able to match the speed.
A weightlifter raises a 90-kg barbell from the floor to a height of 2.2 m in 0.6 s What was his average power output during the lift?
42
How is energy efficiency determined?
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
Why can the power output vary for photocells?
because it does
What is the minimum output power of Creative Technologies speakers?
Creative Technologies speakers com from different prices, size, color, and materials. The minimum output power of Creative Technologies speakers is eighteen watts.
What opportunities does Clinical research courses offer?
The output signal-to-noise ratio is defined as the ratio of the average output signal power to the average output noise power. From Equation (2.140), we see that the message component in the discriminator output, and therefore the low-pass filter output, is
What is the average output pressure for car Power Steering Pump?
1000psi
If you do work on an object in half the time, your power output is?
If you do work on an object in half the your power output is
How do you find power input with given power factor and power output?
Output Power divided by Power Factor.
What is the average power output of a BSA engine?
A BSA, or Birmingham Small Arms, engine ranges from 125cc to 175cc, making the average output 150cc. The 125cc engines were manufactured in 1948 and the engines became increasingly more powerful.
What difference between RF power output watt and electrical power output watt?
The difference is in the output frequency.
Can A Computer Output Electricity In Computercraft you can say if true output power on this side Can you say in a program to output power say to light a light So if true then output power to led's?
A Computer Output Electricity in Computercraft cannot be said to make a program to output power, regardless of the side.
How does force affect power output?
Force affects the speed of power output. If the driving force is slow, the speed of power output will also be sluggish. Alternatively, if the driving force is fast, power output will be able to match the speed.
What are the mechanical and electrical characteristics of a DC shunt motor?
mechanical characteristics can be drawn between speed and torque electrical characteristics are 1. Output power vs speed 2. Output power vs input power 3. Output power vs efficiency 4. Output power vs torque 5. Output power vs line current
Is power supply input or output devices?
Output - because it is outputting power to the rest of the device
What does peak power and continuous nominal power handling in car speakers?
Peak power is the highest rated output of the speaker when loud (or peak) parts hit. Continuous/nominal power is the average output at normal and continuous listening levels. If you have the Peak Power rating, you can figure out the nominal level by multiplying the peak power by the square root of two (0.707). Peak Power * 0.707 = Nominal Power.
