Answer:
a = 1.72 m/s²
Explanation:
The given kinematic equation is the 2nd equation of motion. The equation is as follows:
xf = xi + (Vi)(t) + (1/2)(a)t²
where,
xf = the final position = 5000 m
xi = the initial position = 1000 m
Vi = the initial velocity = 15 m/s
t = the time taken = 60 s
a = acceleration = ?
Therefore,
5000 m = 1000 m + (15 m/s)(60 s) + (1/2)(a)(60 s)²
5000 m = 1000 m + 900 m + a(1800 s²)
5000 m = 1900 m + a(1800 s²)
5000 m - 1900 m = a(1800 s²)
a(1800 s²) = 3100 m
a = 3100 m/1800 s²
<u>a = 1.72 m/s²</u>
In the context of the loop and junction rules for electrical circuits, a junction is where three or more wires are joined.
Answer: Option 2
<u>Explanation:
</u>
An electrical circuits consists of many points like branch, loop, junction, series, bridge, etc. So, loops are the ones where the output of one circuit will act as feedback of the same circuit. If two or more wires passes through a single point, then that point is termed as junction.
If two or three junction connect each other they are termed as branch. Like these several other parameters are there with different rules in the circuit system. For electrical circuits, junction and loop rules state that a junction is the point where more wires joined together.

Answer:
Current = 6.82 A
Explanation:
Given the following data;
Power = 1500 Watts.
Voltage = 220 Volts.
To find the current;
Power = current * voltage
Substituting into the equation, we have;
1500 = current * 220
Current = 1500/220
Current = 6.82 Amperes.
Therefore, the current that traverses it is 6.82 Amperes.
