Gravity is the force that pulls two objects together
The answer is the second choice (B)
EXPLANATION:
In a longitudinal wave the particle displacement is parallel to the direction of wave propagation. The animation at right shows a one-dimensional longitudinal plane wave propagating down a tube. The particles do not move down the tube with the wave; they simply oscillate back and forth about their individual equilibrium positions. Pick a single particle and watch its motion. The wave is seen as the motion of the compressed region (ie, it is a pressure wave), which moves from left to right.
The second animation at right shows the difference between the oscillatory motion of individual particles and the propagation of the wave through the medium. The animation also identifies the regions of compression and rarefaction.
Answer:
Explanation:
Hello,
In this case, we can consider the following chemical reaction for the oxidation of copper which only occurs at high temperatures:
In such a way, for 0.032 grams of copper, the following grams of copper (II) oxide (black product) are yielded:
Therefore, the percent yield is:
Best regards.
Explanation:
Electric conductors are the substances which allow easy passage of electric charges from one atom to another in the presence of a certain amount of voltage.
A conductor in which electric charge passes easily is known as a good conductor. Whereas a conductor in which electric charge passes with difficulty or no electric charge passes through is known as bad conductor.
For example, copper is good conductor of heat and electricity as it conducts flow of current quite easily.
