The safest option in the lab if one need your vision to be corrected is wear corrective glasses or lenses under your safety goggles for the whole experiment, but always check with your ta or instructor for your school's policy.
<h3>What are safety goggles?</h3>
When someone is performing any project in the chemistry lab, he needs to be extra care taken by himself and and the most importantly from the school. The safety goggles are used to protect the eyes from any spiling off the chemical.
One should wear corrective glasses under the safety goggles during the whole experiment.
Thus, wear corrective glasses under the safety goggles during the whole experiment.

Answer:
The correct option is b
Explanation:
From the question we are told that
The resistance of the first resistor is 
The resistance of the second resistor is 
The capacitive reactance of the first capacitor is 
The capacitive reactance of the first capacitor is 
Generally given that the resistors are connected in parallel , their equivalent resistance is
=> 
=> 
Generally given that the capacitors are connected in parallel , their equivalent capacitive reactance is
=> 
=> 
Hence the impedance of the circuit is
=> 
Generally from the impedance equation , the total used resistance is
Answer:
I would say that I agree with the one that said that each hill must be lower than the previous one and use the principle of conservation of energy to explain.
Explanation:
Roller coaster are usually designed such that its total energy remains conserved at any point on the track. Now, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. At certain height on the track, the total energy of the roller coaster is in form of potential energy, which gets converted to kinetic energy as soon as it starts sliding down the hill till get to the hill's endpoint where it has maximum kinetic energy. The cycle of sliding from a high point on the track to a low point on the track means there is potential energy is converted to kinetic energy and kinetic energy then converts back to potential energy and the cycle continues.
However, due to the effect of gravity and frictional force between the track and the coaster, the energy of the coaster is gradually reduces, so it becomes a bit difficult for the coaster to move to the next hill of the same height. It is for this reason that each hill must be lower than the previous one, so that the coaster can overcome the next hill's height with its reduced energy until it loses all its energy and comes to a stop.
Answer:
The displacements are not equal. While their direction is the same, their length (i.e., distance or magnitude) is not. A is longer than B.
