Answer:
Speed,
Explanation:
Given that,
Distance covered by the electron, d = 32 cm = 0.32 m
Time, t = 2 ns
We need to find the speed of an electron. Speed is equal to distance covered divided by time. So,
So, the speed of the electron is .
Answer:
140dB
Explanation:
In this problem you will be using the decibel scale to analyze a small firecracker that emits 1200 of peak power
In order to find to find the peak intensity in dB we must first determine the intensity in W/m^2 that the firecracker is producing:
I= P/(4π)
I= 1200/(4π ) =>96W/m^2
now the intensity in decibels can be calculated by using the dB conversion equation
β= 10log ( )dB
is a reference intensity in the above formula i.e for sound waves and its value is W/m^2
β=10log( )dB => 10log(9.6x )dB
β= 140dB
therefore, at a distance of 1 m from the firecracker the peak intensity β is 140dB
21 because if 1 has to be more than 5 and ur going 3 hours and multiple it it's 21.
