It takes the person 5 seconds to move 10 meters What is the power output?
Power output is calculated by dividing the work done by the time taken to do that work. In this case, work done is equal to force multiplied by distance, which is mass multiplied by acceleration due to gravity multiplied by distance. Given that the person takes 5 seconds to move 10 meters, we can calculate the speed at which they are moving. Once we have the speed, we can determine the power output using the formula for power, which is work done divided by time.
What is the area of a right triangle with a hypotensuse of 32 cm and one leg of 30 cm round your answer to the nearest unit if necessary?
Using Pythagoras' theorem and the area formula it is: 167 square cm to the nearest unit.
How do you factorize using the quadratic formula?
simplify.
What is the answer by using the quadratic formula 2a -46a plus 252 0?
The answer of the equation 2a -46a plus 252 = 0 using the quadratic formula is a = 5.25.
Which is the output for the input -2 using the rul y equals 4x plus 2?
-6
How do you find power output?
by using tester
How does Strava calculate power for cycling activities?
Strava calculates power for cycling activities by using a formula that takes into account factors such as speed, weight, and elevation gain. This formula estimates the power output of a cyclist based on these variables recorded during the ride.
What is the efficiency of a dc generator that requires 200 watts of energy to supply 160 watts of output power?
The efficiency of a DC generator can be calculated using the formula: Efficiency (%) = (Output Power / Input Power) × 100. In this case, the input power is 200 watts and the output power is 160 watts. Thus, the efficiency is (160 W / 200 W) × 100 = 80%. This means the generator operates at 80% efficiency.
What is a disadvantage in using tidal energy?
its power output is not predictable
A weightlifter is able to lift 250 kg 2.00 m in 2.00 seconds What is his power output?
Power output can be calculated using the formula: Power = Work / Time. The work done in lifting the weight is equal to the gravitational force (weight) multiplied by the height lifted: Work = Force × Distance = (250 kg × 9.81 m/s²) × 2.00 m = 4905 J. Therefore, the power output is 4905 J / 2.00 s = 2452.5 W. So, the weightlifter's power output is approximately 2453 watts.
How does a bike power meter work to measure the power output of a cyclist?
A bike power meter measures the power output of a cyclist by using strain gauges to detect the force applied to the pedals. This data is then combined with the speed of the cyclist to calculate power output in watts.
What is the watts if a 12 volt battery produces 2.7 amps?
The power output of a 12-volt battery producing 2.7 amps can be calculated using the formula: Power (watts) = Voltage (volts) x Current (amps). So, in this case, the power output would be 12 volts x 2.7 amps = 32.4 watts.
What is the mechanical output power while lifting a 300 gram mass 60 centimeters?
Not enough information. You can calculate the work (using the formula for potential energy), but to calculate the power, you would also need the time (how fast is this done?)
What is the formula for calculating the efficiency of a heat pump?
The formula for calculating the efficiency of a heat pump is the ratio of the heat output to the energy input, expressed as a percentage. It can be calculated using the formula: Efficiency (Heat Output / Energy Input) x 100.
How do bike power meters work and measure the power output of a cyclist?
Bike power meters measure the power output of a cyclist by using strain gauges to detect the force applied to the pedals or crank arms. This data is then combined with the speed of the cyclist to calculate power output in watts.
What is the efficiency formula of lever?
The efficiency of a lever can be calculated using the formula: Efficiency = (output force × output distance) / (input force × input distance) * 100%. It represents the ratio of the output work done by the lever compared to the input work applied to the lever.
What type of energy is formed when using a cassette player or recorder?
The main power output is in the form of heat but a small amount of power is also output as an electrical signal.
