Suppose the space between the plates of the capacitor is filled
with equal thickness of the same dielectrics but arranged as
shown in the figure. Each having an area of 8.0x10-4 m2 and
separated from each other by 5.0 mm. Half of the space between
the plates is filled with glass and the other with mica. What is its
capacitance?
A block moves along a horizontal surface with a 0.61 coefficient of kinetic friction. The block is pulled by a rope that exerts a 162 N tension force at 370 above the horizontal. Draw the FBD. Determine the kinetic friction.
At the surface of Jupiter’s moon Io the acceleration due to gravity is g=1.81 m/s2 . A watermelon weighs 44.0 N at the surface of the earth. a) What is the mass on the earth’s surface? b) What are its mass and weight on the surface of Io?
A market failure occurs when there is an inefficient allocation of resources. In other words, the true cost of a good is not reflected in the price. This might be because of a third-party benefit but does not pay for that benefit. Or, it could arise due to a cost that is imposed on a third party without their consent and compensation. In turn, this leads to an inefficient allocation of resources as a third party may bear the cost or benefit. There are many causes of market failure which range from externalities to inefficient supply. The inefficient allocation of resources is not just limited to the supply of goods. Market failure can also occur through externalities. This can be both positive and negative
Propose and analyze any four causes of market failure.
Over the last two decades, there has been an emphasis, particularly in the English-speaking advanced countries, on reducing the role of government and on reforming public management by adopting aspects of private sector practice. The research programme on which this study is based was concerned with the fact that similar practices were being introduced in developing and transitional countries, often in association with economic adjustment. There has been considerable research on the difficult process of adjustment but little on the process and outcomes of public management reform for improved service delivery.
question: Taking into consideration the theoretical knowledge you have gained on the broad views of the role of government, critically analyse the view South Africa’s government subscribes to in playing its role in the country. Justify your answer

There are many things that can address learner violence. Select three from the list below that the NSSF and Protocol can achieve.
The gravitational force between two identical spheres is given as 6 x 10-5 N. The spheres are separated by a distance of 0.60 m at the center. What is the mass of each sphere?
the mean score and the standard score in the statistics test are repectively equal to 80 and 2.5, whereas in the pre calculus test they are respectively equal to 70 and 2. if vince got a score of 85 in statistics and a score of 75 in pre-calculus, in which subject is her standing better assuming normality on both subject?
A 60W-100V tungsten lamp has a resistance of 20 ohms at air temperature (0◦C). What is the rise in temperature of the filament under normal working conditions? The temperature coefficient of resistance of tungsten is 0.0052/◦C.
