Answer:
Work is the energy required to move an object from one point to another. while power is the energy transferred per unit time.
Energy can also be defined as the ability to do work.
374.5m/s
Explanation:
acceleration, a = 9.8m/s²
distance, s = 210m
final velocity, v = 380m/s
unknown:
Initial velocity, u = ?
Solution:
We need to apply one of the equations of motion to solve this problem. The most fitting one is:
V² = U² + 2as
U is the unknown:
U² = V² - 2as
U² = 380² - 2x 9.8 x 210
U² = 144,400 - 4,116 = 140284
U = √140284 = 374.5m/s

Answer:9A
Explanation:
let the last wire be wire C
According to Kirchhoff's rule
the sum of all currents entering a junction must be equal to the sum of all currents leaving a junction
Ic=Ia+Ib
Ic= 4+5
Ic=9A
The answer is 2. The number 2 does not go into 55 evenly, therefore making it not a factor. All the others are factors. You can solve this using the factor list method.
Factors of 55
<em>1, 55</em>
<em>5, 11</em>
<em>11, 5</em>
<em>55, 1</em>
This works for all problems involving factoring.
