Calculate the workdone to stretch an elastic string by 40cm if a force of 10 newton produces an extension of 4cm in it
notka56 [123]

Answer:

Workdone = 20 Joules

Explanation:

Given the following data;

Force = 10N

Extension, e = 4cm to meters = 4/100 = 0.04 meters

Workdone extension = 40cm to meters = 40/100 = 0.4 meters

To find the work done;

First of all, we would find the spring constant using the formula;

Force = spring constant * extension

10 = spring constant * 0.04

Spring constant = 10/0.04

Spring constant = 250 N/m

Next, we find the work done;

Workdone = ½ke²

Where;

k is the spring constant.

e is the extension.

Substituting into the formula, we have;

Workdone = ½ * 250 * 0.4²

Workdone = 125 * 0.16

Workdone = 20 Joules

Candace is interested in learning more about colors. Which question about colors could be answered through scientific investigat
NeTakaya
Hi!

I believe that there were the following options in this question:

<span>A) Which color bends the most to make a rainbow?
B) What color of scented marker has the best smell?
 C) Which flower has the prettiest shade of purple on its petals?
 D) What is the best-looking color on a high-performance sports car</span>

Now, options b), c) and d) are about a personal preference and opinion - they are not scientific uqestions.
The correct answer is a) - it asks about the properties of light.

A thin wire of length (2 m) and (1 mm2 ) cross-section area is clamped horizontally between two walls, a weight of (10 kg) is hu
allsm [11]

Answer:

Young modulus  = 9.8 × 10⁹ N/m²

Explanation:

From the information given:

Stress = F/A

Stress = (10 × 9.8) / 0.001²

Stress = 9.8× 10⁷ N/m²

Strain = increase in length / initial length of wire

Strain = 0.02/ 2

Strain = 0.01

Now;

The Young modulus (Y)= stress/strain

Young modulus  = (9.8 × 10⁷ N/m²) /  0.01

Young modulus  = 9.8 × 10⁹ N/m²

a delivery truck travels 18 blocks north, 10 blocks east, and 16 blocks south. what is the distance traveled and displacement. ​
AleksAgata [21]

1) Distance: 44 blocks

2) Displacement: 10.2 blocks at 11.3^{\circ} north of east

Explanation:

1)

- Distance is a scalar quantity that gives a measure of the total length of the path travelled by an object, regardless of its direction

- Displacement is a vector quantity which connects the initial position to the final position of motion of the object. Being a vector, it has both magnitude and direction: the magnitude is the shortest distance between initial and final position, while the direction goes from the initial to the final position.

In this problem, the motion is:

18 blocks north

10 blocks east

16 blocks south

So, the distance is the sum of the distances covered in each part:

distance = 18 + 10 + 16 = 44 blocks

2)

The displacement can be calculated by evaluating the initial and the final position. Along the north-south direction, the displacement is

d_y = 18 (n) - 16 (s) = 2 blocks north

Along the east-west direction,

d_x=10 blocks east)

So, the magnitude of the displacement is given by Pythagorean's theorem

d=\sqrt{d_x^2+d_y^2}=\sqrt{2^2+10^2}=10.2 blocks

And the direction is given by

\theta=tan^{-1}(\frac{d_y}{d_x})=tan^{-1}(\frac{2}{10})=11.3^{\circ}

measured as north of east.
