A water droplet falling in the atmosphere is spherical. Assume that as the droplet passes through a cloud, it acquires mass at a rate equal to kA where k is constant(>0) and A its cross-sectional area. Consider a droplet of initial radius r0 that enters a cloud with a velocity v0. Assume no resistive force show that the radius increases linearly with time, and if r0 is negligibly small then the speed increases linearly with the time withing the cloud.
A water droplet of radius 0.018 mm remains stationary in the air. If the downward-directed electric field of the Earth is 150 N/C, how many excess electron charges must the water droplet have?
A water droplet of radius 0.024 mm remains stationary in the air. If the downward-directed electric field of the Earth is 150 N/C, how many excess electron charges must the water droplet have?
If you look into a 5 mm droplet of water in air, you can see images of objects behind the droplet. What will the magnification of an object 1 m behind the droplet be?
When a spherical droplet of liquid is sheared into much finer droplets, which of the following statement is correct for the final droplets? please explain your answer a. The sum of the radii of all the droplets will be equal to the radius of the initial droplet b. The mass of a single final droplet is same as that the initial droplet c. The sum of the volume of all the final droplets is same as that of the initial...
A uniformly charged spherical droplet of mercury has electric potential Vbig throughout the droplet. The droplet then breaks into n identical spherical droplets, each of which has electric potential Vsmall throughout its volume. The n small droplets are far enough apart from one another that they do not interact significantly. Find Vbig/Vsmall, the ratio of Vbig, the electric potential throughout the initial drop, to Vsmall, the electric potential throughout one of the smaller drops. The ratio should be dimensionless and...
Determine the pressure difference between the inside and outside of a i) water droplet, ii) soap bubble each with a 3-mm radius. Assume σ of soap to be same as pure water.
A spherical capacitor contains a solid spherical conductor of radius 1 mm, surrounded by a dielectric material with &r 2.0 out to a radius of 2 mm, then an outer thin spherical conducting shell. Determine the capacitance of the spherical capacitor. (Hint: Suppose you place a charge Q on the inner conductor and a charge -0 on the outer conductor Determine the electric field in the dielectric region between the conductors, then integrate SE .dr to determine the vollage difference...
