Answer:
c. Both Technicians
Explanation:
A steering wheel position sensor is being discussed. Technician A says that the sensor is used to determine the direction of the steering wheel. Technician B says that the sensor detects how fast the steering wheel is turned. the following are used to sense
Hall-effect, Photo cell, Potentiometer are used on vehicles equipped with an electronically controlled suspension
sensors are like indicators in a vehicle to give signals for both direction and the speed of the vehicle
c. Both Technicians
resistance. The total amount of heat energy
produced by the heater in 60.0 seconds is
(1) 7.20 × 10^3 J (3) 8.64 × 10^4 J
(2) 5.76 × 10^4 J (4) 6.91 × 10^6 J
Ohm's law :
V = IR
The amount of work done is
P = IV or P = I^2R (using Ohm's law to substitute)
Therefore,
P = 64*15
= 960W
So the total energy released is
Pt = 960*60
= 57600J
"Ohm's law states the relationship between electric current and potential difference. It states that the current that flows through most conductors is directly proportional to the voltage applied to it."
The strength of a direct current is directly proportional to the potential difference and inversely proportional to the resistance of the circuit.
Work done : W = (|F| cosθ) |d|
"Work done is defined as the multiplication of magnitude of displacement d and the component of the force that is in the direction of displacement."

B. because it has constant velocity
C. because its direction is changing
D. because the distance it is traveling is changing
A. Because it is going faster.
Electrons move from the atoms in the balloon to the atoms in the cloth, causing the cloth to have a negative charge.
B.
Everyday objects do not have electric charges, so neither the balloon nor the cloth can gain or lose electrons.
C.
Electrons move from the atoms in the cloth to the atoms in the balloon, causing the balloon to have a negative charge.
D.
Electrons are shared equally between the atoms of the balloon and the atoms of the cloth, making both electrically neutral.
