A galvanic cellis applied by the combination of fe rodimmersed in feso4 solution of concentration 0.25M
Assume that the area that a pheromone can be sensed is a cylindrical air space. Calculate the volume of this air space assuming a radius of 0.500 mi and a height of 40.0 ft.
A galvanic cell is constructed by immersely of cu rod in cuno3 solution of 0.01M and ag rod in agno3 solution of 0.1M
The most powerful 5G antennas work with a power of 120W. Assume that the human head is a sphere with a radius of 10 cm and that the human body is made of water. For simplicity, you can also assume that the antenna transmits radio waves in all directions evenly.
a) Estimate the upper limit (worst case scenario) of how much energy is captured by the human head if we are standing just below the antenna (5 m from the antenna). Indicate which laws and concepts you used in the calculation.
b) Estimate how long it would take to stand under the antenna to warm the brain by 0.1 ° C if all cooling modes are neglected.
c) List and describe as many ways as possible in which the human brain dissipates heat to the environment.

Find the value of (x+Y)if x+Y=5 and x-Y=15
One-meter-long coaxial cable is incorrectly connected to the output device, so part of the signal bounces back on the connection. Determines the speed of the signal along the wire if we see echoes in the signal with a delay of 10 ns. Determines the wavelength of the signal in the cable if its frequency is 10 GHz.

IF YOU START WITH 50N G OF IRON III OXIDE,AND 25 G AL, WHAT IS THEMAXIMUM MASS OF ALUMINUM OXIDE THAT COULD BE PRODUCED? HOW MUCH AL OXIDE WOULDNBE PRODUCED IF HE YIELD IS 93%
A student performs an experiment to determine the density of a sugar solution. She obtains the following results: 1.27 g/mL, 1.29 g/mL, 1.28 g/mL, and 1.29 g/mL. If the actual value for the density of the sugar solution is 1.86 g/mL, which statement below best describes her results?
