Answer:
no, 3 porces is more tha 2 so the power between the 3 should be more than 2
Explanation:
D) Scientific laws do not account for unseen variations, like wind
Explanation:
Will model in predicting the path of an arrow he was about to shoot failed because scientific laws most times do not account for unseen variations like wind.
Scientific laws are the description of an observed phenomenon in nature.
- Most scientific laws have exceptions.
- Exceptions in scientific laws are conditions in which the law will not hold true.
- There are exceptions to newton's law of motion which Will did not take into account.

Resistance = (voltage) / (Current)
Resistance = (10 V) / (5 A)
Resistance = 2 ohms.
Answer:
1250 J
Explanation:
Work is said to be done when a force causes an object to move over a distance. The amount of work done (W) is calculated by multiplying the force by the distance traveled.
That is;
W = F × d
Where;
W = work done (J or N/m)
F = force (N)
d = distance (m)
Based on the information provided in this question, F = 5000N, d = 0.25m
Hence;
W = F × d
W = 5000 × 0.25
W = 1250J
Therefore, 1250Joules of work is done by the jack.
