A balloon with the initial speed 5 m/s drops a bomb. When it reaches the ground, it explodes and the sound comes to the height of the balloon, which continues rising, for 15 sec. Find the height from which the bomb was dropped.

  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

float.

denser than water sinks in water.

denser than mercury would sink in it
