If the energy of a wave increases, the amplitude of the wave increases.(1 point)
true or false
(if anyone else is doing this test please send answers ASAP)
False. The amplitude of a wave is not directly related to its energy. The amplitude of a wave refers to the maximum displacement of particles in a medium from their rest position as the wave passes through. The energy of a wave, on the other hand, is related to the intensity or power carried by the wave, which is determined by both the amplitude and frequency of the wave.
Analog signals are more reliable than digital signals because they are less likely to be affected by bad weather. (1 point)
True or False
(if anyone else is doing this test please send answers ASAP)
False. Digital signals are generally more reliable than analog signals because they are less susceptible to noise and interference. Bad weather can affect both analog and digital signals, but digital signals can be more easily corrected or regenerated due to error correction techniques.
Your Mom slams on her brakes in the car and your body keeps moving forward towards the windshield. This is called inertia and is an example of Newton’s 1st Law. (1 point)
True or False
(if anyone else is doing this test please send answers ASAP)
True. Inertia is the tendency of an object to resist changes in its motion. According to Newton's first law of motion, an object at rest will stay at rest, and an object in motion will stay in motion with the same velocity, unless acted upon by an external force. When your mom slams on the brakes and the car comes to a sudden stop, your body continues to move forward due to inertia until acted upon by the seatbelt or any other external force. This is an example of Newton's first law.

A. Objects with the same charge attract each other, and objects with opposite charges repel each other.
B. Objects with the same charge repel each other, and objects with opposite charges attract each other.
C. Objects with positive charges repel each other, and objects with negative charges attract each other.
D. Objects with positive charges attract each other, and objects with negative charges repel each other.
B. Objects with the same charge repel each other, and objects with opposite charges attract each other.
