Answer:
1.092 cycles
Explanation:
We need to convert the arc length of 6.86 radians into cycles.
We know that,
1 radian = 0.1592 cycles
To convert 6.86 radians to cycles, we use unitary method.
6.86 radian = (0.1592 × 6.86) cycles
= 1.092 cycles
Hence, there are 1.092 cycles in 6.86 radians. Hence, this is the required solution.

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.

An object thats NEGATIVELY charged has more electrons than protons, An object thats POSITIVELY charged has less electrons than protons, An object that NOT charged has the same number of electrons and protons.
Answer:
10m/s
Explanation:
Using the law of conservation of momentums
M1u1+m2u2 = (m1+m2)v
Substitute.
4000(10)+1500(10) = (4000+1500)v
40,000+15,000 = 5,500v
55000 = 5500v
v = 55000/5500
v= 10m/s
Hence the velocity of the truck after Collision is 10m/s
