There are several reasons why it is impossible for nuclear energy to completely replace oil and gas in the future. First and foremost, the infrastructure required to generate nuclear energy is highly expensive and complex.

Additionally, nuclear reactors require a significant amount of time and resources to construct, and safety protocols must be strictly enforced to prevent catastrophic accidents. Furthermore, nuclear waste management is a major challenge that is still being addressed by the industry. Additionally, nuclear energy is not a renewable source of energy like solar and wind energy, which means that nuclear fuel is finite and will eventually run out. Even if all of the world's oil and gas reserves were depleted, nuclear energy would still not be a viable option for replacing them due to these limitations. Overall, while nuclear energy can provide a substantial amount of energy and play a role in reducing carbon emissions, it cannot entirely replace oil and gas as a source of energy in the future.

C) In short time exposures, their images looked stellar.

The term "quasi-stellar" in quasars refers to the appearance of these objects in short time exposures. When observed with limited exposure time, quasars appear star-like or stellar in nature. This is because their intense luminosity is concentrated in a very small region, giving them a point-like appearance similar to stars. However, upon closer examination and with longer exposures, the unique characteristics of quasars become evident. Quasars are actually highly energetic and distant celestial objects that emit enormous amounts of radiation across a wide range of wavelengths. They are powered by supermassive black holes at the centers of galaxies, which accrete matter and release vast amounts of energy. Their spectra show distinct emission lines and other characteristics that distinguish them from ordinary stars.
So, while quasars initially appear stellar in short exposures, their true nature and extraordinary properties become apparent through detailed observations and analysis.

The value of force is 1.7 × 10⁻³ N, with the direction opposite to that of the bat's motion.

When an object collides with another object, they exchange energy. For example, a baseball and bat collision or a car collision. When two objects collide, the force of the collision has to be equal on both sides of the collision according to Newton's Third Law. So, to find the value of force, we will apply the equation:

F = ΔP / ΔT

where F is the force, ΔP is the change in momentum, and ΔT is the time of collision. The equation represents the impulse momentum theorem.

Now, let's apply the given values to the above equation.

Final momentum (p2) = mass × final velocity (v2)

p2 = 0.15 kg × (-50 m/s)

p2 = -7.5 kg.m/s

Initial momentum (p1) = mass × initial velocity (v1)

p1 = 0.15 kg × (40 m/s)

p1 = 6 kg.m/s

Change in momentum (ΔP) = p2 - p1

ΔP = -7.5 kg.m/s - 6 kg.m/s

ΔP = -13.5 kg.m/s

Time of collision (ΔT) = 8.0 × 10³ s

Now, putting the values of ΔP and ΔT in the equation of impulse momentum theorem, we get:

F = ΔP / ΔT

F = -13.5 kg.m/s ÷ 8.0 × 10³ s

F = -1.7 × 10⁻³ N

Thus, the value of force is 1.7 × 10⁻³ N, with the direction opposite to that of the bat's motion.

The focal length of the lens is approximately 115.3 cm. The explaination is  explained below.

To find the focal length of the lens, we can use the lens formula:

1/f = 1/v - 1/u

Where:

f is the focal length of the lens

v is the distance of the image from the lens

u is the distance of the object from the lens

Given:

v = 38.5 cm

u = 57.8 cm

Let's substitute these values into the formula:

1/f = 1/38.5 - 1/57.8

Now, let's calculate the right side of the equation:

1/f = (57.8 - 38.5) / (38.5 * 57.8)

= 19.3 / (2223.3)

≈ 0.008677

Now, we can find the focal length (f) by taking the reciprocal of both sides:

f = 1 / (0.008677)

≈ 115.3 cm

Therefore, the focal length of the lens is approximately 115.3 cm.

The potential difference when a charge goes from 10m to 16m is approximately -1.6875 x \(10^9\) V. The negative sign indicates a decrease in potential as the charge moves farther away from the uniformly charged shell.

To calculate the potential difference between two points, we can use the formula:

V = k * (Q / r)

V is the potential difference

k is the electrostatic constant (k = 9 x \(10^9 N m^2/C^2\))

Q is the charge

r is the distance

In this case, the charge (Q) is 5C and the distances (r) are 10m and 16m.

