Answer:

1.7 × 10^1^0

Explanation:

Knowing that, the volume of the sphere is given by, v=\frac{4}{3}\pi ^3

Thus, the fractional change in volume is given by,

=3 × \frac{0.02}{100}=\frac{0.06}{100}

Pressure at the bottom of the sea is,

Δp =pgh = 10^3 × 10 × 10^3=10^7 pa.

Knowing that,

Bulk modulus: \frac{10^7 * 100}{0.06}=\frac{10^9}{6*10^-^2}=\frac{10^1^1}{6}

B =\frac{10}{6}*10^1^0

B = 1.7*10^1^0N/M^2

Answer = 1.7 × 10^1^0

Answer:

Explanation:

Sphere contracts in volume by 0.02%

Change in Depth = 1 km = 1000m

Acceleration due to gravity = 9.8 m/s^2

Density of water = 1000 kg/m^3

Assume the volume of sphere is V

V=4/3*pi*R^3

So, dV=4*pi*R^2*dR

dV/V = 4*pi*R^2*dR / 4/3*pi*R^3

= 3*dR/R

Given dR/R = 0.02%

dV/V=3*0.02/100

= 6*10^(-4)

Water pressure at 1km (1000m) deep water

P=ρgH

= 1000*9.8*1000

= 9.8*10^6 N/m^2

Bulk modulus, K, is given by

= P / (dV/V)

= ​9.8*10^6 / 6*10^(-4)

= 1.63*10^10 N/m^2

The vehicles are fitted with shockers why​
MissTica

Shockers acts as a shock absorber in the vehicle making the ride comfortable. When vehicle goes on rough road then it gets shocks from the road deformities the springs present in the shockers provide counter force and thus making the vehicle stable ride without shock.
