Alarge fish and a small cat stare at each other from either side of a flat vertical aquarium is20㎝ long from nose (closest to the glass) to tail (farthest from the glass), and each has its . face-offi wall. each nose 10 cm from the glass. a) to the fish, how far does the cat's nose look to be from the glass? b) to the cat, how far does the fish's nose look to be from the glass? c) to the fish, how long does the cat look? d) to the cat, how long does the fish look? the glass is thin enough to be ignored; you can "where" a point appea refract, and then trace back to where the refracted rays seem to be diverging from treat this as an air/water interface. hint: to determine rs to be, you must trace multiple rays emanating out from it, figure out how they

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
