a. What is the net electric flux through the surface is it encloses a net charge of 3.60μC?
b. The electric flux through a closed surface is found to be 7.80Nm2
/C. What quantity
of charge is closed by the surface?
Define the radiative heat transfer and how it maintains balance in the environment,
assuming the earth surface behaves as a black body materials
A disk of radius 1.20cm. It has a charged of -6.0nC spread uniformly over the said
disk. Find the magnitude and direction of the electric field this disk produces at point A on
the axis of the disk a distance of 2.0cm from its center
A 10.0cm long thin glass rod is uniformly charged to +50.0nC. A small bead, charged
-5.0nC is 4.0cm from the center of the rod. What is the force (both magnitude and direction)
on the bead?
Three charges lie along the x-axis. The positive charge q1 = 15.0μC is at x = 2.00m and
the positive charge q2 = 6.00μC is at the origin. Where must a negative charge q3 be placed on
the x-axis such that the resultant force on it is zero?
Calculate the solar angle for the day at 10am and 2pm individually for the location of
21.23 south latitude on the 18th march 1993 (Assume it is non leap year)
The central deflection of the diaphragm of an elastic type pressure measuring instrument was
found to be 0.25mm of an applied pressure of 106𝑝𝑎. The output displacement of diaphragm
has been fed to a Linear variable differential transducer (LVDT) with a built in amplifier
having a sensitivity of 40V/mm. Finally the output is displayed on an analog voltmeter which
has a radius of scale line as 60mm and has a voltage range from zero to 10 volts in an arc of
1500. Using a well labelled diagram, determine the sensitivity of the given diaphragm gauge
in terms of mm/bar (1 bar=105𝑝𝑎).
A bicyclist encounters a series of hills.uphill speed is always V1 downward speed is always V2. The total distance he travelled is X.with uphill and down hill portions of equal length.what was the cyclist average speed?
A boy travelled 240km with constant speed except for 30min cokkee break after he has been on the road for 1.5hr .the trip including the break takes him 2hr and 30min.what was his average spped?
