Answer:
potential energy is transformed into kinetic energy
When setting up a circuit with temperature control, the first one you should consider for temperature control is a thermocouple. A thermocouple sends a signal for the temperature reading and received by another thermocouple to send another signal to adjust the temperature if it is below or above the set temperature.
Answer:
Explanation:
The first case relates to open end pipe with fundamental frequency . Let the length of flute be l . The length vibrating column is l .
λ = v / n where n is frequency , v is velocity of light and λ is wavelength of sound produced .
λ = 343 / 261.6
= 1.31 m .
For fundamental frequency
λ / 2 = l
l = λ / 2
= 1.31 / 2
= .655 m
= 65.5 cm .
b )
Nearby colder room will create lower frequency because velocity of sound will be smaller .
frequency of note produced = 261.6 - 3 = 258.6 Hz .
velocity of sound v = n λ
= 258.6 x 1.31 m
= 338.76 m /s
decrease of velocity = 343 - 338.76 = 4.24 m /s
1 degree change in temperature produces a change of .61 m/s change in velocity .
decrease in temperature = 4.24 / .61
= 7⁰C
Temperature of colder room = 20 - 7 = 13⁰C .
Answer:
A, B, D.
Explanation:
If Jamy pushes on Anita, then by Newton's 3rd Law there will be a reaction force equal in magnitude and opposite in direction. This means that A and D are correct, while C, E, F and G are incorrect. Since the magnitude of any of these forces can be calculated with Newton's 2nd Law, F=ma for either Jamy or Anita, this means that B is correct.
Answer:
The correct option is: Total energy
Explanation:
The Hamiltonian operator, in quantum mechanics, is an operator that is associated with the<u> total energy of the system.</u> It is equal to the sum of the total kinetic energy and the potential energy of all the particles of the system.
The Hamiltonian operator was named after the Irish mathematician, William Rowan Hamiltonis denoted and is denoted by H.
