(b) you ride in a boat whose speed relative to the water is 8.2 m/s. if the river flows at
1.8 m/s, at what angle should the boat point in order that it arrives at a point directly
opposite, i. e., for the boat to move perpendicular to the shores of the river? [8]

The boat should point in angle to the perpendicular to the shore is, Ф = 12° 22'

Explanation:

Given data,

The velocity of the boat, V = 8.2 m/s

The velocity of the flow of the river, V' = 1.8 m/s

Let Ф formed by the boat perpendicular to the shore,

The two velocity components along the perpendicular axes are V and V'

Therefore,

                                  tan Ф = V' / V

                                             = 1.8 / 8.2

                                             = 0.2195

Therefore,

                                         Ф  = tan⁻¹ (0.2195)

                                              = 12° 22'

Hence, the boat should point in angle to the perpendicular to the shore is, Ф = 12° 22'

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.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
