Answer:
No, it cannot. The car needs the friction of the surface to drive because the car pushes the surface backwards, and the surfaces makes a reaction force pushing the car forward, and that works because of the friction. In a frictionless surface the tires would rotate in the same place
Answer:
The torque will be felt by the coil is zero
Explanation:
The torque is:
Where
μ is the magnetic moment = N * I * A, where N is the number of turns, I is the current and A is the area
A = 0.1 cm² = 1x10⁻⁵m²
If the angle between the area and the magnetic field is 0 (are in parallel), then:
Answer:
Definiton 1.the refusal to accept or comply with something; the attempt to prevent something by action or argument
Definition 2. the ability not to be affected by something, especially adversely
Definition 3. the impeding, slowing, or stopping effect exerted by one material thing on another
Definiton 4: the degree to which a substance or device opposes the passage of an electric current, causing energy dissipation. Ohm's law resistance (measured in ohms) is equal to the voltage divided by the current.

Answer:
Resistance = 400000 Ohms
Explanation:
Given the following data;
Voltage = 1200 V
Current = 3 mA = 3/1000 = 0.003 A
To find the resistance;
Voltage = current * resistance
Resistance = 1200/0.003
Resistance = 400000 Ohms
