Jose lifts a 24N box with a force of 57N. What is the resulting net force?

Answer:C car

Explanation:

8.2 X \(10^{5}\)C quantity of charge is supplied by the battery to charge the capacitors.

\(C_{net } = \frac{C_{1} C_{2} }{C_{1} +C_{2} }\)

       = \(\frac{3\times 4}{3+4}\)

     = 12/17

    = 1.714μ F

Q = CV

     = 1.714x \(10^{6}\) F X 48V

     = 82.27x \(10^{6}\)C

     = 8.2 X \(10^{5}\)C

A two-terminal electrical device known as a capacitor is capable of storing energy in the form of an electric charge. It is made up of two electrical wires that are spaced apart by a certain amount. Suction may be used to fill the space between the conductors, or a dielectric, an insulating substance, may be used instead. Capacitance is the term used to describe a capacitor's capacity to hold charges.

Pairs of opposing charges are held apart in capacitors to retain energy. A parallel plate capacitor has the most basic construction and is made up of two metal plates with a space in between them. However, many capacitor types are produced in a wide variety of shapes, sizes, lengths, girths, and materials.

As water fills the container halfway, the buoyant force is equal to the weight of the liquid, according to the Archimedes principle. V=0.5 L and the container is subject to a 5 N buoyant force.

The upward force applied to an object that is fully or partially submerged in a fluid is known as the buoyant force. Upthrust is another name for this upward thrust. A body submerged partially or completely in a fluid appears to shed weight, or to be lighter, due to the buoyant force.

When an object is submerged in water or any other liquid, we notice that it receives a force opposite the gravitational pull from the downward direction, which results in a loss of weight. The fluid's upward force works against the weight of an object submerged in the fluid. As we are well aware, a fluid column's pressure rises with depth.

To determine the acceleration vector just after the rock is launched, we need to separate the acceleration into its x-component and y-component.

Here, acceleration due to gravity is approximately 9.8 m/s² downward, we can determine the x- and y-components of the acceleration vector as follows:

x-component: The horizontal acceleration remains constant and equal to 0 m/s² since there is no acceleration in the horizontal direction (assuming no air resistance).

y-component: The vertical acceleration is influenced by gravity, which acts downward. The y-component of the acceleration is given by:

ay = -9.8 m/s²

Therefore, the acceleration vector just after the rock is launched is:

To calculate the approximate thermal energy in kilojoules per mole (kJ/mol) of molecules at a given temperature, you can use the Boltzmann constant (k) and the ideal gas law.

The Boltzmann constant (k) is approximately equal to 8.314 J/(mol·K). To convert this to kilojoules per mole, we divide by 1000:

k = 8.314 J/(mol·K) = 0.008314 kJ/(mol·K)

Now, we need to convert the temperature to Kelvin (K) since the Boltzmann constant is defined in Kelvin. To convert from Celsius to Kelvin, we add 273.15 to the temperature:

T(K) = 75°C + 273.15 = 348.15 K

Finally, we can calculate the thermal energy using the formula:

Thermal energy = k * T

Thermal energy = 0.008314 kJ/(mol·K) * 348.15 K

Thermal energy ≈ 2.894 kJ/mol

Therefore, at 75°C, the approximate thermal energy of molecules is approximately 2.894 kilojoules per mole (kJ/mol).

The heat capacity of one mole of water is approximately 75.29/1000 = 0.07529 kj/mol. This value represents the approximate thermal energy in kj/mol of water molecules at 75 ° C.

Thermal energy refers to the energy present in a system that arises from the random movements of its atoms and molecules. When a body has a temperature of 75 ° C, it has a thermal energy that depends on the type of molecules in it and their specific heat capacity.

In this context, we will consider the thermal energy in kj/mol of molecules at 75 ° C.Let's use water as an example to calculate the approximate thermal energy in kj/mol of molecules at 75 ° C. The specific heat capacity of water is 4.18 J/g °C, and the molar mass of water is 18.01528 g/mol. Therefore, the thermal energy in kj/mol of water molecules at 75 ° C can be calculated as follows:ΔH = mcΔt, whereΔH = thermal energy,m = mass of the sample,c = specific heat capacity of the sample,Δt = change in temperature

The straight dough method of bread making is not dependent on the length of time the dough sits to rise. This method involves combining all the ingredients, including the yeast, in one mixing bowl and kneading the dough until it is smooth and elastic.

