Answer:

(i) 208 cm from the pivot

(ii) Move further from the pivot

Explanation:

(i) Sum of the moments about the pivot of the seesaw is zero.

∑τ = Iα

(50 kg) (10 N/kg) (2.5 m) + (60 kg) (10 N/kg) x = 0

1250 Nm + 600 N x = 0

x = -2.08 m

Kenny should sit 208 cm on the other side of the pivot.

(ii) To increase the torque, Kenny should move away from the pivot.

The strength of an electric field depends on the
KengaRu [80]
<span>The correct option is D) both A and B. In fact, the strength of an electric field produced by a single point charge is given by
</span>E=k  \frac{Q}{r^2}<span>
where Q is the charge that generates the field, k is the Coulomb's constante and r is the distance from the charge source of the field.

From the equation, we see that the strength of the field depends on A) the amount of charge that produced the field (Q) and B) the distance from the charge (r), so the correct option is D.</span>
