From 10 m/s to 30 m/s in 4 seconds, the net force acting on the car is in the forward direction. From 30 m/s to 20 m/s in 2 seconds, net force acting on the car is in the opposite direction.

The net force acting on the car is proportional to the acceleration of the car. During the first interval, the car's acceleration is from 10 m/s to 30 m/s in 4 seconds, which means it is accelerating and therefore there must be a net force acting on the car in the forward direction. During the second interval, the car slows down from 30 m/s to 20 m/s in 2 seconds, which means it is decelerating and therefore there must be net force acting on the car in opposite direction.

Explanation:

By Kirchoff's laws, I1 + I2 = 3

I2 = 3 - I1

Following circuit on the left, V = summation of IRs

9 = I1*3 + 3*2

3*I1 = 9 - 6 = 3

I1 = 1A

I2 = 3 -1 = 2A

Following circuit on the right, V = summation of IRs

ε = I2*4.5 + 3*2

= 2*4.5 + 6

= 15V

Answer:

Population 1 indicates growth while Population 2 indicates a declining population

Explanation:

Here, using the given rate of change of the population, we want to determine which of the two is growing and which is declining

From the rate of change of both, we can determine this. Looking at the differential equation for the first one, we can see that it is of positive value. Looking at the differential equation for the second one. we can see it is of negative value

While a positive change rate indicates growth, a negative change rate will indicate otherwise

Hence, we can conclude that the one with a negative rate change will indicate a declining population

We will have the following:

So, the potential energy is 4.9 Joules.

Analyze system dynamics and design compensator to achieve desired response by selecting compensator zero and canceling one pole of GHP(z).

To select a compensator zero to cancel one pole of GHP(z), we need to use the given angle condition:

Zzero - (pole(1) + Zpole(B)) = 180°

Here, Zzero represents the compensator zero, pole(1) represents the first pole of GHP(z), and Zpole(B) represents the compensator pole.

Let's proceed with the solution step by step:

1. First, we need to determine the value of Zzero. The angle condition states that Zzero = Zpole(1), which means the compensator zero is equal to the first pole of GHP(z).

2. Now, we need to find the value of Zpole(B). We can rewrite the angle condition as follows:

Zpole(B) = Zzero - pole(1) + 180°

Since we already know that Zzero = Zpole(1), we can substitute Zzero in the above equation:

Zpole(B) = Zpole(1) - pole(1) + 180°

Simplifying further:

Zpole(B) = 180°

Therefore, the value of Zpole(B) is 180°.

To summarize, we can select the compensator zero (Zzero) to cancel one pole of GHP(z) as Zpole(1), and the compensator pole (Zpole(B)) is determined to be 180° based on the given angle condition.

U₂ = 0 V. The lamp (L₂) is short circuited, meaning that there is no resistance between its terminals. As such, the voltage across its terminals must be zero.

Resistance is a concept in physics that measures the opposition to the flow of electric current, heat, light, sound, or any other form of energy or matter. It is the measure of how much an object, material, or system resists the flow of electric current, heat, light, sound, or any other form of energy or matter.

a) U₂ = 0 V. The lamp (L₂) is short circuited, meaning that there is no resistance between its terminals. As such, the voltage across its terminals must be zero.

b) U₁ = 12 V. Since the generator is providing a constant voltage of 24 V across its terminals, the voltage across the terminals of (L₁) will be half of this, i.e. 12 V. As the lamps are identical, the current I' through the circuit will also be 0.6 A.

c) (L₁) may burn out due to the large amount of current it is carrying. If the current is too high, it may exceed the rated capacity of the lamp and lead to its failure.

d) (L₁) does not burn out because the circuit includes a fuse. The fuse is designed to break the circuit in the event of an excessive current, thus protecting the lamp from burning out. When the fuse blows, the circuit is broken and the lamp will be off.

As there is an equal and opposite reaction to every action, Newton's Third Law of Motion is applicable in this case. Lisa has filled one of the boxes with books, making it very heavy. When she tries to lift it, the box exerts a force on her, while she also exerts a force on the box due to her efforts to lift it. The result is that the box is too heavy for her to lift.The opposite reaction is the increased force required to lift the box.Therefore, Newton's Third Law of Motion applies in this situation.

The average speed of the particles in terms of the speed of light is 0.976c. Given that, The particle-X has a lifetime of 256.2.A particle track detector is used to measure the speed of particles. On average, the particles leave 10.6 cm long tracks before they decay into other particles that are not observable by the detector.

The formula to calculate the average speed of the particles is given as;v = d / t Where,v = velocity of the particles, d = distance traveled by the particles, and t = time taken by the particles. The distance traveled by the particles before they decay is 10.6 cm = 0.106 m. The lifetime of the particle is given as 256.2 s. Therefore, time taken by the particle to decay, t = 256.2 s.

The speed of the particles can be calculated as follows; v = d / tv = 0.106 / 256.2v = 4.135 × 10^-4 m/s The speed of the particles in terms of the speed of light can be calculated as follows; Speed of light = 3 × 10^8 m/s Average speed of the particles in terms of the speed of light, v/c= (4.135 × 10^-4) / (3 × 10^8)= 0.976 × 10^-8= 0.976cTherefore, the average speed of the particles in terms of the speed of light is 0.976c.

The force constant of the spring is 200.696 N/m & The height the object achieves when the spring releases its energy is 2.5087 m

The spring constant is the force needed to stretch or compress a spring, divided by the compressive or expansive distance. It's used to determine stability or instability in the spring, and therefore the system it's intended for. we know,

F = kx

Therefore,

k = F/x

We also know that the force being exerted on the spring is equal to the mass of the object. Hence, F = mg = 5.13 * 9.8 N = 50.174 N and we know compression due to the mass is 0.25m. Therefore,

K = 50.174/0.25 N/m

K = 200.696 N/m

Therefore, The Spring Constant is 200.696 N/m

On release, the spring potential energy gets converted to kinetic energy. Hence, on release, the height attained by the object is given by:

h = \(1/2 kx^{2}\)

We know that k=200.696 N/m and x=0.25 m. Therefore the height is:

h = \(1/2 (200.696 N/m)(0.25 m)^{2}\)

h = 2.5087 m

Therefore, the force constant of the spring is 200.696 N/m & The height the object achieves when the spring releases its energy is 2.5087 m
