Young's Modulus of elasticity is a) Shear stress/Shear strain b) Tensile stress/Shear strain 9. c) Shear stress /Tensile strairn

slava [35]

Answer:

Option C is the correct answer.

Explanation:

Young's modulus is the ratio of tensile stress and tensile strain.

Bulk modulus is the ratio of pressure and volume strain.

Rigidity modulus is the ratio of shear stress and shear strain.

Here we are asked about Young's modulus which is the ratio of tensile stress and tensile strain.

Option C is the correct answer.

A speed skater goes around a turn with a 31 m radius. The skater has a speed of 14 m/s and experiences a centripetal force of 46

dybincka [34]

Answer:

Mass of the skater, m = 72.75 kg

Explanation:

It is given that,

Radius of the circular path, r = 31 m

Speed of the skater, v = 14 m/s

Centripetal force, F = 460 N

We need to find the mass of the skater. It can be determined using the formula of centripetal force. It is given by :

$F=\dfrac{mv^2}{r}$

$m=\dfrac{Fr}{v^2}$

$m=\dfrac{460\ N\times 31\ m}{(14\ m/s)^2}$

m = 72.75 kg

So, the mass of the skater is 72.75 kg. Hence, this is the required solution.

An ecology center wants to set up an experimental garden using 400 meters of fencing to enclose a rectangular area of 9900 squar

blsea [12.9K]

Explanation:

Given that,

Fencing to be done, P = 400 m

Area of the rectangular garden, $A=9900\ m^2$

Let l is the length and b is the breadth of the garden. The area of the rectangle is given by :

$A=l\times b$

$lb=9900$ ............(1)

The perimeter of the garden is given by :

$P=2(l+b)$

$400=2(l+b)$

$200=(l+b)$ ...............(2)

On solving equation (1) and (2), we get the value of l and b are as follows :

l = 90 m and b = 110 m

or

b = 90 m and l = 110 m

So, the dimension of the garden is 90 m by 110 m. Hence, this is the required solution.
