Correct answer choice is:
C. Be in phase with each other.
Explanation:
Components waves mix to produce a resultant with the equivalent wavelength but the amplitude which is bigger than the amplitude of both of the unique component waves, and this results in constructive interference, which states that the interference of two or more waves of identical frequency and phase, constructing in their respective reinforcement and constructing a single amplitude equivalent to the total of the amplitudes of the unique waves.
B. T=273K and P=0.25 atm
C. T=300k and P=2 atm
D. T=273K and P=2 atm​

C. They break down when reacting with acids
D. They can be altered with and electric current
Answer:
B
Explanation:
They are the BASE elements. Cannot make them any simpler.
Answer: Projectiles travel with a parabolic trajectory due to the influence of gravity. There are no horizontal forces acting upon projectiles and thus no horizontal acceleration, The horizontal velocity of a projectile is constant (a never changing in value.

The correct answer of this question is : From high potential to low potential.
EXPLANATION :
Before going to answer this question, first we have to understand the conventional rule for current flow.
As per the conventional rule of electricity, the current direction is opposite to the direction of electronic motion.
The current flows through a conductor is due to the motion of the free electrons. When the conductor or wire is attached to any electric source, the electrons are drifted towards the positive terminal of the source. Hence, electrons are moving from negative terminal to positive terminal.
As per the conventional rule, the current direction will be from positive terminal towards negative terminal i.e from higher potential to lower potential.
Hence, the correct answer of this question is from higher potential to lower potential .
B. Sample A would be best, because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the largest.
C. Sample C would be best, because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the smallest.
D. Sample C would be best, because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the largest.
Answer: Option C: Sample C would be best, because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the smallest.
Explanation:
The absorption coefficient of the samples is given. Sample A has 30%, Sample B has 47% and Sample C has 62%. This means that sample C absorbs the most percentage of energy incident on it. The energy in the reflected wave would be least. Hence, it would be best to use for a room to make it soundproof.
The correct answer is Option C) Sample C would be best, because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the smallest.
As the coefficient of absorption would define the energy present in the reflected wave, the material C has the highest percentage of absorption i.e. 62% and would be best suitable to make a sound proof room.
