Answer:
Slightly above 20°c
Explanation:
The resistivity of silver is 1.59 x 10-8Ωm{ as discovered by experiment from scientist}
The resistivity of tungsten at 20°c is 5.6x10-8Ωm
We see the value is just an approximation of 4 times not exactly.
Light<span> refracts whenever it </span>travels<span> at an angle into a substance with a </span>different<span>refractive index (optical density). This change of direction is </span>caused<span> by a change in speed. For example, when </span>light travels<span> from air into water, it slows down, causing it to continue to travel at a </span>different<span> angle or direction.</span>
Here are the answers to the given question above.
<span>Relative dating uses laws or principles of stratigraphy and paleontology. These laws of relative dating are:
-</span><span>law of original horizontality
-</span><span>law of superposition
-</span><span>law of original lateral continuity
-</span><span>law of cross-cutting or intrusive relationships

Explanation:
1. Mass of an object
2. Distance between the objects
Answer:
FAE= 0.014 N
Explanation:
The KE of block is decreased because of the slowing action of the friction force .
Change in KE of block = work done on block by friction ƒ
⠀ ➪ ½mu²ƒ - ½mu²i = Fƒs cos θ
Because the friction force on the block is opposite in direction to the displacement , cos θ = -1
➢ Using Uƒ = 0 , Vƒ = 0.20 m/s , and s = 0.70 m
✒ We find ,
➪½mu²ƒ - ½mu²i = Fƒs cos θ
➪0-½ (0.50 kg) (0.20 m/s)² = (Fƒ) (0.70 m) (-1)
➪ Fƒ = 0.014 N
