Answer:

\frac{dh}{dt} = 0.05 m/min

Explanation:

As we know that the dimensions of the base of the tank is given as

L = 2 m

W = 3 m

now the base area is given as

A = 2m \times 3 m

A = 6 m^2

now we know that volume of the liquid filled in the tank is given as

V = Area \times height

V = 6 \times h

now we will differentiate it with respect to time both sides

\frac{dV}{dt} = 6 \times \frac{dh}{dt}

here we know that

\frac{dV}{dt} = 0.3 m^3/min

now we have

0.3 m^3/min = (6 m^2) \frac{dh}{dt}

\frac{dh}{dt} = 0.05 m/min

A 2290 kg car traveling at 10.5 m/s collides with a 2780 kg car that is initially at rest at the stoplight. The cars stick toget
avanturin [10]

Answer:

0.41

Explanation:

given,

mass of the car, m = 2290 Kg

initial speed = 10.5 m/s

mass of another car, M = 2780 Kg

distance moved = 2.80 m

coefficient of friction = ?

conservation of energy

m u = (M + m) V

2290 x 10.5 = (2290 + 2780) V

V = 4.74 m/s

using equation of motion

v² = u² + 2 a s

4.74² = 2 x a x 2.8

a = 4.02 m/s²

now using equation

a = μ g

4.02 = μ x 9.8

μ = 0.41

A strontium vapor laser beam is reflected from the surface of a CD onto a wall. The brightest spot is the reflected beam at an a
sladkih [1.3K]

Answer:

d=1.29*10^{-6}m

Explanation:

From the question we are told that:

Distance of wall from CD D=1.4

Second bright fringe y_2= 0.803 m

Let

Strontium vapor laser has a wavelength \lambda= 431 nm=>431 *10^{-9}m

Generally the equation for Interference is mathematically given by

y=frac{n*\lambda*D}{d}

Where

d=\frac{n*\lambda*D}{y}

d=\frac{2*431 *10^{-9}m*1.4}{0.803}

d=1.29*10^{-6}m
