Answer:

1.7 g/cm³

Explanation:

Given that:

Density of substance = 3.4 g/cm³

Relative density to another substance = 2

Density of second substance=?

Let density of second substance = x

Relative density = density of substance / density of second substance

Relative density = density of substance / x

2.0 = 3.4g/cm³ / x

2 * x = 3.4 g /cm³

x = 3.4 g/cm³ ÷ 2

x = 1.7 g/cm³

(A) The wavelength of each of these waves when they are sent through sea water is 0.0126 m and 0.0076 m respectively.

(B) The wavelength of each of these waves when they are sent through freshwater is 0.012 m and 0.0074 m respectively.

(C) The time taken for the echo to return to the ship is 3.97 seconds.

The wavelength of the sound wave in sea water depends on the speed of sound in seawater and frequency of the wave.

The speed of sound in seawater, v = 1,510 m/s

λ = v/f

when the frequency, f = 120 kHz

λ = 1510 / 120,000

λ =  0.0126 m

when the frequency, f = 200 kHz

λ = 1510 / 200,000

λ =  0.0076 m

The speed of sound in freshwater, v = 1481 m/s

when the frequency, f = 120 kHz

λ = 1481 / 120,000

λ =  0.012 m

when the frequency, f = 200 kHz

λ = 1481 / 200,000

λ =  0.0074 m

The time taken for the echo to return is calculated as follows

v = 2d/t

t = 2d/v

t = (2 x 3,000 m) / (1510 m/s)

t = 3.97 s

The slope of the graph of the equation at the point (20, 2) is 1/8.

To find the slope of the graph of the equation at the given point (20, 2), we need to find the derivative of the equation with respect to x and evaluate it at x = 20. Let's differentiate the equation implicitly:

xy - 9y^2 = 4

To differentiate implicitly, we treat y as a function of x and apply the chain rule. Differentiating both sides of the equation with respect to x:

1 * y + x * dy/dx - 9 * 2y * dy/dx = 0

Simplifying this equation:

y + x * dy/dx - 18y * dy/dx = 0

Grouping the terms with dy/dx:

dy/dx * (x - 18y) = -y

Now, let's solve for dy/dx by dividing both sides by (x - 18y):

dy/dx = -y / (x - 18y)

Substituting the given point (20, 2) into the equation:

dy/dx = -2 / (20 - 18(2))

         = -2 / (20 - 36)

         = -2 / (-16)

         = 1/8

Inertia is the same thing as mass, more or less. Inertia is the tendency of the object to want to stay in place if at rest, or the object's tendency to stay in motion if a force is applied to it. A train's inertia is massive because it takes a lot of force to move such a large mass, or to slow it down. This is in comparison to the other objects (rubber ball, stone, bike, and the coins).

Answer:

Inertia is the measure of the mass of the body. The greater is the mass of the body; the

greater is its inertia and vice-versa.

(a) Mass of a stone is more than the mass of a rubber ball for the same size. Hence, inertia of

the stone is greater than that of a rubber ball.

(b) Mass of a train is more than the mass of a bicycle. Hence, inertia of the train is greater

than that of the bicycle.

(c) Mass of a five rupee coin is more than that of a one-rupee coin. Hence, inertia of the five

rupee coin is greater than that of the one-rupee coin.

To calculate the Taguchi quality cost, we need to multiply the length of each piece by the Taguchi parameter T, and then sum up the costs.

Given:

Length of the first metal rod = 49.19 cm

Length of the second metal rod = 49.93 cm

a) Taguchi parameter T:

Since we don't have the specific value of T, we cannot calculate it.

b) Taguchi Quality Cost of the second metal rod:

Taguchi Quality Cost = Length of the second metal rod * Taguchi parameter T

c) Taguchi Quality Cost of the first metal rod:

Taguchi Quality Cost = Length of the first metal rod * Taguchi parameter T

d) Total Taguchi Quality Cost of the two units:

Total Taguchi Quality Cost = Taguchi Quality Cost of the first metal rod + Taguchi Quality Cost of the second metal rod

Since we don't have the Taguchi parameter T, we cannot calculate the specific values for parts (b), (c), and (d).

