A kite is flying 100 ft off the ground, and its string is pulled taut. The angle of elevation of the kite is 55 degree. Find the length of the string. Round your answer to the nearest tenth.

Length of the string is 122 feet approx.

Given that;

Height of kite = 100 feet

Angle of elevation = 55°

Find:

Length of the string

Computation:

Sinθ = Perpendicular / Hypotenuse

Sin55 = 100 / Hypotenuse

0.8191 = 100 / Hypotenuse

Hypotenuse = 122 feet (Approx.)

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

Ibelieve the answer is d. densityhope my answer has you : )
