Explanation: Just did the assignment on ED.
The term best describes why the windows vibrate when a car with loud bass speakers drives by a house is Resonance.
Resonance is a system's or object's relatively strong selective response to an outside oscillatory force that causes it to vibrate in step or phase. The vibration that is caused in a violin or piano string of a specific pitch when a musical note of the same pitch is sung or performed nearby is an example of acoustical resonance.
Resonance is the word that best describes the cause of the windows' vibration. It occurs when a vibrating system or outside stimulus causes another system to oscillate more violently and at a certain preferred frequency. Because of this, the house's windows vibrate a lot. On the nuclear scale, a type of resonance that resembles a particular kind of mechanical resonance has been discovered.
Therefore, the term best describes why the windows vibrate when a car with loud bass speakers drives by a house is Resonance.

The term that best describes why the windows vibrate is resonance. It is described when a vibrating system or external force drives another system to oscillate with greater amplitude at a specific preferential frequency. That is why the windows of the house vibrate significantly.
B) Image B
C) Image C
D) Image D
Answer:
Image B represents the force on a positively charged particle caused by an approaching magnet.
Explanation:
The most fundamental law of magnetism is that like shafts repulse each other and dissimilar to posts pull in one another; this can without much of a stretch be seen by endeavoring to put like posts of two magnets together. Further attractive impacts additionally exist. On the off chance that a bar magnet is cut into two pieces, the pieces become singular magnets with inverse shafts. Also, pounding, warming or winding of the magnets can demagnetize them, on the grounds that such dealing with separates the direct game plan of the particles. A last law of magnetism alludes to maintenance; a long bar magnet will hold its magnetism longer than a short bar magnet. The domain theory of magnetism expresses that every single enormous magnet involve littler attractive districts, or domains. The attractive character of domains originates from the nearness of significantly littler units, called dipoles. Iotas are masterminded in such a manner in many materials that the attractive direction of one electron counteracts the direction of another; in any case, ferromagnetic substances, for example, iron are unique. The nuclear cosmetics of these substances is with the end goal that littler gatherings of particles unite as one into zones called domains; in these, all the electrons have the equivalent attractive direction.
A positively charged particle will be deflected by the magnetic force when it approaches a magnet. Look for an image in which the particle's path deviates away from the magnet. Without the images, a specific selection cannot be made.
The question relates to the force exerted by a magnet on a positively charged particle. A magnet has two poles, North and South. A positively charged particle moving towards a magnet will be deflected by the field, with the direction of deflection dependent on the specific pole it is approaching. Without the images being provided, it's hard to give a definite answer. However, you should look for an image where the particle's path deviates away from the magnet, as this represents the magnetic force applied to it.

Acceleration = (change in speed) / (time for the change)
Change in speed = (speed at the end) - (speed at the beginning)
Change in speed = (54 km/hr) - (32 km/hr) = 22 km/hr
Acceleration = (22 km/hr) divided by (the time it takes to change the speed)
