Answer:proton as they bear positive charge and located at the nucleus
Answer:
33.0 m
Explanation:
We are given that
Wavelength,
Diameter of pupil=d=5.1 mm=
By Rayleigh criteria
Substitute the values
(if it's frictionless the length doesn't even matter :) )
It would have the same kinetic energy down as the potential energy up. That is,
or
(the mass doesn't even matter). The result is
, so only the height matters really. It is almost 9 (it is
).
Answer:
The pressure at Mombasa is 101.396 KPascal.
Explanation:
Given: Reading on barometer = 760 mm
= 0.76 m
Density of mercury = 1.36 x kg/
In this case, the pressure can be expressed as:
P = σhg
Where: σ is the density of mercury, h is height of mercury in the barometer, and g is the acceleration due of gravity.
But, g = 9.81 m/
So that,
P = 1.36 x x 0.76 x 9.81
= 101396.16 Pascal
P = 101.395 KPascal
The pressure at Mombasa is 101.396 KPascal.
