Explanation:

Seven colours mix together to create a white light they are same as rainbow colour.

red,
orange,
yellow,
green,
blue,

violet.

The above colours mixed together to create white light. Those are the colours of the rainbow.

So to create a white light the seven colours have to mix up together.

Those seven colours are the colours in the rainbow.

So the colours of rainbow light together creates white light.

So to create white light the combination of all colours of rainbow is needed.

Assume it takes 10 J to stretch a spring 10 cm beyond its natural length. Find the work required (in Joules) to stretch the spri

Lady bird [3.3K]

Answer:

W = 30 J

Explanation:

given,

Work done = 10 J

Stretch of spring, x = 0.1 m

We know,

dW = F .dx

we know, F = k x

$\int dW = \int_0^{0.1} k.x dx$

$W = \int_0^{0.1} k.x dx$

$W = k[\dfrac{x^2}{2}]_0^{0.1}$

$10 = k\dfrac{0.1^2}{2}$

k = 2000

now, calculating Work done by the spring when it stretched to 0.2 m from 0.1 m.

$W = \int_{0.1}^{0.2} 2000 x dx$

$W = 2000 [\dfrac{x^2}{2}]_{0.1}^{0.2} dx$

W = 1000 x 0.03

W = 30 J

Hence, work done is equal to 30 J.

Calculate the energy and power required for a student to bike their way to college from home. The student bikes from home for 0.

gregori [183]

Answer:

Check the explanation

Explanation:

To solve the problem, we need to analyze all forces acting on a bicycle individually. In question, student bikes on flat terrain so gravity force doesn't affect the road load. This is the case of uniform acceleration and deceleration so need to calculate average velocity to find Air resistance.

Kindly check the attached images below to see the step by step explanation to the question above.
