It is difficult to calculate the exact amount of energy produced when shouting at 120 decibels, as it depends on various factors such as the duration and intensity of the shout. However, shouting at such a high decibel level requires a significant amount of energy from your vocal cords and lungs.
The useful energy produced by the motor can be found by multiplying the input energy by the efficiency. Therefore, 250 J * 0.4 = 100 J of useful energy produced by the motor.
It's 10 times louder. It is easily looked up.. Example of source: http://www.howstuffworks.com/question124.htm
The energy produced by converting 10 kg of mass into energy is calculated using Einstein's famous equation E=mc^2. For 10 kg of mass, the energy produced would be approximately 9 x 10^17 joules.
The amount of energy produced by electrical energy depends on the source of the electricity. For example, a wind turbine or solar panel will produce a certain amount of energy based on their capacity and efficiency. The energy produced can be calculated in kilowatt-hours (kWh) or joules, depending on the context.
The amount of heat energy produced from electrical energy depends on the efficiency of the system. If we assume 100% efficiency, then all 3000 joules of electrical energy would be converted into heat energy. Thus, 3000 joules of electrical energy would produce 3000 joules of heat energy.

110 decibels means (1011 or 100,000,000,000) times as much as you started with.
we can not tell how much wind is bein produced
73 % is electrical energy
less then 1%
A decibel isn't a definite amount of anything. It's a unit used to compare two powers. 1 decibel more = 25.89% more power 3 decibels more = twice as much power 3 decibels less = half as much power 10 decibels more = 10 times as much power 10 decibels less = 0.1 as much power 20 decibels more = 100 times as much power You don't know how much any number of decibels is until you know what it's compared to.
Take a sound pressure level meter and measure it. 95 decibels means over the is 0 decibels is the threshold of hearing. 95 decibels means the measure over 0 decibels.

The useful energy produced by the motor can be found by multiplying the input energy by the efficiency. Therefore, 250 J * 0.4 = 100 J of useful energy produced by the motor.
