In conclusion, the braking force needed to bring the car to a complete stop in 5 seconds is -4000 N.

To calculate the braking force needed to bring a car to a complete stop in 5 seconds, we can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration.
Given that the car has a mass of 2000 kg and is traveling at 10 m/s, we need to find the acceleration first.
Acceleration is the change in velocity over time. In this case, the change in velocity is from 10 m/s to 0 m/s, and the time taken is 5 seconds.
So, the acceleration can be calculated as follows:
Acceleration = (Final Velocity - Initial Velocity) / Time
Acceleration = (0 m/s - 10 m/s) / 5 s
Acceleration = -10 m/s / 5 s
Acceleration = -2 m/s²
Since the car is decelerating, the acceleration is negative.
Now that we know the acceleration, we can calculate the braking force using Newton's second law.
Force = Mass x Acceleration
Force = 2000 kg x -2 m/s²
Force = -4000 N
The negative sign indicates that the force is in the opposite direction to the car's motion, which is necessary to bring it to a stop.
In conclusion, the braking force needed to bring the car to a complete stop in 5 seconds is -4000 N.

The sum of the x components of the forces acting on block 2 is expressed as the equation ∑F2x = Tcos(θ) - mgsin(θ).

A force is defined as the effect that causes the motion of an object with mass to change its velocity that is accelerated. It can be a push or a pull, always with magnitude and direction, making it a vector quantity.

The sum of the x components of the forces acting on block 2 is expressed as the equation ∑F2x = Tcos(θ) - mgsin(θ) where the T is the tension, m is the mass of the block, g is the acceleration of gravity, and θ is the angle of the incline.

This type of equation can be used to calculate the x components of the forces in a variety of situations for example, when the block is being pulled up an incline or when it is in equilibrium.

Thus, the sum of the x components of the forces acting on block 2 is expressed as the equation ∑F2x = Tcos(θ) - mgsin(θ).

At the instant shown, the six scenarios can be ranked in terms of the magnitude of current in the light bulb as follows:

1) Scenario 1 - Here, the battery is directly connected to the light bulb without any other resistors in the circuit. Therefore, the current flowing through the bulb will be the maximum among all the scenarios.

2) Scenario 3 - In this case, the battery is connected to the light bulb through a resistor. However, the resistance is less compared to other scenarios, so the current will be higher than in other cases.

3) Scenario 4 - Here, the battery is connected to the light bulb through a higher resistance compared to scenario 3. This will result in a lesser current in the bulb.

4) Scenario 5 - In this scenario, the battery is connected to the light bulb through a much higher resistance than in the previous two scenarios. Therefore, the current flowing through the bulb will be lower.

5) Scenario 6 - Here, the battery is connected to the circuit in such a way that the current will bypass the light bulb. Therefore, the bulb will not light up and the current flowing through it will be zero.

a. Part A: The area of each plate is required for for a 0.300 uF capacitor is 1.56 × \(10^{-4}\) m².

b. Part B: If the electric field in the paper is not to exceed one-half the dielectric strength, the maximum potential difference that can be applied across the compactor is 2025 V.

To find the area of each plate required for a 0.300 uF capacitor, use the formula:

C = ε₀εrA/d

where C is the capacitance, ε₀ is the vacuum permittivity (8.85 × \(10^{-12}\) F/m), εr is the relative permittivity (dielectric constant), A is the area, and d is the distance between the plates. In this case,

C = 0.300 uF

εr = 2.10

d = 8.10 × \(10^{-5}\) m.

Rearrange the formula to find A:

A = Cd / (ε₀εr)

A = (0.300 × \(10^{-6}\) F)(8.10 × \(10^{-5}\) m) / (8.85 × \(10^{-12}\) F/m × 2.10)

A ≈ 1.56 × \(10^{-4}\) m²

Thus, the area of each plate required for a 0.300 uF capacitor is approximately 1.56 × \(10^{-4}\) m².

