Energetic particles, such as protons, can be detected with a silicon detector. when a particle strikes a thin piece of silicon, it creates a large number of free electrons by ionizing silicon atoms. the electrons flow to an electrode on the surface of the detector, and this current is then amplified and detected. in one experiment, each incident proton creates, on average, 37,000 electrons; the electron current is amplified by a factor of 100; and the experimenters record an amplified current of 3.5 μa.

the assestment will probley apele with cause and effect

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
