If the total momentum of the insects is zero, this means all of the insects are at rest or are moving in opposite of each other. Same if the total kinetic energy is zero.
<h3>What is momentum? </h3>
Momentum is the quantity of motion which is multiplied by the amount of matter moved i.e., mass and the velocity at which it moves. Because, the object is in motion, it is a vector quantity, it has both direction and magnitude. It is determined by the product of the object's mass and the velocity of object.
If the total momentum of the insects is zero, this could mean anything of the two things. Either, all of the insects are at rest or an equal amount of insects are moving in opposite direction of each other which cancels out the total momentum of the insects.
If the total kinetic energy of the insects is zero, this means either all of the insects are at rest or an equal amount of insects are moving in opposite direction of one another which results into canceling out the energy.

Speed of wave = wavelength * frequency
Therefore, wavelength is 2.0 x 10^-8
Answer:
Magnets are employed to generate electricity.
Explanation:
Magnets' characteristics are employed to generate electricity. Electrons are pulled and pushed by moving magnetic fields. When you move a magnet around a coil of wire, or a coil of wire around a magnet, the electrons in the wire are pushed out and an electrical current is created.
Answer:
Because on different surfaces there's more/less friction. Smooth surfaces will allow the duster to accelerate while rough surfaces will decrease the acceleration.
Answer:
Explanation:
Given
Temperature of Hot reservoir 
Temperature of Cold reservoir 
Heat reservoir 
Work done 
heat Exhaust 
L.H.S=R.H.S
thus it follows first law
Cycle Efficiency
Carnot efficiency is less than cycle thus it violates second law
