Hello!</h2>
The answer is A. Chemical energy to heat energy to kinetic energy to electrical energy.
<h2>
Why?</h2>
Let's check the energy conversion given in the statement:
Chemical energy: Chemical energy is usually obtained from a natural resource combustion. For this particular case is the result of natural gas combustion.
Heat energy: Heat energy comes from chemical reactions such as natural gas combustions.
Kinetic energy: Kinetic energy is obtained by turbines transforming the pressurized steam on mechanical movement. Turbines are formed by a turbine that absorbs the heat energy to do mechanical work and transmit it to an output rotating shaft.
Electrical energy: Electrical energy is generated by gas turbines when the rotating output shaft is connected to an electrical generator. Electrical generators use mechanical energy to generate electrical energy by using electromagnetic induction. Electrical generators are basically formed by a rotor and a stator.
Have a nice day!
Answer:
The correct option is (A).
Explanation:
When the temperature of the hot solid object increases then the radiation which emits from it gets shifted to smaller wavelength or higher frequencies. The hot appears red color.
The total energy emitted of a hot solid object is directly proportional to the fourth power of the temperature of the black body.
For example, when we switch on the light bulb, initially the radiation of the bulb appears dimmer. Then, it will become brighter. Then, it will turn yellow and then it becomes even white.
The color of the light emitted by a hot solid object depends on the temperature of the object.
Therefore, the correct option is (A).
Answer:3.49 m/s
Explanation:
Given
Speed of marble at Bottom
Diameter of loop
As Energy is conserved therefore Energy at top is equal to energy at bottom
,where is the velocity at bottom
Answer:
unit (v) = [ -0.199 i - 0.8955 j + 0.39801 k ]
Explanation:
Given:
v = (-23.2, -104.4, 46.4) m/s
Above expression describes spacecraft's velocity vector v.
Find:
Find unit vector in the direction of spacecraft velocity v.
Solution:
Step 1: Compute magnitude of velocity vector.
mag (v) = sqrt ( 23.2^2 + 104.4^2 + 46.4^2)
mag (v) = 116.58 m/s
Step 2: Compute unit vector unit (v)
unit (v) = vec (v) / mag (v)
unit (v) = [ -23.2 i -104.4 j + 46.4 k ] / 116.58
unit (v) = [ -0.199 i - 0.8955 j + 0.39801 k ]
