Thermal energy is defined as the total kinetic energy of all particles in an object. Even though the cup of water has a higher temperature, the bathtub has more thermal energy because it contains much more mass of water compared to the cup.
Answer:
A. The rate of heat transfer through the material would increase.
Explanation:
To calculate the heat transfer in a heat exchanger you decide that there is not heat leakage to the surroundings, that means that magnitude of the two transfer rates will be equal. Any heat lost by the hot fluid, is gained by the cold fluid. The equation that describes this is Q = m×Cp×dT
Where:
heat = mass flow ×specific heat capacity × temperature difference
So if we increase the rate of flow of cooling water and the other variables that ypu can control remain the same, the result is that the rate of heat transfer through the material would increase, as it is stated in option a.
Answer:
Hey there!
This is already rounded to four significant figures!
Zeroes after the decimal but before the 7 don't count, and 7, 0, 6, and 2 count as significant figures.
So, the answer would be 0.007062.

Explanation:
En 1945, durante la Segunda Guerra Mundial, dos ciudades japonesas; Hiroshima y Nagasaki fueron bombardeadas con bombas atómicas durante el ataque ofensivo.
Hiroshima fue bombardeada el 6 de agosto de 1945 mientras que Nagasaki fue bombardeada el 9 de agosto de 1945.
Las bombas provocaron la muerte instantánea de aproximadamente 120.000 personas y obligaron al emperador japonés a rendirse incondicionalmente.
