When a magnet is being pushed through a solenoid or when a magnet is being pulled out of a solenoid, a current would register on the galvanometer. The correct options among the three options that are given in the question are the first option and the third option. The magnet needs to be moved to generate the required current.
Answer:
Explanation:
U = 0.375 kg (1970 J/kg•°C)(145 - 103 °C) = 2,992.5 ≈ 2.99 kJ
Answer:
By induction method
Explanation:
Induction method involves charging an electrically neutral body by bringing it in contact with an electrically charged body.
For the electrophus, a charge opposite that on the slab is induced on the side in contact with the slab; driving the opposite charge (this will be the same as that on the slab) to the other end of the elctrophus. Touching the electrophus removes the charge opposite the charge induced on the electrophus by the charged slab either by drawing up charge from the earth or taking the charge to earth (depends on the charge. A negative charge is drawn to earth while a positive charge draws up electrons from the earth)
This is due to the law of inertia, an object at rest stays at rest and an object in motion stays in motion unless acted upon an unbalanced force.
So when you are traveling in a car I'm assuming the driver Gina is wearing her seatbelt, when Gina hits her brakes that is the "unbalanced force". By hitting the brakes Gina will also nudge forward but is stopped by her seatbelt from going too far forward. The teddy bear is not so lucky and since he's not wearing a seatbelt he is propelled forward hitting the dashboard. Poor Teddy.
Answer:
"*The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane.
*The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal.
*The reflected ray and the incident ray are on the opposite sides of the normal."
