Estimated total energy output IN ONE SECOND = 5 x 10²⁶ Joules .
Energy = mass · c² ( Albrecht Einshtein)
c = 3 x 10⁸ m/s
c² = 9 x 10¹⁶ m²/s²
5 x 10²⁶ Joules = mass · (9 x 10¹⁶ m²/s²)
mass = (5 x 10²⁶ Joules) / (9 x 10¹⁶ m²/s²)
mass = (5 x 10²⁶) / (9 x 10¹⁶) kg
mass = (0.55... x 10¹⁰) kg
<em>mass = 5.55... x 10⁹ kilograms</em>
Look at that for a second. Then think about it for another second.
It's telling us that at its present rate of energy output, the sun is losing more than 5 and a half Billion kilograms of mass every second. And when we read other things about the sun, they say that the sun is expected to continue doing what it's doing for another 4 or 5 Billion years !
Gives ya some idea of the size and mass of the Sun, doesn't it !
Driving a motor........
chemical energy is converted into kinetic energy.
Falling off of cliff
.........gravitational potential energy is converted into kinetic energy.
Hydroelectric energy generation
.......gravitational potential energy is converted into kinetic energy (i.e. driving a generator), which is then converted into electrical energy.
Nuclear power generation
.........mass is converted into energy, which then drives a steam turbine, which is then converted into electrical energy.
Answer:
es la energia que se obtiene del vientoo,dicho de otro modo,es el aprovechamiento de la energia cinetica de las masas de aire
Explanation:
Answer:
a. Amplitude = 0.244 meters
b. Period = 1.62 seconds
c. Frequency = 0.6173 Hz
Explanation:
a.
With the position goes from 0.122 meters to -0.122 meters (negative because it is in the opposite side of the equilibrium point), the amplitude is the maximum value minus the minimum value:
Amplitude = 0.122 - (-0.122) = 0.122 + 0.122 = 0.244 meters
b.
The period is the amount of time the object takes to arrive in the same position again. So, if it takes 0.81 seconds to go to -0.122 m, it will take another 0.81 seconds to come back to 0.122 m, so the period is the sum of these two times:
Period = 0.81 + 0.81 + 1.62 seconds
c.
The frequency of the movement is the inverse of the period:
Frequency = 1 / Period
So if the period is 1.62 seconds, the frequency is:
Frequency = 1 / 1.62 = 0.6173 Hertz
