6. The fire-security system of the buildings will be activated if the internal temperature passes 140 [°F]. The siren will make a sound with frequency 915 [Hz]. What will be the frequency of the sound heard by the observer who moves toward the building with the speed 5 [m/s]. The average speed of the sound in the air: 340 [m/s]. Round the result to the nearest tenth.

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

overcharge is the right answer system

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

the answer is 12 as i may remember
