A famous celebrity has an extreme security system for their estate. the security system includes sensors in the ground as well as on the sides of the building. a loud truck drives down the road entering the estate. there is a sensor in the ground and another on the side of the security guards shed. if both sensors are 100m from the truck , which sensor will pick up the noise of the truck first and why?
a. guard shed- the sensor on the security guards shed will detect the sound first because the sound is traveling through the air sound will travel fastest through a gas
b. ground- the sensor in the ground will detect the sound first because the sound is traveling through the dirt and sound will travel fastest through solid.
c. same time- because the sound traveling through both the ground and the air at the same time, it will reach both the shed and the ground sensor at the same time.
d. neither sensor- 100m is too far for the sound to travel. neither sensor will pick up the sound of the truck until it is close to them
