According to the data given in the question the net force on the box is of 5 N.

All of the forces that are applied to an object are added up to form the net force. As a consequence of the fact that it (force) is a vector and therefore that two forces with identical magnitudes and opposing directions cancel each other out, the resultant force is the total of the forces, or put another way, the net force is just the total of all the forces.

Given data :

Force on box to the left side (F1) = 15 N

Force on box to the right side (F2) = 20 N

Because both forces are in opposite direction

Hence,

Net force = F2 - F1

Net force = 20 - 15

Net force = 5 N.

Answer:

To solve this problem, you can use the principle of transverse static equilibrium. This states that the sum of the forces acting on an object must be equal to zero for the object to be in equilibrium. In this case, the forces acting on the rod are the tension in the strings, the weight of the rod, and the weight of the masses hung on the rod.

First, you can find the weight of the rod by multiplying its mass by the acceleration due to gravity:

Wrod = mrod * g

= 0.7 kg * 9.8 m/s^2

= 6.86 N

Next, you can find the weight of the 4.0-kg mass by multiplying its mass by the acceleration due to gravity:

W1 = m1 * g

= 4.0 kg * 9.8 m/s^2

= 39.2 N

You can find the weight of the 2.0-kg mass in the same way:

W2 = m2 * g

= 2.0 kg * 9.8 m/s^2

= 19.6 N

To find the tension in the strings, you can use the principle of transverse static equilibrium. The forces acting on the rod are the tension in the strings, the weight of the rod, and the weight of the masses hung on the rod. You can represent these forces as vectors acting at the points where the strings are attached to the rod. The vectors representing the tension in the strings will be equal in magnitude but opposite in direction. The vectors representing the weight of the rod and the masses will act vertically downward.

The destructive interference formula for diffraction grating problems is \(d sin \theta = (n+\frac{1}{2})\lambda\).

Destructive interference happens when the maxima of two waves are 180° out of phase a positive displacement of one wave is canceled exactly by a negative displacement of the other wave.

The formula for brighter patches resulting from constructive interference and darker patches resulting from destructive interference in a diffraction grating is:

\(\rm d sin \theta = n \lambda\)

The grating spacing is denoted by d, the angle of light is denoted by a the fringe order is denoted by n, and the wavelength is denoted by \(\rm \lambda\).

The destructive interference formula is now based on the fact that destructive interference occurs between the fringes.

Hence the destructive interference formula for diffraction grating problems is \(d sin \theta = (n+\frac{1}{2})\lambda\).

Explanation:

It will take about 12.12 minutes for the thermocouple to read 95% of the initial temperature difference of the sphere. This is due to difference in temperature.

What is the time required to read 95% of initial temperature difference?

In order to determine how long it will take for the thermocouple to read 95% of the initial temperature difference, the following formula is used:

t = (rho × V × Cp)/(h × pi × D) × ln ((Tinitial - T∞) / (Tinitial - Tcutoff))

where, t = time (s), ρ = density (kg/m³), V = volume (m³), Cp = specific heat capacity (J/kg °C), h = heat transfer coefficient (W/m²°C), D = diameter (m), Tinitial = initial temperature (°C), T∞ = surrounding temperature (°C), Tcutoff = temperature at which the thermocouple reading is 95% of the initial temperature difference (°C).

Substituting the given values into the above formula:

t = (8500 kg/m³ × (4/3 × pi × (0.0006 m)³)) / (65 W/m2 °C × pi × 0.0012 m) × ln ((100 °C - 25 °C) / (100 °C - 95 °C))

t = 727.31 s or 12.12 minutes.

Therefore, it will take approximately 12.12 minutes for the thermocouple to read 95% of the initial temperature difference.

Answer:

a)     1: 100  F₂ = 100 F₁,  b) P₁ = P₂   1:1

Explanation:

The pressure in a system is the same for a given horizontal line, therefore

          P₁ = P₂

where subscript 1 is for small piston and index 2 is for large piston 2

a) they ask the relation of the forces

pressure is defined by

        P = F / A

for the small piston

        P₁ = F₁ / A₁

the area of ​​the piston is

        A₁ =π r₁²

        P₁ = F₁ /π r₁²

for big piston

         P₂ = F₂ / A₂

in the exercise indicates that the diameter of the large piston is 10 times the diameter of the small piston

         A = π r₂²

         r₂ = 10 r₁

          r₂ = π 10² r₁²

we substitute

         P₂ = \(\frac{F_2}{ \pi \ 100 \ r_1^2}\)

we equalize the pressures

          \(\frac{F_1 }{ \pi \ r_1^2 } = \frac{F_2}{ \pi \ 100 r_1^2}\)

           F₁ = F₂ / 100

            F₂ / F₁ = 100

therefore the force ratio is

             1: 100

b) according to Pascal's principle for the same height the pressure is the same regardless of the shape of the container, therefore the pressure of the two pistons is the same

The earth is actually neutral in nature. If a positive charged body is connected to the earth, the positive charge will be drained to the ground. This can be clearly described that, when the surface of earth becomes positively charged, there occurs a potential difference between the surface and the ground.

As a result, the electrons flows from the ground to the surface. The negative charge and positive charges cancels each other and thus neutralizing the surface.

Explanation:

Due to the fact that the gravitational force is inversely proportional to the mass of the two interacting objects, heavier objects will be drawn together by a stronger gravitational attraction. As a result, the gravitational pull between two objects grows as their respective masses rise.

Since the gravitational force is exactly proportional to the mass of both interacting objects, heavier items will be attracted by stronger gravitational forces. Therefore, the gravitational attraction between two objects grows as their respective masses do as well.

The attraction created by gravity is between masses. The gravitational force, commonly known as the gravity force, increases with the size of the masses. With an increase in the distance between masses, the gravitational pull rapidly lessens.

NEOs, or Near-Earth Objects, refer to asteroids and comets that have orbits that bring them close to Earth. These objects are of great interest to scientists and astronomers due to the potential threat they pose to our planet in the event of a collision. NEOs can be composed of rock, metal, ice, and dust, depending on whether they are asteroids or comets.

Asteroid 2004 FH, which passed within a tenth of the Earth-Moon distance in March 2004, was classified as a NEO. Its classification was based on the discovery that its period, or the time it takes to complete one orbit around the Sun, was about nine months. This close encounter with Earth and its relatively short period made it fall under the category of NEO.

NEOs are further classified into different groups based on their orbits. These classifications include Atens, Apollos, and Amors. Atens have orbits that primarily fall within the orbit of Earth, Apollos have orbits that cross Earth's orbit, and Amors have orbits that are mostly outside Earth's orbit but can still come close to our planet.

The formula for calculating the equivalent resistance (R_eq) of resistors connected in parallel is given by:

\(\frac{1}{R_{\text{eq}}} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3} + \ldots\)

In this case, we have three resistors connected in parallel, each with a resistance of 10^12 ohms. Substituting the values into the formula, we can calculate the equivalent resistance:

\(\frac{1}{R_{\text{eq}}} = \frac{1}{10^{12}} + \frac{1}{10^{12}} + \frac{1}{10^{12}}\)

Simplifying the equation, we get:
