The focal point of a concave mirror is halfway along the radius, therefore the radius would be 2•16= 32 cm
A pure substance that cannot be decomposed by ordinary chemical change. . Energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means.
A line that is falling towards the x axis represents an object that is negatively accelerating, or slowing down. When the line hits the x axis, the object has stopped moving. If the graph continues below the x axis, the object has changed direction and is moving backwards at increasing velocity.
Answer:
The discharge of a capacitor changes the direction of the current
Explanation:
Capacitor is used to store charges. Changing and discharging a capacitor changes the direction of the current.
When a capacitor is charging, current flows towards the positive plate and away from the negative plate. When the capacitor is discharging, current flows away from the positive and flows towards the negative plate, in the opposite direction. During these two processes (charging and discharging), it can be seen that the direction of the current is changed.
Therefore, the discharge of a capacitor changes the direction of the current
