. The inner and outer surfaces of a 4-m × 7-m brick wall of thickness 30 cm and thermal conductivity 0.69 W/m-K are maintained a
Anni [7]

Answer:

\frac{dQ}{dt} = 966 W

Explanation:

As we know that the rate of heat transfer due to temperature difference is given by the formula

\frac{dQ}{dt} = \frac{KA(\Delta T)}{L}

here we know that

K = 0.69 W/m-K

A = 4 m x 7 m

thickness = 30 cm

temperature difference is given as

\Delta T = 20 - 5 = 15 ^oC

now we have

\frac{dQ}{dt} = \frac{(0.69W/m-K)(28 m^2)(15)}{0.30}

\frac{dQ}{dt} = 966 W

A single brick falls with acceleration g. The reason a double brick falls with the same acceleration is
LekaFEV [45]

The reason is because the force due to the acceleration from gravity is constant. It's the same as the typical "dropping a bowling ball and feather (with no air resistance) at the same time". Gravity acts on all object with the same acceleration regardless of physical properties.

Summarize: Based on what you have learned, how will the sound that the observer hears
Reil [10]

Answer: The sound will change due to changes in frequency and the wavelength of the airplane.

Explanation: Let assume that the observer is at a stationary position. The wavelength of the sound from the airplane reduces and the frequency increases as the plane is moving toward the observer. As the airplane passes by, that is, moving away from the observer, the frequency starts to reduce while the wavelength of the sound starts to increase.

The sound that the observer hears will change base on the illustration above.

Before being engulfed, matter that is pulled into a black hole should become very hot and emit _____.
miss Akunina [59]
A black hole is a cosmological object that is created when a massive star comes to the end of its life and collapses under its own gravity. Black holes have massive gravitational fields  that even light cannot escape beyond a certain distance. Before being engulfed, matter that is pulled into a black hole should become very hot and emit electromagnetic radiation.
