A steady DC current is flowing through a coil with an inductance of 248mH. The stored energy in the magnetic field is 431J. By how much does the current have to be increased, if the stored energy should be increased by 300J? All options given in Amps
- A.
17.824
- B.
76.78
- C.
17.82
- D.
17.822
- E.
76.77
- F.
76.87
Correct Answer
A. 17.824Explanation
The stored energy in a magnetic field is given by the formula E = 1/2 * L * I^2, where E is the energy, L is the inductance, and I is the current. In this case, the initial energy is 431J and the initial current is unknown. We can rearrange the formula to solve for the initial current: I = sqrt(2E/L). Plugging in the values, we get I = sqrt(2*431J/248mH). Solving this equation gives us the initial current as approximately 17.824 Amps. To increase the stored energy by 300J, we need to find the new current. Plugging in the new energy value of 731J into the formula, we get I = sqrt(2*731J/248mH), which gives us the new current as approximately 22.076 Amps. Therefore, the current needs to be increased by approximately 4.252 Amps.Rate this question:

What is the peak voltage value of a single-phase sinusoidal 600V AC RMS signal?
- A.
832.74
- B.
848.53
- C.
858.23
- D.
838.91
Correct Answer
B. 848.53Explanation
The peak voltage value of a single-phase sinusoidal AC signal can be calculated by multiplying the RMS value by the square root of 2. In this case, the RMS value is 600V, so the peak voltage value would be 600V * √2 = 848.53V.Rate this question:

Opening the shutdown circuit must occur if the implausibility is persistent for more than ___ ms.
Correct Answer
500Explanation
If the implausibility persists for more than 500 ms, it is necessary to open the shutdown circuit. This means that if the issue or problem continues for longer than half a second, the shutdown circuit needs to be activated to prevent further damage or malfunction. This is likely a safety mechanism to protect the system from any potential harm that may occur if the implausibility persists for an extended period of time.Rate this question:

There are two aircraft made in the year 1920 the propeller of aircraft 1 is rotating in an anti-clockwise direction while the propeller of the other rotates in a clockwise direction. The aircraft takes right turn to what will happen to aircraft 1 and 2.
- A.
1 and 2 both will move up
- B.
1 will move up while 2 will move down
- C.
1 will move down while 2 will move up
- D.
1 and 2 both will move down
Correct Answer
B. 1 will move up while 2 will move downExplanation
Since the propeller of aircraft 1 is rotating in an anti-clockwise direction, it will create a force that pushes the aircraft upwards. On the other hand, the propeller of aircraft 2 is rotating in a clockwise direction, which will create a force that pushes the aircraft downwards. Therefore, aircraft 1 will move up while aircraft 2 will move down.Rate this question:

A solid sphere of mass m and radius r is resting on a horizontal surface.A horizontal impulse of E is applied at a height h from the ground. Find the value of h so that sphere performs pure rolling motion after it has been struck.
Correct Answer
7r/5Explanation
To achieve pure rolling motion, the sphere must have both translational and rotational motion simultaneously. This means that the impulse applied at height h must provide enough torque to overcome the initial angular momentum of the sphere. The angular momentum depends on the moment of inertia, which for a solid sphere is (2/5)mr^2, and the angular velocity. Since the sphere is at rest initially, the angular velocity is zero. By applying the impulse at a height of 7r/5, the torque produced will be sufficient to set the sphere into pure rolling motion, with no slipping.Rate this question:

- A.
Yes
- B.
No
- C.
Maybe
- D.
Can't say
Correct Answer
B. NoExplanation
The addition of an extra member from the main hoop to the front hoop above the side impact structure suggests that the chassis has been modified. However, the fact that Percy is the shortest driver of the team implies that the modification may not be suitable for all drivers. Therefore, it is likely that the chassis will not pass TI (Technical Inspection) as it may not meet the necessary safety requirements for all drivers.Rate this question:

- D.
1-Interference, 2-Interference, 3-Line on line
- E.
1-Loose, 2-Loose, 3-Line on line
Correct Answer
D. 1-Interference, 2-Interference, 3-Line on lineExplanation
When fitting a ball bearing into a bore, an interference fit is required to ensure a tight and secure connection. Similarly, when fitting a tire on a rim, an interference fit is necessary to prevent the tire from slipping off. However, when fitting lugnuts on studs, a line on line fit is preferred as it allows for easy installation and removal of the lugnuts without compromising the stability of the connection.Rate this question:
