Answer: All learning occurs through interactions with the environment; The environment ... In the before conditioning phase, an unconditioned stimulus is paired with an ... In our example, the conditioned response would be feeling hungry when you heard ... reinforce the salivation response to make sure the behavior is well learned.
Answer:
Explanation:
At the time when the capacitor starts charging , current through will be maximum .
Current in the circuit = 10 / 100 = .1 A .
This is called displacement current Id = .1 A .
magnetic field between the plates will be due to this displacement current .
Magnetic field lines will be circular in shape.
If B be the magnetic field , we shall apply ampere's circuital law to find magnetic field due to displacement current at a distance of 5 cm from axis.
∫ B dl = μ₀ Id
B x 2π x .05 = 8.85 x 10⁻¹² x .1
B = 2.82 x 10⁻¹² T .
If we have a moving electric charge with the velocity v, then the magnetic field will produce a force F=q*v*B*sinθ where q is the charge, v is the velocity, B is the strength of the magnetic field and θ is the angle of the velocity and the magnetic field. The force will only change the direction of the charge, and it's magnitude will be the greatest when the velocity and the magnetic field are perpendicular to each other and no force will act on the charge if θ=0. If the velocity of the charge is 0, again there is no force on the charge. We can get the direction of the force with the right hand rule.
Actually, the speed of the earth is the same everywhere, taking the angular speed as the valid measure of the speed
Answer: A heat engine uses temperature differences which cause pressure changes to exert force on a moving part. A Carnot Process is a theoretical explanation of a process involving pressure and temperature changes during ,amongst other things, phase changes.
