<span>Usually, If you drop a 200 gram piece of metal with a temperature of 110 degrees Celsius into 1000 grams of water at 25° Celsius, the statement which would best describe what would occur is the last one : </span><span>The water and the metal's temperatures will reach the same temperature. I choose this one because this is a nice example of how the nature tries to reach the balance. Hope it helps! Regards.</span>
Answer:
26 V
Explanation:
Given:
The three resistors 5.5 V. 8.2 V. and 12,3 V. are connected in series.
Now we have to find out the source voltage to which these resistors arc connected ?
Solution:
As we know in series the magnitude of current is uniform but the voltage divides between the resistors supplied from source voltage.So the magnitude of source voltage is, 5.5 V + 8.2 V + 12.3 V = 26 V
Hence, the value of the source voltage to which these resistors are connected is 26 V
Answer:
Halving the wavelength doubles the frequency and, thus, doubles the energy of the incident photons. This doubles the energy given to each electron, nearly doubling its kinetic energy after it is free from the metal.
Answer:
Technician A is absolutely correct that the valve spring should be kept with the valve at the time of disassembly and tested for squareness and proper spring force.
Technician B is not correct because the size of exhaust valve is about 75-80% of the intake valve for proper functioning.
Explanation:
The law of conservation of energy states that: "For an isolated system, the total amount of energy is conserved."
For the given system:
Total energy = potential energy + kinetic energy
At the highest point of the swing:
kinetic energy is zero and potential energy is maximum
Total energy = 295 + 0 = 295 J
At the lowest point of the swing:
kinetic energy is maximum and potential energy is zero. Total energy is the same, therefore:
295 = 0 + kinetic energy
kinetic energy = 295 J