A spherical drop of water carrying a charge of 41pC has a potential of 570 V at its surface (with V=0 at infinity) (a) The radius of the drop is approximately 5.88 micrometers (μm).

(b) The potential at the surface of the new drop formed by combining two drops of the same charge and radius is approximately 1140 V.

(a) To find the radius of the drop, we can use the formula for the potential of a charged sphere, which is given by V = (k * Q) / r, where V is the potential, k is the electrostatic constant, Q is the charge, and r is the radius of the sphere. Rearranging the formula to solve for the radius, we have r = (k * Q) / V. Plugging in the given values of Q = 41 pC (pico coulombs) and V = 570 V, and using the value of k = 8.99 × 10^9 Nm^2/C^2, we can calculate the radius to be approximately 5.88 μm.

(b) When two drops combine to form a single spherical drop, the total charge remains the same. Therefore, the potential at the surface of the new drop can be calculated using the same formula as before, but with the combined charge. Since each drop has the same charge and radius, the combined charge will be 2 times the original charge. Plugging in Q = 82 pC (2 * 41 pC) and using the given value of V = 570 V, we can calculate the potential at the surface of the new drop to be approximately 1140 V.

Answer:

Speed is a scalar quantity it is the rate of change in the distance travelled by an object, while velocity is a vector quantity  it is the speed of an object in a particular direction.

A positive point charge would: (a) Move at constant velocity (b) speed up or slow down depending on the direction and strength of the fields.

If a positive point charge is moving along the +x-axis and there is a magnetic field in the +x-direction, it will continue to move at a constant velocity, as the magnetic field will exert a force perpendicular to the direction of motion.

On the other hand, if there is an electric field in the +x-direction, the charge will speed up as it experiences a force in the direction of motion. If the electric field is in the opposite direction, the charge will slow down.

If both fields are present, the resulting motion of the charge will depend on the direction and strength of the fields.

In some cases, the charge may move in a circular path, while in others, it may continue at a constant velocity or accelerate/decelerate.

The motion of a charged particle in a magnetic or electric field depends on the direction of the field and the velocity of the particle relative to the field.

(a) If there is a magnetic field in the +x-direction, a positively charged particle moving along the +x-axis will experience a force perpendicular to both the direction of motion and the magnetic field direction. According to the right-hand rule, the direction of the force will be in the +y-direction. This force will cause the particle to move in a circular path in the xy-plane around the origin. The particle will continue to move at a constant speed along the x-axis. Therefore, the answer is (a) move at constant velocity.

(b) If there is an electric field in the +x-direction, a positively charged particle moving along the +x-axis will experience a force in the same direction as the electric field. According to the equation F = qE, the force is proportional to the charge of the particle and the strength of the electric field. The force will cause the particle to accelerate in the +x-direction, increasing its speed. Therefore, the answer is (b) speed up.

The power of lens that a far sighted person should use to see at 25 cm clearly is +4.0 D.

The strength of a lens, also known as its power, is measured in diopters (D). The power of a lens is determined by the curvature of the lens and the material from which it is made. The more curved a lens is, the more powerful it is. A convex lens, for example, has a positive power.

Given that, The near point of a far-sighted person = 50 cm

Distance required to see clearly = 25 cm

Power of the lens, P = 1/f, where f = focal length in meters.

We know that the formula to find the power of lens:

P = 1/f

We also know that the distance of the near point is 50 cm.

Therefore, we can calculate the focal length of the lens as follows:

f = 50 cm (since near point is given, and f = 1/d, where d is near point)

Substituting the value of f in the formula to find the power of lens, we get:

P = 1/f = 1/0.50 = 2 D

Since a lens of +2.0 D would be required to focus an object at a distance of 50 cm, the person would need a lens with double the power to focus an object at a distance of 25 cm.

Therefore, the power of lens that a far sighted person should use to see at 25 cm clearly is +4.0 D.

The absence of external force in the outer space, allows the piece of rock to continue moving at the same velocity for thousands of years.

The outer space is almost an absolute vacuum, because it's nearly empty. There is no matter such as air in the outer space that will provide an external force needed to change the velocity of the piece of rock.

From Newton's first law of motion, an object in a state of rest or uniform motion in a straight line, will continue in that state unless it is acted upon by an external force.
