The diameter of the reflecting surface of spherical mirror is called its aperture. Mirrors whose aperture is much smaller than its radius of curvature, we use R=2f.

Answer:
Explanation:
Voltage and current in resistors
A graph of current against potential difference shows you how the current flowing through a component varies with the potential difference across it. The current flowing through a resistor at a constant temperature is directly proportional to the potential difference across it.
Answer:
Joule is the answer
Please give me brainleast
v = u + at where v = final speed, u = initial speed , a = acceleration and t = time.
so here final speed v = 30 + 2*4 = 38 m/sec. answer
Distance travelled during this time
= (30 + 38) * 4 / 2 = 68 * 2 = 136 m answer
