We can look at this problem as a triangle, r is the hypotenuse so if we take the square root of 6^2+8^2 we get 10

When a typical comet in the Oort cloud is only 1 km in diameter, then the mass of the Oort cloud is changes to  4.18×10⁹ kg.

The mass of each comet int he Oort cloud is,

mass = density × Volume

volume of sphere = 4/3(π×r²) where, r = radius of the sphere

From the given,

diameter = 1 km

radius = Diameter / 2 = 1/2(D)

Volume of the comet = 4/3 (π×r²) = 4/3 (π× (1/2 (10)³)²)

                                   = 4/3×(π) ×(1/8×10⁶)

Mass = density  × volume, where density = 1000 kg/m³

         = 1000  × 4/3×(π) ×(1/8×10⁶)

        = 4.18 ×10⁹ kg

When the typical comet in the Oort cloud is only 12 km in diameter the mass of Oort cloud is 4.18×10⁹ kg.

just use y = mx + b to create an equation of the line in the graph.

then you can plug in 15 for x and then convert 1.5 hours into minutes and plug it in as well.

you dont even need to make an equation for a line. just add 0.2 for every 3 mins.

at 9, it's 0.6, so at 12 it would be 0.8, and then 15 it would be 1.0.

go again all way for 1. 5 hours.

the slope is 0.1/1.5 so you equation would be y = 0.1/1.5x

the slope is rise/run.

Answer:

the answer to your question is false.

Answer:

The solution is given below

Explanation:

The computation is shown below:

Given that

Mass of plane, m is 631 g = 0.631 Kg

The Time period for one circle is 2.15 s

The Radius of circle = 0.95 m

Now the velocity of the plane, v = rω

where,

angular velocity, ω = (θ ÷ t)

For one complete circle, θ = 2π

and Time period T is provided = 2.15 s

Thus, ω = 2π ÷ T = 2π  ÷ 2.15

So, velocity, v = rω

= r × ( 2π  ÷ 2.15 )

= 0.95 × (2π ÷2.15)

= 2.776 m/s

The Acceleration of the plane, a = rω^2

= 0.95 × (2π ÷ 2.15)^2

= 8.114 m/s^2

The Net force acting upon the plane, F = Centripetal force i.e.

= mv2 ÷  r

F = mv2 / r

= (0.631 × 2.7762) ÷ 0.95

= 5.118 N

It takes less effort to lift a piano with a pulley. If the piano is lifted 3 meters, then the distance traveled by the load is 3 m.

Output force is the force exerted on an object by a simple machine.

If the output force is greater than the input force, the mechanical advantage is greater than 1.

The mechanical advantage ratio is output force divided by input force. The larger the mechanical advantage, the easier it is to do work.

Mathematically, the output force of a simple machine is given as;

output force = load x distance moved by load

Thus, it takes less effort to lift a piano with a pulley. If the piano is lifted 3 meters, then the distance traveled by the load is 3 m.

  K = 1.6 10⁻¹⁵ J

Explanation:

In an electron microscope, electrons are used to form images, these electrons are accelerated in electric fields so that they have a kinetic energy that allows obtaining a good amplification with the microscope.

electrical potential energy is converted to kinetic energy

                U = K

                e V = ½ m v²

                v = √2eV /m

the wavelength of these electrons we obtain from the de Broglie equation

                λ = h / p

p = mv

               λ = h / mv

               λ = h / mra 2eV / m

               λ = h / ra 2eVm

where we can see that as the potential energy increases, it electrifies the shorter the wavelength of the electrons and consequently the greater the magnification of the microscope

in general these microscopes use from 10000X onwards therefore for this saponification

                K = e V

               K = 1.6 10⁻¹⁹ 10000

1,000 homes when it's spinning.

No homes when it's not spinning.

The number of homes that the wind turbine can carry is 1000 homes

Power is the ratio of work done by an object with respect to time. The unit of power is in Watts (W).

Given the average electrical power usage of an American home to be 2 kW

Since 1kW = 100W

Average power per American home = 2000W = 2 * 10³Watts

Average power of a turbine = 2MW = 2 * 10⁶Watts

Number of homes that the wind turbine can carry = \(\dfrac{2 \times 10^6}{2 \times 10^3}\)

Number of homes that the wind turbine can carry = \(\dfrac{10^6}{10^3}\)

This shows that the number of homes that the wind turbine can carry is 1000 homes

The magnitude of the tension in the rope is 12.2625 N, and the rope is being pulled horizontally to the left by the wind force..

What is tension?

Tension is the force transmitted through a string, rope, cable or wire when it is pulled tight by forces acting on it from opposite ends. It is a force that is directed along the length of the string, rope, cable or wire and is always directed away from the object that is creating the tension.

When an object is suspended from a rope or cable, the tension in the rope or cable must be equal to the weight of the object in order for the object to remain stationary or move at a constant velocity. If the tension is less than the weight of the object, the object will fall, and if the tension is greater than the weight of the object, the object will rise.

Tension plays an important role in many areas of physics and engineering, such as in the design of suspension bridges, elevator systems, and the motion of satellites in orbit.

To find the tension in the rope and the rope's angle from the vertical, we can start by drawing a free body diagram of the object:

       Tension (upwards)

                   |

                   |

                   |

                   |

        Weight (downwards)

                   |

                   |

                   |

                   |

Wind force (to the right)

where Tension is the tension in the rope, Weight is the weight of the object, and Wind force is the horizontal force due to the wind.

The object is in equilibrium, so the net force on it is zero. We can write two equations based on the forces in the vertical and horizontal directions:

Vertical equilibrium:

             Tension - Weight = 0

                Tension = Weight

Horizontal equilibrium:

   Wind force = Tension * sin(theta)

where theta is the angle between the rope and the vertical.

We can solve these equations for the tension and theta:

Weight = m * g = 1.25 kg * 9.81 m/s^2 = 12.2625 N

Tension = Weight = 12.2625 N

sin(theta) = Wind force / Tension = 18.3 N / 12.2625 N = 1.492

Since sin(theta) is greater than 1, there is no solution for theta. This means that the rope is not making an angle with the vertical, and is instead being pulled directly to the left by the wind force.

Therefore, the magnitude of the tension in the rope is 12.2625 N, and the rope is being pulled horizontally to the left by the wind force.

Answer:

Explanation:

According to Newton's Law of Gravitation, the gravitational force between two objects is always mutual, meaning that the force that one object exerts on the other is equal in magnitude but opposite in direction.

This means that if planet A exerts a gravitational force on planet B, then planet B will also exert a gravitational force on planet A. The magnitude of this force will be equal to the magnitude of the force that planet A exerts on planet B, but the direction will be opposite.

For example, if planet A exerts a gravitational force on planet B that is pulling planet B towards planet A, then planet B will also exert a gravitational force on planet A that is pulling planet A towards planet B. The magnitude of these two forces will be equal, but the directions will be opposite.
