A piece of wire 29 m long is cut into two pieces. One piece is bent into a square and the other is bent into an equilateral tria
skelet666 [1.2K]

Answer:

Explanation:

Total length of the wire is 29 m.

Let the length of one piece is d and of another piece is 29 - d.

Let d is used to make a square.

And 29 - d is used to make an equilateral triangle.

(a)

Area of square = d²

Area of equilateral triangle = √3(29 - d)²/4

Total area,

A = d^{2}+\frac{\sqrt3}{4}\left ( 29-d \right )^{2}

Differentiate both sides with respect to d.

\frac{dA}{dt}=2d- \frac{\sqrt3}{4}\times 2(29-d)

For maxima and minima, dA/dt = 0

d = 8.76 m

Differentiate again we get the

\frac{d^{2}A}{dt^{2}}= + ve

(a) So, the area is maximum when the side of square is 29 m

(b) so, the area is minimum when the side of square is 8.76 m

The energy of the wave will decrease.

The energy of a wave is given as

E = h f

where E = energy of waver

h = plank's constant

f = frequency of the wave.

From the formula , we see that the energy of the wave is directly proportional to the frequency of the wave. hence as the frequency of the wave decrease, the energy of the wave will decrease.

Consider an object with weight on the Earth W_earth. The gravity of the Earth is g. If it is moved to another planet with gravit
Mazyrski [523]

Answer:

W_{Planet} = \frac{W_{Earth}}{g}\times a

Explanation:

We know that weight of an object on Earth is,

W_{Earth} = m\times g

Thus,

m = \frac{W_{Earth}}{g}

where,

m = mass of an object, which is constant and is independent of gravity

g = acceleration due to gravity on Earth

On the new planet, gravity = a

Thus the weight of the object on the new planet will be

W_{Planet} = m\times a

W_{Planet} = \frac{W_{Earth}}{g}\times a
