Answer:

Total displacement 155 m

Explanation:

From the question, the formula to apply will be that of cosine rule where:

c=\sqrt{a^2+b^2-2ab*cosC}

where

a= 43 m , b=130m and c =? , <C=28° + 90° =118°

Substituting values in the equation as;

c=\sqrt{43^2+130^2-2*43*130*cos118}

c=\sqrt{1849+16900-11180*-0.46947} \\\\c=\sqrt{1849+16900+5249} \\\\c=\sqrt{23998} \\\\\\c=155m

Answer:

2.76×10⁻¹⁰ C

Explanation:

Applying,

V = W/q................... Equation 1

Where V = Electric Potential, E = Electric potential energy, q = charge.

make q the subject of the equation

q = W/V................ Equation 2

From the question,

Given: W = 4.26×10⁻⁸ J, V = 154.5 V

Substitute these values into equation 2

q = 4.26×10⁻⁸/154.5

q = 2.76×10⁻¹⁰ C
