Answer:
lightning conductors/rods protect buildings by intercepting lightning strikes that may hit these structures.
Air conditioners pass air over cold coils known as evaporator pipes
Explanation:
Lightning rods are made of highly conductive metal, and offer a path of least resistance for any lightning strikes and are connected to longer wires that ground the charge.
air conditioners use a chemical compound called a refrigerant. the most common refrigerant used is r-134a also know as 1,1,1,2-Tetrafluoroethane. cooling systems use the low boiling points of these refrigerants to constantly cool and compress the chemical to continually move heat from the inside of the system to an external area.
Well formation of metallic bond depends on free electrons.smaal sized atoms hold their electrons more firmly as compared to large size atoms ,this z due to distance of outer shell electrons by nucleus..in this way no of free electrons affect strength of metallic bond..smaal sized atoms release less free electrons..
Explanation:
ESTE PROBLEMA ES MEJOR HACERLO EN SI. PRIMERO CONVIERTES
LA VELOCIDAD INICIAL Y LA VELOCIDAD FINAL A m/s
= 33.52 m/s <em>v</em> = 53.67 m/s <em>x</em> = 3220 m
PRIMERO ENCUENTRAS LA ACELERACIÓN DEL COCHE CON LA ECUACIÓN
DE GALILEO GALILEI
<em>a</em> = =
AHORA CON LA ACELERACIÓN USMOS LA SEGUNDA LEY DE NEWTON
F = 75 kg() = 40.9 N
B. The object stops from a velocity of 12.0 m/s
Answer:
D. The frequency is not affected as the volume of sound increases
Explanation:
Volume of the sound is defined by the amplitude of the wave or how loud a sound is whereas Frequency is basically the pitch of the sound and is inversely proportional to the wavelength . Increasing frequency will increase the pitch of the sound without affecting it's volume.
