There are two types of collision in physics which are named as elastic collision and inelastic collision.
Elastic collision is that type of collision in which both kinetic energy and momentum is conserved i.e total kinetic energy and momentum before collision is equal to the total kinetic energy and momentum after collision.As kinetic energy is conserved here,so less or ideally no damage occurs to the colliding bodies.
Inelastic collision is that type of collision in which only momentum is conserved but not kinetic energy .After the collision the kinetic energy is lost in forms heat,sound ,light etc.
Normally any deformation and destruction is due to the inelastic collision which results in the loss of kinetic energy.
Hence the helicopters were destroyed and deformed due to inelastic collision.
Answer:
prerecorded magnetic tapes used for noncommercialplayback of sound on audio equipment.
Explanation:
study hard:)
In the absence of gravity, t<span>he rocks and debris
would never accrete into a planet. (B)
Also by the way, it wouldn't matter much, because
there wouldn't be a star to orbit around, AND orbits
wouldn't exist either.</span>
Answer:<span>Humid air is lighter, so it has lower pressure.
The reason is the molecules of water are H2O, whose molar mass is 18 g/mol.
These molecules displaces molecules of N2 and O2, whose molar masses are:
N2: 2*14g/mol = 28 g/mol, and
O2: 2*16g/mol = 32 g/mol.
Then molecules of 28g/mol and 32 g/mol are being replaced with molecules of 18g/mol, leading to a lower weight of the same volume of air, which results in lower pressure.

Answer:
Neither technician
Explanation:
Neither technician is correct.
two bulbs are connected in series one bulb burn out
If one bulb in the series burns out then the circuit will break.
In a series circuit same current passes each resistor.
so, both the technician is incorrect bulb B will not work and current will not increase in the other bulb.