The dough is then set aside to rise once, for a specific amount of time, usually around an hour or until it has doubled in size. After the first rise, the dough is shaped into loaves or rolls and left to rise again before baking.

In contrast, the sponge dough method involves creating a starter dough, or "sponge," which is left to ferment for a longer period of time, up to 24 hours, before being incorporated into the final dough. The continuous method involves a constantly fermenting dough, while the prime bake method skips the rising process altogether by using chemical leaveners such as baking powder or baking soda.

Expressing the answer in three significant figures separated by a comma, we get: F⃗ _3 = (-7.99, -6.00) N = (-10.00 N, -38.88°) using newton second law.

To find the third force, we can use Newton's second law, which states that the net force on an object is equal to its mass times its acceleration:

F⃗ _net = m⃗ a⃗

where F⃗ _net is the vector sum of all the forces acting on the object.

We can start by finding the vector sum of F⃗ _1 and F⃗ _2:

F⃗ _1 + F⃗ _2 = (3.06 N)x^ + (-1.62 N)x^ + (1.73 N)y^

= (1.44 N)x^ + (1.73 N)y^

Now, we can find the net force by subtracting the vector sum of F⃗ _1 and F⃗ _2 from the mass times acceleration:

F⃗ _3 = m⃗ a⃗ - (F⃗ _1 + F⃗ _2 )

= (6.10 kg)(1.31 m/s^2 x^ - 0.673 m/s^2 y^) - (1.44 N)x^ - (1.73 N)y^

= (7.99 N)x^ - (6.00 N)y^

Therefore, the third force F⃗ _3 has a magnitude of 10.00 N and is directed at an angle of 38.88 degrees below the positive x-axis:

|F⃗ _3| = √[(7.99 N)^2 + (-6.00 N)^2] = 10.00 N

θ = tan⁻¹(-6.00 N / 7.99 N) = -38.88° (measured below the positive x-axis)

Expressing the answer in three significant figures separated by a comma, we get:

The velocity at which an electron will have a de Broglie wavelength of 1.00 m is approximately 1.23 x 10⁶ m/s.

According to de Broglie's equation, the de Broglie wavelength (λ) of a particle is inversely proportional to its momentum (p). The equation is given by λ = h / p, where h is the Planck's constant.

To find the velocity (V) at which the electron has a wavelength of 1.00 m, we need to determine the momentum of the electron. Since the momentum (p) is equal to the mass (m) multiplied by the velocity (V), we can rearrange the equation as p = mV.

Plugging this into the de Broglie equation, we have λ = h / (mV). Solving for V, we get V = h / (mλ).

Substituting the given values of Planck's constant (h = 6.626 x 10⁻³⁴ J·s) and the de Broglie wavelength (λ = 1.00 m), and considering the mass of an electron (m ≈ 9.109 x 10⁻³¹ kg), we can calculate V as approximately 1.23 x 10⁶ m/s.

The color light that refracts the most when entering crown glass from air at some incident angle θ with respect to the normal is (a) violet.

The phenomenon of refraction occurs when light travels from one medium to another, and the change in the medium causes the light to bend. The extent of bending depends on the refractive index of the medium, which varies with the wavelength of light.

In general, the refractive index of a material is higher for shorter wavelengths (higher frequencies) of light and lower for longer wavelengths (lower frequencies). This property is known as dispersion. When light passes through a prism or enters a medium such as glass, different colors of light with different wavelengths are separated due to their varying refractive indices.

For crown glass, the refractive index decreases with increasing wavelength. Therefore, violet light, which has the shortest wavelength among the given colors (violet, blue, green, yellow, and red), will experience the highest refractive index and bend the most when entering crown glass from air at a given incident angle θ.

Hence, the color light that refracts the most in this scenario is (a) violet.
