The basic SI unit that has anything to do with electricity is the unit
of electric charge ... the Coulomb.
Every other unit connected with electricity is a combination of the
Coulomb and the other basic SI units ...kilogram for mass, the meter
for length, and the second for time.

<em>Hi there !</em>
<em>Gold is a metal with a very high density.</em>
<em>The density of gold is higher than that of lead.</em>
<em>Density(gold) = 19300 kg/m³ = 19.3 g/cm³</em>
<em />
<em>19.3 g ............ 1 cm³</em>
<em>5 g ..................x cm³</em>
<em>x = 5g×1cm³/19.3g = 0.2590 cm³ ≈ 0.26 cm³</em>
<em>Good luck ! </em>

Answer:</h2>
Workdone = 601.33 Nm
<h2>
Explanation:</h2>
Workdone = Force(F) x horizontal distance(d).
Wordone = F x d
Where F is the horizontal component of the force
Force = 35 pounds
Recall that;
1 pound force = 4.4N
=> 35 pounds = 35 x 4.4N = 154N
=> Force = 154N
But since the rope makes a 10⁰ angle with the ground,
The horizontal component of the force F is Force x cos10⁰
=> F = 154 cos 10⁰
=> F = 154 x 0.9848
=> F = 151.66N
Horizontal distance (d) = 13 feet
Recall that;
1 foot = 0.305m
=> 13 feet = 13 x 0.305m = 3.965m
=> d = 3.965m
=> Substituting the values of F and d into the equation above, we have;
Workdone = F x d
Workdone = 151.66N x 3.965m
Workdone = 601.33Nm