First, let's calculate the potential at the initial point (10m):

V_initial = k * (Q / r_initial)

V_initial = (9 x \(10^9 N m^2/C^2\)) * (5C / 10m)

V_initial = 4.5 x \(10^9\) V

Next, let's calculate the potential at the final point (16m):

V_final = k * (Q / r_final)

V_final = (9 x \(10^9 N m^2/C^2)\) * (5C / 16m)

V_final = 2.8125 x\(10^9\) V

Finally, we can calculate the potential difference (ΔV) between the two points:

ΔV = V_final - V_initial

ΔV = 2.8125 x \(10^9\) V - 4.5 x\(10^9\) V

ΔV = -1.6875 x \(10^9\) V

Answer:

Her linear velocity on the outer edge is 3 m/s

Her rotational velocity, is constant at 2 RPM

Explanation:

The given parameters are;

The radius of the rotating platform = r

The linear velocity  v(t) = 1 m/s

The position Emily is riding = 1/3 the distance from the center

The rotational velocity = 2 RPM = 2 Revolutions per minute

The formula for angular velocity, ω is given as follows;

ω = θ/t

Where;

θ = The angle rotated

t = The time taken for the rotation

Given that the rotational velocity = 2 RPM

1 revolution = 2·π radians

The angular velocity, ω = 2×π×(2 RPM) = 4·π rad/min = 4·π/60 rad/seconds

ω = 4·π/60 rad/seconds

The linear velocity, v = r₁×θ/t = r₁×ω

Where;

r₁ = 1/3 × r

v = 1 m/s = 1/3 × r  × 4·π/60 rad/seconds

∴ r = 1/(1/3 × 4·π/60) = 45/π meters

r = 45/π meters

Therefore her linear velocity, v₂ and her rotational velocity if she moves to the outer edge will be given as follows;

v₂ = r × ω = 45/π × 4·π/60 = 3 m/s

Her linear velocity on the outer edge, v₂ = 3 m/s

Her rotational velocity, remains at 2 RPM.

C. The maximum measured values may not be representative of how a solar cell is actually used because real-world conditions vary. Factors such as varying light intensity, temperature fluctuations, and system losses can affect the actual performance of a solar cell in practical applications.

ii. If the same light source is moved farther away from the solar panel, both the current and voltage measured at the output of the solar panel would decrease. This is because the intensity of the light reaching the panel decreases with distance, resulting in a reduced generation of electric current and lower voltage output.

iii. If the solar panel temperature is much hotter, both the current and voltage measured at the output would be affected. Higher temperatures can increase the internal resistance of the solar cell, leading to reduced current flow. Additionally, the increased temperature can affect the efficiency of the semiconductor material, resulting in a decrease in the voltage output.

iv. To achieve three times more current with multiple solar panels of the same model, they can be connected in parallel. Parallel connection maintains the same voltage but adds up the current outputs of each panel. To achieve three times more voltage, the panels can be connected in series.

Answer:

New volume, v2 = 0.8L

Explanation:

Given the following data;

Original Volume = 2L

Original Temperature = 280K

New Temperature = 700K

To find new volume V2, we would use Charles' law.

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles is given by;

\( VT = K\)

\( \frac{V1}{T1} = \frac{V2}{T2}\)

\( \frac{V1}{T1} = \frac{V2}{T2}\)

Making V2 as the subject formula, we have;

\( V_{2}= \frac{V1}{T1} * T_{2}\)

\( V_{2}= \frac{2}{700} * 280\)

\( V_{2}= 0.0029 * 280\)

V2 = 0.8L

Therefore, the volume of the gas after it is heated is 0.8L.

The speed of the other object formed is 4.8 m/s.

The change in kinetic energy is 9.84 J.

Mass of the first object, m₁ = 3 u

Velocity of the first object, v₁ = 0.8 c

Mass of the second object, m₂ = 4 u

Velocity of the second object, v₂ = 0.6 c

Mass of the object at rest, m' = 6 u

a) According to the conservation of momentum,

m₁ + m₂ = m'+ m

So, m = (3 + 4) - 6

m = 7 - 6 = 1 u

m₁v₁ + m₂v₂ = (m x v) + (m' x v')

(3 x 0.8) + (4 x 0.6) + (1 x v) + (6 x 0)

Therefore, the speed of the other object formed is,

v = 2.4 + 2.4

v = 4.8 m/s

b) The change in kinetic energy is given by,

E = KE - (KE₁ + KE₂)

E = 1/2mv² - (1/2m₁v₁² + 1/2m₂v₂²)

E = 1/2(mv² - m₁v₁² - m₂v₂²)

E = 1/2[(1 x (4.8)² - 3 x (0.8)² - 4 x (0.6)²]

E = 1/2(23.04 - 1.92 - 1.44)

E = 1/2 x 19.68
