Working of a Half wave rectifier
The diode is connected in series with the secondary of the transformer and the load resistance RL. The primary of the transformer is being connected to the ac supply mains. The ac voltage across the secondary winding changes polarities after every half cycle of the input wave.
Answer:
27.1 m/s
Explanation:
Given that at a race car driving event, a staff member notices that the skid marks left by the race car are 9.06 m long. The very experienced staff member knows that the deceleration of a car when skidding is -40.52 m/s2.
Using third equation of motion,
V^2 = U^2 + 2aS
Since the car is decelerating, the final velocity V = 0
Substitute all the parameter into the equation above,
0 = U^2 - 2 * 40.52 * 9.06
U^2 = 734.22
U = 
U = 27.096
U = 27.1 m/s approximately
Therefore, the staff member can estimate for the original speed of the race car to be 27.1 m/s if it came to a stop during the skid

1.Life science involves fields of discipline catering to living organisms such as we humans while physical science caters to non-living organisms.
2.Life science has more fields of discipline than physical science.
3.Physical science relies on laws and theories to explain concepts while life science relies on biological explanations and can also rely on theories.
Answer:d-All of the above
Explanation:
A resistor is a device used in electrical circuits that offers resistance to current flow.In automotive circuit commonly used resistor are
- Fixed value
- Stepped
- Variable
Fixed value:A fixed value electrical resistance is one whose value is resistance value is fixed and does not change in circuit.
Stepped resistance:Stepped resistor also called as tapped resistors provide two or more set resistor values. In a circuit, the various resistances are attached to different terminals. When the switch is shifted, different resistance values are put in the circuit.
Variable resistance:The variable resistor gives more control over the current flow by increasing the resistance. When the resistance of the variable resistor increases, the amount of current allowed to flow in the circuit decreases.
