Two railroad cars each of mass 6500 kg and traveling 83 kmh in opposite directions collide head-on and come to rest How much thermal energy is produced in this collision?

81km/h = 81 /3.6 m/s
=22.5m/s
K.E = 0.5 m v^2
= 0.5 * 6500 * (22.5)^2
= 1 645 312.5 J
For both cars
K.E = 2* 1 645 312.5
= 3 290 625
K.E = Thermal energy
= 3 290 625 J

How can sounds cancel each other out?
Because sounds are made up of waves of compressed and decompressed air, and when two waves meet that are exactly out of phase, or opposite each other, then the total sound produced is zero. See "sound cancellation" in the link below.
Is strontium produced by nuclear fusion?
No Strontium is produced by nuclear fission not fusion.

What is the gas produced when limestone reacts with acid?
When limestone reacts with acid, Carbon Dioxide is produced.
When is a standing wave produced?
When waves equal in wavelength and amplitude, but traveling in opposite directions, continuously interfere with each other.
When are standing waves produced?
Standing waves are also known as stationary waves. They are waves that remain in a constant position. This phenomenon can occur because the medium is moving in the opposite direction to the wave, or it can arise in a stationary medium as a result of interference between two waves traveling in opposite directions.
What is the net force produced by a thirty N force and a twenty N force if the two forces act in opposite directions?
Ten
What is the sentence of horrible?
The collision produced a horrible crashing sound.
How were large mountain ranges such as the Himalayas produced?
Large mountain ranges such as the Himalayas were produced through the collision of tectonic plates. In the case of the Himalayas, the Indian Plate collided with the Eurasian Plate, causing the crust to crumple and uplift, leading to the formation of the mountain range. The force of the collision continues to push the Himalayas higher each year.
How were large mountains ranges such as Himalayas produced?
collision of tectonic plates
What is the net force produced by a 15.4 newton force and a 9.2 newton force if both forces are in opposite directions?
The net force is 15.4-9.2=6.2 Newtons in the direction of the 15.4 force.
When one force acts a second force is produced that is and opposite to the original force.?
equal and opposite
Why is sound produced when it thunder's?
The sound comes from the collision of two clouds in the sky, which also produces lightening.
What kinda boundary was involved with the earthquake in New Zealand?
In New Zealand there is a transform boundary, where two tectonic plates slide past each other in opposite directions. The type of fault produced by this boundary is called a strike-slip fault.
