100% opacity means the exhaust has no visible smoke and does not block light from a beam projected through the exhaust smoke.

Opacity is a measure of the obstruction of light by a substance. In the context of exhaust smoke, if the opacity is 100%, it indicates that the smoke is completely transparent and does not hinder the passage of light.

This means that no visible smoke is present in the exhaust, and a beam of light can pass through it without any obstruction or blockage. 0% opacity means the exhaust has no visible smoke and does not block light from a beam projected through the exhaust smoke.

Answer:

20743.24 Nm¯²

Explanation:

From the question given above, the following data were obtained:

Initial pressure (P1) = 20000 Nm¯²

Initial temperature (T1) = 23 °C

Final temperature (T2) = 34 °C

Final pressure (P2) =?

Volume = constant

Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

Initial temperature (T1) = 23 °C

Initial temperature (T1) = 23 °C + 273 = 296 K

Final temperature (T2) = 34 °C

Final temperature (T2) = 34 °C + 273 = 307 K

Finally, we shall determine the final (i.e the new) pressure of the tyre.

Initial pressure (P1) = 20000 Nm¯²

Initial temperature (T1) = 296 K

Final temperature (T2) = 307 K

Final pressure (P2) =?

Volume = constant

Since the volume is constant, the final (i.e the new) pressure of the tyre can be obtained by using the following formula:

P1/T1 = P2/T2

20000 / 296 = P2 /307

Cross multiply

296 × P2 = 20000 × 307

Divide both side by 296

P2 = (20000 × 307) /296

P2 = 20743.24 Nm¯²

Therefore, the new pressure of the tyre is 20743.24 Nm¯²

The pole vaulters downward vertical velocity at the end of this second is. 9.81 m/s. The correct option is b.

When an object falls freely under gravity, its velocity increases at a constant rate of 9.81 m/s^2. This acceleration due to gravity is denoted by 'g' and has a magnitude of 9.81 m/s^2 on the surface of the Earth.

In the given problem, the pole-vaulter is falling freely under gravity after clearing the crossbar. The time taken for him to fall is 1.0 s. Therefore, his final downward velocity can be calculated using the formula:

v = g * t

where v is the final velocity, g is the acceleration due to gravity, and t is the time taken for the fall.

Substituting the values, we get:

v = 9.81 m/s^2 * 1.0 s = 9.81 m/s

Therefore, the downward vertical velocity of the pole-vaulter at the end of the second is 9.81 m/s, which is the answer (option b).

According to Freud's theory of psychosexual development, identification refers to a process in which a child models their behavior, attitudes, and personality characteristics after someone of the same sex, usually a parent or caregiver.

In other words, the child identifies with and internalizes the traits and values of the person they see as a role model. Identification plays a crucial role in the formation of gender identity, as the child learns what it means to be a boy or girl based on the behaviors and attitudes they observe from their same-sex parent or caregiver.

This process is believed to occur during the phallic stage of psychosexual development, which occurs between the ages of 3 and 6 years old.During this stage, the child's focus is on their genitalia and they begin to develop a sense of gender identity.

They also experience the Oedipus or Electra complex, which is a desire to possess the opposite-sex parent and a fear of retaliation from the same-sex parent. The child resolves this conflict by identifying with the same-sex parent and adopting their gender role as their own.

This process is essential for the child's development of a healthy sense of self and their ability to navigate relationships with others.

The two changes that would decrease the electric force between two charged particles are to decrease the charge of one of the particles or increase the distance between the particles. Option B and D.

The electric force between two charged particles depends on two factors: the distance between the particles and the magnitude of their charges. To decrease the electric force between two charged particles, we need to change one or both of these factors.

Based on this information, we can eliminate options C and E since they would increase the electric force between the particles. The remaining options are A, B, and D.

A. Decrease the distance between the particles:

This option is incorrect because decreasing the distance between two charged particles would actually increase the electric force between them. This is because the electric force is inversely proportional to the square of the distance between the particles. Therefore, decreasing the distance would increase the force, not decrease it.

B. Decrease the charge of one of the particles:

This option is correct. The electric force between two charged particles is directly proportional to the product of their charges. Therefore, decreasing the charge of one of the particles would decrease the force between them.

D. Increase the distance between the particles:

This option is also correct. As mentioned earlier, the electric force is inversely proportional to the square of the distance between the particles. Therefore, increasing the distance between two charged particles would decrease the electric force between them.

In conclusion, the two changes that would decrease the electric force between two charged particles are to decrease the charge of one of the particles or increase the distance between the particles. Option B and D.

