3.2 Show your calculation and explain how base 60 number system is used to subtract 48 minutes from 2 hour 13 minutes?
The heat of dissolution of a solid substance was determined using an insulated calorimeter containing 180 grams of water initially at 27.8°C. If the temperature of the water increased to 36.5°C, what is the heat (in J) of dissolution of the solid?
suppose that during any hour in a large department store, the average number of shoppers is 448, with a standard deviation of 21 shoppers. what is the probability that a random sample of 49 different shopping hours will yield a sample mean between 441 and 446 shoppers?
You have a RC circuit which contains a capacitor of 0.02 F and a resistor of 350 Ohm. Calculate how
long it would take (in seconds) for the capacitor to be charged to 89% of its full voltage.
The weights (in kg) of 11 Stem B follow a normal distribution and has a mean of 52 and a standard deviation of 4. How many students have weights greater than 56?
Four forces act on an object such that the object is at rest. Three of the forces are given by F₁ = 21-2j, F₂=i-4j, F4 = −3i-5j. Determine F3 and its magnitude.
