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

A car accelerates from 300 km/h to 140 km/h in 2.53 seconds. what is the distance covered?
Snowcat [4.5K]

Answer:

Acceleration = Change in Velocity/Time

Change in Velocity = 36-18 = 18 km/h=5 m/s

Time= 5 Seconds

Acceleration = 5/5= 1 m/s2

Equation of motion,s=ut+(1/2)at2

u=18 km/h=5 m/s

t=5 s

a=1 m/s2

s= (5*5)+(1/2*1*5*5)

s=25+12.5 i.e., s=37.5 m

Hope you are clear with my explanations

Is it possible to produce a continuous and oriented aramid fiber–epoxy matrix composite having longitudinalandtransverse moduli
Masja [62]

Answer:

Not possible

Explanation:

E_{cl} = longitudinal modulus of elasticity = 35 Gpa

E_{ct} = transverse modulus of elasticity = 5.17 Gpa

E_m = Epoxy modulus of elasticity = 3.4 Gpa

V_{\rho l} = Volume fraction of fibre (longitudinal)

V_{\rho t} = Volume fraction of fibre (transvers)

E_f = Modulus of elasticity of aramid fibers = 131 Gpa

Longitudinal modulus of elasticity is given by

E_{cl}=E_m(1-V_{\rho l})+E_fV_{\rho l}\\\Rightarrow 35=3.4(1-V_{\rho l})+131V_{\rho l}\\\Rightarrow 35=3.4-3.4V_{\rho l}+131V_{\rho l}\\\Rightarrow V_{\rho l}=\frac{35-3.4}{131-3.4}\\\Rightarrow V_{\rho l}=0.24764

Transverse modulus of elasticity is given by

E_{ct}=\frac{E_mE_f}{(1-V_{\rho t})E_f+V_{\rho t}E_m}\\\Rightarrow 5.17=\frac{3.4\times 131}{(1-V_{\rho t})131+V_{\rho t}3.4}\\\Rightarrow \frac{3.4\times 131}{5.17}-131=-127.6V_{\rho t}\\\Rightarrow V_{\rho t}=\frac{\frac{3.4\times 131}{5.17}-131}{-127.6}\\\Rightarrow V_{\rho t}=0.35148

V_{\rho l}\neq V_{\rho t}

Hence, it is not possible to produce a continuous and oriented aramid fiber.

Max ran 100 feet in 10 seconds.
Ivanshal [37]

Answer:

for max :

100 feet in 10 secs

for molly :

60 feet in 5 secs = 120 feet in 10 secs

so, molly ran farther in the same time interval i.e. covered 120 feet where as Max covered 100 feet