The concept of compactness is related to the curvature of space, as both are determined by the mass distribution of an object. The more compact an object is, the more it will curve space around it. Black holes, being the most dense objects in the universe, curve space to an extreme degree.

Student 2 is correct in pointing out that the Earth is denser than Jupiter, and thus has a higher compactness. However, the Earth's mass is significantly smaller compared to Jupiter's, so the amount of space it curves is also much smaller. In other words, the curvature caused by an object's mass depends on both its density and size.

In conclusion, both students are partially correct. Jupiter, being the largest planet in the solar system, does curve space more than the Earth due to its greater mass. However, the Earth is denser than Jupiter and has a higher compactness, meaning it does curve space to a greater degree for its size.

So This problem doesn’t get anywhere near the precision required that would require consideration of relativistic effects (simple relativity) and thus, they can be ignored. They wouldn’t change the answer within the precision you’re going to use to calculate it.

Note that, Newton’s “Laws” motion are a misnomer. The science community quit calling things “Law(s) of . . . [fill in blank]” over a century ago. They’re not really immutable as Einstein’s “Theory” of Special Relativity turned Newtonian mechanics on its ear. So Everything - all mathematical models used in Physics - they are considered as provisional. They’re good as long as they are consistent, fit observations, and predict things that haven’t been observed yet properly when they are eventually observed. But In other words, they’re not just descriptive models, they’re also predictive as well.

Due to Newton’s “Laws” motion were close, extremely close, so close that they work in nearly all practical, real-world applications, but they weren’t quite complete yet. You need to get past Newtonian Mechanics too - his three “laws” of motion and his “law” of gravity before you launch into special or general relativity and their effects, Thus, you’re a long way away from that.

If a 3,000kg car is pulled with a force of 11,000 N to the right causing it to accelerate at 3 m/s², then the force of friction (F) acting on the car would be 2000 Newtons.

As given in the problem If a 3,000kg car is pulled with a force of 11,000 N to the right causing it to accelerate at 3 m/s²,

The net force acting on the car = 3000 ×3

                                                    = 9000 Newtons

The friction force = 11000 - 9000

W= work done

F=  force applied               s= displacement

Given, work done W= 25 joules= 25 J

∴From equation (1) we get the force required when work is done and displacement is given, that is

F\(=\frac{W}{s}\)                                (2)

∴Force required \(F=\frac{W}{s}= \frac{25J}{0.5m}=50N\)

2.) When the elevator has a deceleration

For the first half -

u = 0 , a = 0.6 , t = t1

v = 0.6(t1)  ---------- ( 1 )

s = 1/2 x 0.6 x (t1)^2 = 0.3(t1^2) -------- ( 2 )

For the second half -

u = 0.6(t1) , a = -0.8 , v = 0

0.6 x (t1) = 0.8 (t2) ----> 3(t1) = 4(t2) ---------- ( 3 )

0.36(t1)^2 = 1.6 s2 ---------- ( 4 )

Now, we know that the total time taken is 10 seconds

------- t1 + t2 =10 , 3t1 = 4t2 ---- t1 = 40/7 , t2 = 30/7

The statement that the frequency of a mass on a spring oscillating vertically is lesser than the frequency of a mass on a spring oscillating horizontally on a frictionless surface is true.

Simple harmonic motion is defined as a periodic motion where the acceleration of the object is directly proportional to the displacement and is always directed towards the equilibrium position. It can be represented mathematically as follows: a = -ω^2x, where a is acceleration, x is displacement and ω is the angular frequency.

Simple harmonic motion can occur in a number of scenarios like a mass-spring system, a pendulum, a vibrating guitar string, etc.The frequency of a mass on a spring oscillating horizontally on a frictionless surface is fh and when the spring is suspended from a hook, and the same mass oscillates vertically, the frequency is fv.

According to the given scenario, the frequency of a mass on a spring oscillating horizontally is greater than the frequency of a mass on a spring oscillating vertically.

The reason behind this phenomenon is that when the mass is suspended from the spring, it experiences weight which acts downwards and stretches the spring.

Thus, the restoring force acting on the spring is given by F = -kx - mg where k is the spring constant, x is the displacement from the equilibrium position, and mg is the force due to gravity.

This force is greater than the restoring force acting on the spring in the horizontal direction which is given by F = -kx. As the restoring force is greater in the vertical case, the frequency of oscillation becomes lesser.

Thus, the statement that the frequency of a mass on a spring oscillating vertically is lesser than the frequency of a mass on a spring oscillating horizontally on a frictionless surface is true.