To find the maximum potential difference that can be applied across the capacitor, use the formula:

V = Ed

where E is the electric field and d is the distance between the plates. In this case, E is half the dielectric strength (50.0 MV/m / 2 = 25.0 MV/m), and d = 8.10 × \(10^{-5}\) m:

V = (25.0 × 10^6 V/m)(8.10 × 10^-5 m)

V ≈ 2025 V

Thus, the maximum potential difference that can be applied across the capacitor without exceeding one-half the dielectric strength is approximately 2025 V.

Given

a = 3i - 2j

b = -i - 4j

To find,

a+b =?

a-b =?

|a+b| = |(3i - 2j - i - 4j)|

        = |2i - 6j|

        = \(\sqrt{2^{2} + (-6^{2}) }\)

        = \(\sqrt{4+36}\)

        = \(2\sqrt{10}\)

|a-b| = |(3i - 2j) - (-i - 4j)|

       = |3i -2j + i + 4j|

       = |4i + 2j|

       = \(\sqrt{4^{2} + 2^{2} } \\\)

The more kinetic energy I have, the greater the impact it has and, as a result, the further the box will slide away. At the end of the ramp, the kinetic energy between them is NOT equal. Because of its greater mass, kinetic energy has larger potential. Distance reveals the outcome.

they tell us that the voltage is 80% bone

           \(\frac{V}{V_o}\) = 0.80

           t = - RC ln 0.80

To determine the diameter of the cylindrical rod that can withstand a load of 650 N, we need to consider the yield strength of the material and the applied load. the diameter of the rod is approximately 11.62 mm.

By using the formula for stress (force divided by area) and rearranging it to solve for the diameter, we can find the required diameter of the rod.

The stress experienced by the rod can be calculated using the formula:

Stress = Force / Area

Given that the yield strength of the steel is 310 MPa, we can set up the equation:

310 MPa = 650 N / (π * (diameter/2)^2)

We can rearrange the equation to solve for the diameter:

diameter = √(650 N / (310 MPa * π)) * 2

Substituting the given values, we find:

diameter ≈ √(650 / (310 * 10^6 * π)) * 2 ≈ 11.62 mm

The heat lost by water is equal to the heat gained by ice here. The heat lost from water for a temperature change of 25 to 10 degree Celsius is 12300 J.

Calorimetry is an analytical technique used to determine the heat energy absorbed or evolved by a system. The calorimetric equation relating the heat energy q with the mass m, specific heat c and the temperature difference ΔT is :

q = m c ΔT

Here, the heat energy gained by the dry ice is equal to the heat lost from water.

temperature difference for water = 25- 10 °C = 15°C

thus, 15°C is lost from water.

mass of water = 200 g

q =200 g × 4.12 J/°C g × 10°C = 12300 J

Therefore, the heat energy lost from water is 12300 J.

To determine the metallic element (m) that is being plated from the solution, we need to use Faraday's law of electrolysis. According to Faraday's law, the amount of substance (m) that is deposited or plated on an electrode is directly proportional to the electric charge (Q) passed through the electrolyte. The equation is given by:

m = (Q * M) / (n * F)

where:

m is the mass of the substance plated,

Q is the electric charge,

M is the molar mass of the substance,

n is the number of moles of electrons transferred in the reaction,

F is Faraday's constant.

In this case, the electric charge Q is given by the product of the current (I) and time (t): Q = I * t.

From the information provided, the current is 1.57 A and the time is 79.4 s. Plugging these values into the equation, we have:

Q = (1.57 A) * (79.4 s) = 124.558 C

When A car accelerates from 10 m/s to 22 m/s in 6 seconds, the average acceleration of the car is 2 m/s². Hence, option (D) is correct

Acceleration is the rate at which speed and direction of velocity vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates.

Even if the speed is constant, motion on a circle accelerates because the direction is always shifting. Both effects contribute to the acceleration for all other motions.

Initial speed of the car = 10 m/s.

Final speed of the car = 22 m/s.

Time internal = 6 seconds.

The average acceleration of the car is = change in speed/time interval
