Alona [7]

Answer:

true about microscopic particle is that they can explain the phenomena of diffraction and interference.

Explanation

the first thing mentioned in question particles are localized in space according to classical physics particle can be well localized in space because its momentum and position can be determine simultaneously .second their properties can be measured and they can act like wave particle by particle build up a wave. so all of they things mention above only thing true about particles is that they describe the phenomena of diffraction and interference.

Why do you think glass bottles keep water cold longer?
Nina [5.8K]

Because glass is not a good heat conductor. What it means is that heat isn't transfered through its structure as quickly as it would with metal, for instance. Because heat can't penetrate glass as quickly, the contents stay at the same temperature for longer.

An ideal step-down transformer has a turns ratio of 1/106. An ac voltage of amplitude 170 V is applied to the primary. If the pr
Leya [2.2K]

Answer:

I_2=0.8586A

Explanation:

From the question we are told that:

Turns Ratio i.e\frac{N_2}{N_1}=\frac{1}{106} (step down)

Voltage v=170v

Primary current amplitudeI_1= 8.10 mA =>8.10*10^{-3}A

Generally the equation for a Transformer is mathematically given by

\frac{E_1}{E_2}=\frac{I_2}{I_1}=\frac{N_1}{N_2}

Therefore

I_2=\frac{N_1}{N_2}*I_1

I_2=106*8.10*10^{-3}

I_2=0.8586A
