Answer: (Next time put the Image but I know what u talkin bout)
wave changes its path from its initial direction so this phenomenon is known as Refraction of wave
Explanation:
When wave travels from one medium to other medium the due to change in the speed of the wave propagation it deviates from its initial path.
The deviation of the wave from its initial path is known as refraction of wave
Here we can see that wave incident on medium 1 with some angle with the boundary
Then it enters into other medium and then travels in other direction
So here wave changes its path from its initial direction so this phenomenon is known as Refraction of wave
Answer:

Explanation:
The speed of the 0.5 kg block just before the collision is found by the Principle of Energy Conservation:





Knowing that collision is inelastic, the speed just after the collision is determined with the help of the Principle of Momentum Conservation:


Lastly, the height reached by the two blocks is:





Answer:
Temperature of the object
Explanation:
According to kinetic theorem of gases, the temperature of a gas is a measure of the of the average kinetic energy of the gas particle.
A particle can either exist as solid, liquid or gas.
For solid, the particles are fixed as they rotates and vibrate about a mean position.
The particle of an object is a solid particle.
In accordance to kinetic theorem, the temperature of an object related to the average kinetic energy of the particles in the object.\
Temperature: This can be defined as the degree of hotness or coldness of an object.
Answer:
0.1 m
Explanation:
The closest distance the electrodes used in an NCV test in oerder to measure
the voltage change as a response to the stimulus is 0.1 m.
This is because the shortest observable time period is not less than the action-potential time response of 1 mili second the length traveled by the sensation during this time is 1 m sec x 100 m / s =0.1 m, which is the shortest distance the electrodes could be positioned on the nerve.
