Answer: The correct answer is option (C).
Explanation:
Law of reflection:
- Angle of incident is equal to angle of reflection;∠i=∠r
- Incident ray, reflected ray and normal to the reflecting interface at the point of incidence all lie in same plane.
When light ray from candle strikes a mirror at an angle of 40° with the normal, then the angle at which ray reflected back will 40°.
C = Q/V, and since C is a constant, if voltage is doubled, charged will be doubled as well. Therefore charge will be 2Q
El peso anywhere = (mass) x (gravity there). Gravity en la Tierra = 9.81 m/s^2. Gravity en la Luna = 1.62 m/s^2.
