what is the magnitude of the resulting force on the 8 kg mass at the origin? the value of the universal gravitational constant is 6.6726 × 10−11 n · m2 /kg2 . answer in units of n.

Answers

Answer 1

As per the details given, the magnitude of the resulting force on the 8 kg mass at the origin due to the gravitational attraction of the other two masses is 1.09 x 10⁻¹¹ N.

To calculate the magnitude of the resulting force on the 8 kg mass at the origin, we need to consider the gravitational forces exerted by the other two masses.

Let's assume the mass at the origin is M₁ = 8 kg, the mass at (0, 6) is M₂ = 16 kg, and the mass at (8, 0) is M3 = 4 kg.

The gravitational force (F) between two masses M₁ and M₂ is given by Newton's law of universal gravitation:

F = G * (M₁ * M₂) / r²

where G is the universal gravitational constant (6.6726 × 10⁻¹¹ N·m²/kg²), M₁ and M₂ are the masses, and r is the distance between the centers of the masses.

1. Gravitational force between M₁ and M₂:

Distance between M₁ and M₂:

r1 = √(0² + 6²) = 6 m

Gravitational force between M₁ and M₂:

F1 = G * (M1 * M2) / r₁²

F1 = 6.6726 × 10⁻¹¹ * (8 kg * 16 kg) / (6 m)²

F1 ≈ 1.0660 × 10⁻¹⁰ N

2. Gravitational force between M₁ and M₃:

Distance between M₁ and M₃:

r₂ = √(8² + 0²) = 8 m

Gravitational force between M₁ and M3:

F₂ = G * (M₁ * M₃) / r₂²

F₂ = 6.6726 × 10⁻¹¹ * (8 kg * 4 kg) / (8 m)²

F₂ ≈ 2.0015 × 10⁻¹¹ N

Now, the resulting force on M₁ is the vector sum of the forces F₁ and F₂. Since the forces are acting along the x-axis and y-axis, we can use the Pythagorean theorem to find the magnitude of the resulting force:

Magnitude of the resulting force on M1:

F' = √(F₁² + F₂²)

F' = √((1.0660 × 10⁻¹⁰ N)² + (2.0015 × 10⁻¹¹ N)²)

F' ≈ √(1.1363 × 10^(-20) N² + 4.0060 × 10⁻²² N²)

F' ≈ √(1.1769 × 10⁻²⁰ N²)

F' ≈ 1.09 × 10⁻¹¹ N

Thus, the resulting force on the 8 kg mass at the origin is approximately 1.09 × 10⁻¹¹ N.

Answers

A rigid assembly consists of three identical uniform bars with an extra mass attached to one of them and the system's angular momentum is zero between locations A and B.

The rigid assembly conserves angular momentum because it can freely spin in the vertical plane about the point connecting the bars. Unless an external tension is applied, angular momentum, a vector quantity, is conserved.

The assembly's initial angular momentum is zero when it is in position A of rest since its linear momentum and distance from the axis of rotation are also zero.

Because there is no external torque operating on the system, when the extra mass experiences very little disturbance and the assembly moves to position B, its angular momentum stays constant.

As a result, the system's angular momentum is zero between locations A and B.

Answers

The combined effects of electrical forces and concentration differences across the membrane.

Since there are less positive ions within the cell due to the ion gradient, the interior is negative in comparison to the exterior forces. The ensuing membrane potential favors positively charged ions entering the cell and negatively charged ions exiting the cell. A combination of a concentration gradient and an electrical field gradient, the electrochemical gradient controls the direction in which ions will flow through an open ion channel. These two gradients may be taken into account individually. Energy can be released when the ions return down their electrochemical gradients, which primary active transport creates. The energy stored in these gradients is used in secondary active transport to move other materials against their own gradients.

Answers

The amount of work done in emptying the tank by pumping the water over the top edge is 163.01* 10³ ft-lbs.

Given that, the tank is 8 feet across the top and 6 feet high

By the property of similar triangles, 4/6 = r/y

6r = 4y

r = 4/6*y = 2/3*y

Each disc is a circle with area, A = π(2/3*y)² = 4π/9*y²

The weight of each disc is m = ρw* A

m = 62.4* 4π/9*y² = 87.08*y²

The distance pumped is 6-y.

The work done in pumping the tank by pumping the water over the top edge is

W = 87.08 ∫(6-y)y² dy

W = 87.08 ∫(6y³ - y²) dy

W =  87.08 [6y⁴/4 - y³/3]

W =  87.08 [3y⁴/2- y³/3]

The limits are from 0 to 6.

W =  87.08 [3*6⁴/2 - 6³/3] = 87.08* [9*6³ - 2*36] = 87.08(1872) = 163013.76 ft-lbs

Answers

The period calculated by Student a is more accurate because digital stopwatches are more precise and accurate than analog wristwatches.

