During the first phase of acceleration we have:
v o = 4 m/s; t = 8 s; v = 13 m/s, a = ?
v = v o + a * t
13 m/s = 4 m / s + a * 8 s
a * 8 s = 9 m/s
a = 9 m/s : 8 s
a = 1.125 m/s²
The final speed:
v = ?; v o = 13 m/s; a = 1.125 m/s² ; t = 16 s
v = v o + a * t
v = 13 m/s + 1.125 m/s² * 16 s
v = 13 m/s + 18 m/s = 31 m/s
Answer:
0.000439077936334 m
Explanation:
q = Charge of electron = 
E = Electric field = 
= Permittivity of free space = 
d = Distance between plates = 2 cm (assumed)
m = Mass of electron = 
The beam consists of electrons which means it has negative charge this means the upper plates will be positive and the lower plate will be negative.
The direction is upper to lower lower plate.
= Permittivity of free space =
Electric flux is given by
The charge per unit area on the plates is
Deflection is given by
The deflection is 0.000439077936334 m
The correct answer for this question is this one:
<span>A snowstorm was predicted in Chicago. The possible upper air temperature, surface temperature, and air pressure of Chicago on that day. Normal atmospheric pressure is 29.9 inches of mercury. </span><em>I'm pretty sure the answer is 40 for upper air, 29 for surface temp, and 30 for air pressure. </em>Hope this helps answer your question and have a nice day ahead.
