Answer: 20,734.69 N/m
Explanation:
The elastic potential energy (ELPE) of the rubber band is given by

where
k is the spring constant
x = 0.035 m is the stretching of the rubber band
E = 12.7 J is the ELPE of the rubber band
Substituting the numbers and re-arranging the equation, we find

Answer:
d = 2,042 10-3 m
Explanation:
The laser diffracts in the circular slit, so the process equation is
d sin θ= m λ
The first diffraction minimum occurs for m = 1
We can use trigonometry in the mirror
tan θ = Y / L
Where L is the distance from the Moon to Earth
Since the angle is extremely small
tan θ = sin θ / cos θ
Cos θ = 1
tant θ = sin θ = y / L
We replace
d y / L = λ
d = λ L / y
Let's calculate
d = 532 10⁻⁹ 3.84 10⁶/1 10³
d = 2,042 10-3 m
The time taken for him to move the bin 6.5 m is 2.30 s.
The given parameters;
- <em>weight of the load, w = 557 N</em>
- <em>force applied , F = 410 N</em>
- <em>angle of force, = 15°</em>
- <em>coefficient of kinetic friction = 0.46</em>
- <em>distance moved, d = 6.5 m</em>
The net horizontal force on the recycling bin is calculated as follows;

where;
- <em>m is the mass of the recycling bin</em>
- <em />
<em> is the frictional force </em>
W = mg

The net horizontal force on the recycling bin is calculated as;

The time taken for him to move the bin 6.5 m is calculated as follows;

Thus, the time taken for him to move the bin 6.5 m is 2.30 s.