What is stopwatch?
A stopwatch is a type of timepiece made to count the seconds between activation and deactivation. A stop clock is a sizable digital stopwatch made for distant viewing, such as in a sports stadium. In manual timing, a button is pressed to start and stop the clock. In a fully automatic time, sensors automatically trigger both starting and stopping. Two buttons just on case are typically used to operate the timing functions. The timer starts when the top button is pressed, and it stops when the button is pressed a second time, leaving the displayed elapsed time.

Digital stopwatches have the ability to measure time to the hundredth, or even thousandth, of a second, while analog watches measure time in seconds, minutes, and hours. The increased precision of the digital stopwatch will give a more accurate period for the pendulum oscillations.'

a certain camera lens has a focal length of 175 mm. its position can be adjusted to produce images when the lens is between 180 mm and 210 mm from the plane of the film. over what range of object distances is the lens useful?

Answers

The useful range of object distances of the lens is 1.05 m and 6.3 m.

Focal length of the camera = 175 mm

Distance of Image 1 = i₁ = 180 mm

Distance of Image 2 = i₂ = 210 mm

Since the distance between the images is positive, hence we get real images.

Using thin lens equation,

= (1/f) = (1/i) + (1/o)

For image 1,

= (1/o₁) = (1/f) - (1/i₁)

= (1/o₁) = (1/175) - (1/180)

= o₁ = 6299.4 mm = 6.3 m

Similarly for image 2,

=  (1/o₂) = (1/f) - (1/i₂)

=  (1/o₂) = (1/175) - (1/210)

= o₂ = 1050 mm = 1.05 m

By focusing a laser on the surface of a asteroid, the intense surface heating from the laser could cause surface material to be ejected into space at high speed due to change in the momentum

Since the surface material is ejected into space at high speed, it has significant momentum. And since the asteroid and all of its component are considered as an isolated system, the total momentum is conserved according to law of conservation of momentum.

So, as the surface material is ejected with momentum, this causes a change in the momentum of the asteroid in the opposite direction.

In physics, a gravitational field is a model used to describe the effect of a massive object extending into the space around it and creating a force on another massive object. Gravitational fields are therefore used to describe gravitational phenomena and are measured in Newtons per kilogram (N/kg). It is therefore measured in square meters per second (m/s2).

In the original concept, gravity was the force between point masses. Borrowing from Isaac Newton, Pierre-Simon Laplace attempted to model gravity as a kind of radiation field or fluid. Since the 19th century, explanations of gravity have usually been taught in terms of field models rather than point attraction

In the field model, instead of two particles attracting each other, the particles distort space-time with their mass. This distortion is perceived and measured as a 'force' that moves in a certain way depending on the curvature of spacetime. And either gravity doesn't exist or gravity is an imaginary force.

1) why is star formation more likely to occur in cold molecular clouds than in regions where the temperature of the interstellar medium is several hundred thousand degrees?

Answers

Colder clouds are less resistant to gravity and therefore can collapse more easily because pressure is greater in heat & lower in cold stuff.

What is temperature explain?

Temperature is a unit used to represent hotness or coolness on any of a number of scales, include Fahrenheit and Celsius. Temperature shows the direction of spontaneous heat transfer, which is from a region of high temperature to a cooler body.

What temperature is too hot for humans?

People frequently cite a 2010 study that concluded the highest limit of safety would be a humid temperature of 35 C, or 95 F at 100% humidity or 115 F at 50% humidity.

what range of spring constant values will cause the motion of the system to have damped oscillation?

Answers

The range of spring constant values is less than 2√Km that will cause the motion of the system to have damped oscillation is given.

[tex]\beta =\left \{ {{y=2\sqrt{km} } \atop {y > 2\sqrt{km} }} \right.[/tex]

[tex]\beta =\left \{ {{b\leq 2\sqrt{Km}----under-damping }[/tex]

When b≤ 4mk, the damping constant, is low, the system oscillates while the motion's amplitude decays exponentially. Then this system is underdamped.After displacement, a body will oscillate on its own accord at its natural frequency. However, as the oscillation continues to lose amplitude, it eventually comes to an end.

Non-conservative forces like friction within the oscillation system are what lead to the decrease in amplitude. The term "dissipative forces" also refers to the non-conservative forces.

The oscillations eventually stop if the friction between the box's surface and the floor is not ignored. The force that dampens the oscillation is referred to as the damping force.

is only capable of pushing a car with a force of 800 n. how fast must the car be moving at the bottom of the hill so that his 800 n force will be just enough to get it to the top of the hill

Answers

It will depend on your frame of reference, assuming no energy is lost in the conversion of energy to motion.

Newton's first law asserts that an object in motion will remain in motion until acted on by a force. The car will remain in motion as long as the forces on it are balanced. However, we currently consider a motion to be moved relative to a frame of reference; depending on your perspective, the car could be traveling forward, backward, or not moving at all.

An external force is described as a change in mechanical energy, which can be either kinetic or potential energy in an item. External agents cause these forces. Friction, normal force, and air resistance are examples of external forces. Because stationery is simply a constant speed of 0. So the pace is constant.
