"At maximum absorbance, the colour of the at wavelength of maximum absorbance is absorbed, while the other wavelengths are observed."

The maximum absorbance wavelength of white light is subtracted by absorption when it strikes an object, leaving the leftover wavelengths to be reflected to the eye.

Maximum absorbance is the frequency at which coloured light is most effectively absorbed.

The colour at the wavelength of maximum absorbance is subtracted by absorption at maximum absorbance, and the residual colours are reflected to the eye.

For instance, plants refract green light while absorbing red and blue light, which is why they are green.

Because of this, at maximum absorbance, the colour at the maximum absorbance frequency is absorbed while the other wavelengths are visible.

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.

Thus, 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.

Answer:

We can use the law of conservation of momentum to solve this problem. According to this law, the total momentum of the system before the collision is equal to the total momentum of the system after the collision.

Let's define the positive direction to be the direction of motion of the 300g ball before the collision. Then the initial momentum of the system is:

p1 = m1 * v1 + m2 * v2

where m1 and v1 are the mass and velocity of the 300g ball, and m2 and v2 are the mass and velocity of the 200g ball, respectively.

Substituting the given values, we get:

p1 = (0.3 kg) * (34 cm/s) + (0.2 kg) * (15 cm/s)

p1 = 12.9 kg cm/s

After the collision, the 200g ball moves with a velocity of 36 cm/s. Let's call the final velocity of the 300g ball v3. Then the final momentum of the system is:

p2 = m1 * v3 + m2 * 36 cm/s

Substituting the given values, we get:

p2 = (0.3 kg) * v3 + (0.2 kg) * (36 cm/s)

p2 = 0.3 kg v3 + 7.2 kg cm/s

Since the total momentum of the system is conserved, we have:

p1 = p2

Substituting the values, we get:

12.9 kg cm/s = 0.3 kg v3 + 7.2 kg cm/s

Solving for v3, we get:

v3 = (12.9 kg cm/s - 7.2 kg cm/s) / 0.3 kg

v3 = 18 cm/s

Therefore, the velocity of the 300g mass after the collision is 18 cm/s.

Answer:

(a) η = 0.1742 = 17.42 %

(b) W = 31.64 W

(c) m = 0.58 kg

Explanation:

(a)

The efficiency of a Carnot's engine is given as follows:

\(\eta = 1-\frac{T_2}{T_1}\)

where,

η = efficiency = ?

T₁ = source temperature = 100°C + 273 = 373 K

T₂ = sink temperature = 35°C + 273 = 308 K

Therefore,

\(\eta = 1 - \frac{308\ k}{373\ k} \\\)

η = 0.1742 = 17.42 %

(b)

Another formula for the efficiency of Carnot's Engine is:

\(\eta = 1 - \frac{Q_2}{Q_1}\)

where,

Q₁ = Input heat rate

Q₂ = Heat rejected = 150 W

Therefore,

\(0.1742 = 1 - \frac{150\ W}{Q_1}\\\\ \frac{150\ W}{Q_1} = 1-0.1742\\\\Q_1 = \frac{150\ W}{0.8258}\)

Q₁ = 181.64 W

Now, for the useful power output:

\(W = Q_1-Q_2\\W = 181.64\ W - 150\ W\\W = 31.64\ W\)

where,

W = Useful Output

W = 31.64 W

t = time = 2 h = 7200 s

H = Latent heat of condensation of steam = 2260 KJ/kg = 2260000 J/kg

Therefore,

\(m = \frac{(181.64\ W)(7200\ s)}{(2260000\ J/kg)}\)

Explanation:

They have become less aligned and point in the opposite direction of their counterparts, resulting in a loss of magnetism and a drop in the magnetic field.

The pattern observed is that the capacitance decreases as the dielectric constant of the insulator decreases. This is as shown below.

Dielectric Constant (K)  Capacitance (C)

1                    5                      4.43 × 10⁻¹³

2                   4                      4.16 × 10⁻¹³

4                   1                       0.89 × 10⁻¹³

Plate area, A = 100.0 mm2

Separation between the plates, d = 10.0 mm

Dielectric constants, K = 5, 4, 3, 1.

Capacitances, C = ?

The capacitance of a capacitor is given by the formula,

C = ε₀KA/d,

where ε₀ = 8.85 × 10−¹² F/m² is the permittivity of free space.

Substituting the values of A, d, K, and ε₀, we get

C = (8.85 × 10−¹² × 100 × K) / 10.The table can be filled as follows:

3                   3                      3.54 × 10⁻¹³

4                   1                       0.89 × 10⁻¹³

Dielectric Constant (K)

Capacitance (C)

5C = (8.85 × 10⁻¹² × 100 × 5) / 10 = 4.43 × 10⁻¹³ F

4C = (8.85 × 10⁻¹² × 100 × 4) / 10 = 4.16 × 10⁻¹³ F

3C = (8.85 × 10⁻¹² × 100 × 3) / 10 = 3.54 × 10⁻¹³ F

1C = (8.85 × 10⁻¹² × 100 × 1) / 10 = 0.89 × 10⁻¹³ F

The pattern observed is that the capacitance decreases as the dielectric constant of the insulator decreases. The highest capacitance is observed when the dielectric constant is 5 and the lowest capacitance is observed when the dielectric constant is 1.

This is because the higher the dielectric constant, the more charge can be stored in the capacitor, resulting in a higher capacitance.

Answer:

The thickness of the tissue is : 2.4 x 10⁷ mm

Explanation:

The general formula for speed is the distance travelled divided by the time taken.

In this case,

Speed = 1600 m/s  ------speed of sound in human tissue

Time = 1.5 * 10 seconds -----time of taken for the ultrasound pulse to go through a certain thickness of a tissues

The thickness of the tissue here is the distance as per the speed formula, hence;

Tissue thickness = Speed of sound * time taken by ultrasound pulse

Tissue thickness= 1600 * 1.5*10 =24000 m

1 m= 1000 mm

24000m = 24000*1000 mm

= 2.4 x 10⁷ mm
