In an experiment designed to measure the speed of light, a laser is aimed at a mirror that is 47.0 km due north. A detector is placed 119 m due east of the laser. The mirror is to be aligned so that light from the laser reflects into the detector.(a) When properly aligned, what angle should the normal to the surface of the mirror make with due south?

The incidence angle is 0.145°.

Explanation:

Given that,

Distance due to east = 119 m

Distance due to north= 47.0 km

We need to calculate the incidence angle

Using formula of incidence angle

Where, y = distance due to north

x = distance due to east

Put the value into the formula

Hence, The incidence angle is 0.145°.

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
