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.

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->
t=V·C/i=(565-60)·0,0012/0,17=3,56s

A vehicle with the mass 190kg, wheelbase 1,56m and tyre static radius 222mm is weighed. Scales measure 83kg (front) and 107kg (rear) when the car measured on the perfectly flat ground and the same values when the front axle is elevated by 0,85m. What is the car’s COG height? Give answer to the nearest whole number in mm

draw all forces working on car and create balanced equation.
Fb‘ * L*cosθ – Fg * |AC| = 0 (rotated around point at A)
|AC| = |AB| + |BC| = (h – r) * sinθ + a * cosθ
a = L * (Fb/Fg)
Final formula: h = (Fb‘- Fb)/Fg × L × cot(θ) + r

Fb‘ = m*g (at rear axle while front tyres are lifted)

Fb = m*g (at rear axle while car standing on ground)

Fg = m*g (at COG)

L = wheel base

sin(θ) = H/L

r= radius of tyre
