1 Explain the difference between excess demand and excess supply (show using the graph)
60° = 50 m/s
There is an ongoing repair at Mrs. Trinket's house and a brass window of her house has dimensions of 15 cm by 12 in at 280C.
2x+5 < 7-8x
An ungranulated thermometer reads 2.0 and 12.9at ice andsteam point respectively.calculate the true temperature in kelvin when the thermometer reads 5.0
In the figure above, q1 = 6.53 nC, q2 = 13.1 nC, and q3 = 13.1 nC. If the net force on q1 is 0, then what would q be?
A knuckleball thrown with a different grip than that of the problem above has left/right
position as it crosses the plate given by
f(W) =
(0.625/w2)(1-sin (2.72w+π/2))
Again, use graphical and tabular evidence to make a conjecture about the lim f(w) as w approaches 0 from the right.
The capacitance of a parallel plate air capacitor is 350.0mF. When a sheet of a dielectric is inserted between the plates, the capacitance increases to 2100.0mF. What is the permittivity of the dielectric?
The Earth may be considered to be a uniform sphere of radius 6.38 × 106 m. Its mass is assumed to be concentrated at its centre.
Given that the gravitational field strength at the Earth’s surface is 9.81 N kg–1, show that the mass of the Earth is 5.99 × 1024 kg.
Methylhydrazine (N2H3CH3) is a common liquid propellant used in rocket fuels. Look for the standard molar enthalpies of formation of the reactants and products. Calculate the ∆Ho for the reaction.
(4)N2H3CH3 (l) + (5)N2O4 (l) ---> (12)H2O (g) + (9)N2 (g) + (4)CO2 (g)
