2. How long will it take to discharge C1 below 60V using the following constant current sink if it is initially charged at 565V? (MOSFET’s VGSth: 4V) Give answer to two decimal places in secs.

Circuit’s current: MOSFET will operate in linear zone, close to the activation voltage. Therefore, as VGSth is 4V, VS can be taken as 8V. From these 8V and the 47R current limiting resistor, the discharge current of the circuit will be 8/47->0,17A
As the constant current discharge of a capacitor depends on capacity, as V=i·t/C->

6. A thin circular, isolated wire made of copper with radius R lies on a table with its ends
connected to a Volt meter. Another, straight wire lies exactly along a diameter of the
circular wire, connected to an alternate current source i(t) = I0 sin(wt).
The experimental setup is shown in the following Figure:

Which effective voltage Ueff does the Volt meter display?
R = 10 cm, maximum current I0 = 1 A, f = 50 Hz.
Give your answer in Volts with three decimal places

The magnetic field lines H around the straight, current-carrying wire run in concentric circles, with their centres lying on the wire axis. The field lines thus enter the wire perpendicularly in one half of the circle and leave it perpendicularly in the opposite half. This means that one semicircle of the induction loop is penetrated by the time-varying magnetic flux (t), while the opposite semicircle is penetrated by exactly the opposite flux -(t) for reasons of symmetry. The total flux at any time is zero at all times, which means that no induction voltage and thus no effective voltage Ueff is indicated at any time. The specification of the data in the task was therefore completely superfluous.

3. An object is fired vertically upwards from the ground at time t = 0 s in still air at a speed of 8.0 m/s. On the way up, what is the height of the object above the ground when it has a speed of 2.0 m/s. At what time does it reach this height on the way down? Give both answers separated by a comma to one decimal place.

Possible solution:

use this formula to calculate the required height: „v^2 = u^2 + 2as“ -> 3.1m
use same formula again to calculate the maximum height the object reaches -> 3.3m
then use this formula to calculate the time the object takes to reach maximum: „v=u + at“ -> 0.8s
calculate the time taken for the object to fall from the maximum height to 3.1m (first answer): „s =2at^2“-> 0.2s
add together the two calculated times -> 1.0s

4. You would like to drink a cup of very hot coffee with milk early in the morning, but you
are in a hurry and have only 5 minutes until you have to leave for work. At which time
after brewing should you add the cold milk to the coffee and stir in order to decrease the
temperature of the mixture as much as possible:
a) 0 minutes (immediately),
b) 2 minutes, or
c) 4 minutes?
Suppose that the stirring can be done instantaneously and that you need the last one
minute for drinking.

brew temperature C = 80 ◦C, temperature of milk = M = 10 ◦C, room temperature
0 = 20 ◦C, volume of coffee VC = 300 ml, volume of milk VM = 100 ml, specific heat
capacity of coffee cC = 4180 J/(kgK), specific heat capacity of milk cM = 3500 J/(kgK).

Please enter only the letter of the corresponding answer

a. 4 mins

b. 0 mins

c. 2 mins

The driving „force“ for the cooling of the coffee is the temperature difference between the warm coffee and the environment (room temperature), which leads to an exponential drop in coffee temperature. The temperature difference is greatest immediately after brewing. The later we stir in the milk, the lower the coffee temperature has already dropped. On the other hand, lowering the temperature by the milk becomes smaller the longer we wait.
So we let the coffee cool down on its own for as long as possible in order to bring about the temperature reduction by the cold milk at the end. The greatest possible cooling is therefore achieved when the milk is added after 4 minutes.
