To maximize the power delivered to load, we should minimize the internal resistance which means option A is correct.
<h3>What is the relationship between the power and the internal resistance?</h3>
Power can be delivered to the internal resistance of a battery, but in a case whereby there is a decrease in the internal resistance will bring about the decrease in the lost power as well as the increase in the percentage of the power delivered to the device.
In this case, To maximize the power delivered to load, we should minimize the internal resistance
Therefore, Option A is correct.

velocity = traveled distance ÷ time of the traveled distance is seconds
velocity = 600 ÷ 60
velocity = 10 m/s
_________________________________
Kinetic Energy = 1/2 × mass × ( velocity )^2
KE = 1/2 × 60 × ( 10 )^2
KE = 30 × 100
KE = 3000 j
Answer:
v(t) = s′(t) = −9sin(t)+9cos(t)
a(t) = v′(t) = −9cos(t) −9sin(t)
Explanation:
Given that
s = 9 cos(t) + 9 sin(t), t ≥ 0
Then acceleration and velocity is
v(t) = s′(t) = −9sin(t)+9cos(t)
a(t) = v′(t) = −9cos(t) −9sin(t)
