The largest moon in the solar system is Ganymede, a moon of Jupiter. Ganymede orbits at a distance of 1.07×109m from the center of Jupiter with an orbital period of about 6.18×105s. Find the mass of Jupiter.

Answers

Answer 1

The moon of Jupiter, Ganymede is the largest moon in the solar system. The mass of Jupiter when the orbital period and the distance from the centre of the orbit are given is calculated to be 1.57 × 10²⁷ kg.

The time required to complete one revolution in an orbit around the planet is known as the Orbital Time period of motion. The orbital distance's cube is directly proportional to the square of the time period.

Given that,

Orbital distance R = 1.07 × 10⁹ m

Time period T = 6.18 × 10⁵ s

We know the formula of time period as,

T² = 4 π² R³/ G M

where, M is the mass of Jupiter

G is the gravitational constant

(6.18 × 10⁵)² = 4 π² (1.07 × 10⁹)³/(6.67 × 10⁻¹¹) M

Making M as subject, we have,

M = 4 π² (1.07 × 10⁹)³/[ (6.67 × 10⁻¹¹) (6.18 × 10⁵)²] = 1.57 × 10²⁷ kg

An amusement park ride consists of a rotating circular platform 7.4 m in diameter from which 10 kg seats are suspended at the end of 1.81 m massless chains. When the system rotates, the chains make an angle of 26.6 degree with the vertical. The acceleration of gravity is 9.8 m/sa). what is the speed of each seat? answer in units of m/sb). if a child of mass 49.1 kg sits in a seat, what is the tension in the chain ( for the same angle)? answer in units of N

Answers

The speed of each seat is 4.71 m/sec, if the radius of the rotating platform is 3.7 meter. If a child of 49.5 kg sits in a seat, then the tension in the chain will be 648.4 N.

Mass of each seat, m = 10 kg

Radius of the rotating platform, R = 7.4/2 = 3.7 m

Let the tension in the chain = T₁

Vertical angle made by the chain = 26.6°

There will be two components of the tension in chain. Vertical component of the chain will be balanced by the weight(mg) of the seat.

T×cos26.6 = 10 ×9.81

T = (10×9.81)/cos26.6

T = 109.7 N

Horizontal component of the tension in chain is balanced by the centrifugal force due to the circular motion of radius,

R₁ =  3.7 + 1.81×sin26.6

R₁ = 4.51 m.

Centrifugal force, F = mv²/R₁

(10×v²)/4.51 = 109.7 × sin26.6

(10×v²)/4.51 = 49.12

v² = (49.12 × 4.51)/10

v = 4.71 m/sec

If a child of mass 49.1 sits on the seat, then the total weight on the seat will be, W = (10+49.1) × 9.81 = 579.77 N

This weight will be balanced by the vertical component of the tension in the chain,

579.77 = T×cos26.6

T = 579.77/cos26.6

T = 648.4 N

The mass of the load is 50,000N/m multiplied by 10.0cm, which is 500,000N.

Hooke's law states that the force (F) required to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, Fs = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness) and x is small in comparison to the total possible deformation of the spring.

B. Using Hooke's law, F = kx, where F is the force of the truck's hock, k is the spring constant, and x is the compression of the hock. Rearranging for mass, m = F/g, where g is the acceleration due to gravity. Thus, m = kx/g, or m = (50,000N/m * 10.0cm)/9.8m/s^2, which yields 500,000N.

Heavy elements, such as gold, silver, and mercury, as well as the elements that make up the earth's core, such as iron and nickel, originated in the hearts of stars. They were created through the process of nuclear fusion, which occurs when the temperatures and pressures inside a star are high enough to overcome the electrostatic repulsion between the positively charged nuclei of atoms.

What are  heavy element?

When fusion occurs, the nuclei of the atoms merge, creating a new, heavier element. This process is called nucleosynthesis. The fusion of lighter elements, such as hydrogen and helium, produces heavier elements, such as carbon, oxygen, and neon.

Therefore, most heavy elements, such as gold and platinum, are created in supernovae, massive explosions that occur when the fuel in a star runs out, and the star collapses under its own gravity.

The force of drag acting on the skydiver is 795 N upwards.

When a parachutist jumps from a plane, only one force is acting on him, namely the force of gravity (the weight of the parachutist) so that the parachutist moves down. When jumping from a height when parachuting, the force of gravity will pull us down very quickly. Thus, we will freefall very quickly

Given in the questions: Constant velocity = 54.4 m/s

According to Newton's first law, when the net resultant force on an object is 0, the object is moving at a constant speed or is at rest and remains at rest. So, we know the resultant force is 0.

Now we use Newton's second law.

Resultant force = ma

Efficiency of a machine if energy input is 7.55 and energy output is 5.05

Answers

The efficiency of this machine is 66.67%.

What is efficiency?

Efficiency is a measure of how well a machine or system is able to convert input energy into useful output energy. It is a ratio of the output energy to the input energy, expressed as a percentage.

An efficient machine or system is one that is able to convert a large portion of the input energy into useful output energy, with minimal energy loss. Conversely, an inefficient machine or system is one that loses a significant portion of the input energy as waste heat, sound, or other forms of energy that are not useful to the desired output.

The efficiency of a machine can be calculated using the formula:

Efficiency = (Energy Output / Energy Input) x 100%

In this case, the energy input is 7.55 and the energy output is 5.05, so we can calculate the efficiency as follows:

Efficiency = (5.05 / 7.55) x 100% = 66.67%

If g, M, and R are the parameters of planet 1, let's say g', m, and r are the parameters of planet 2. So,

m = 2Mr = 2R

The acceleration due to gravity on planet 2 is

g/g' = (GM/R²)/(Gm/r²)

g/g' = (M/R²)/(m/r²)

g/g' = Mr²/mR²

g/g' = M(2R)²/(2M)R²

   C = λ f  

   (3x10^8 m/s) = λ (1. 5 x 10^15 sec^-1)

   λ =     (3x10^8 m/s)/(1. 5 x 10^15 sec^-1)

A cyclist is rounding a 20-m radius curve at 12 m/s. What is the minimum possible coefficient of static friction between the bike tires and the ground?

Answers

The minimum possible coefficient of static friction between the bike tires and the ground is 0.734.

The minimum possible coefficient of static friction is that at which the moving object is on the verge of the stopping state.

Radius of the curve, (R) = 20 m.

Velocity of the cyclist, (v) = 12 m/sec

g = 9.81 m/s²

On a circular curve, the cyclist will experience the centrifugal force(F) which acts outwards. This force is,

F = mv²/R

This centrifugal force(F) is balanced by the static friction force(Fₓ). Which is,

Static friction force = mg × coefficient of static friction(Ц)

mv²/R = mg × coefficient of static friction(Ц)

coefficient of static friction(Ц) = v²/gR

The torque about the pivot is positive, after the push has ended the ball's angular velocity will hold steady, right after the push has ended the torque would be zero.

Torque is a measure of force that can rotate an object around a fixed axis. as the ball is moving in the same direction in which the force is applied. So the torque will be positive. After the push has ended the ball will continue to rotate at the constant angular velocity, as the pivot is frictionless, so no opposing force will decrease the angular velocity of the ball. So the ball's angular velocity will hold steady.

After the push has ended, the torque will be zero. Torque is defined as follows:

Torque = force × distance from the rotation axis

The distance a car will travel in 3 s if it's acceleration was 5 m/s² is 22.5m and is denoted as option B.

What is Acceleration?

This is defined as the rate at which velocity changes with time and is usually in terms of both speed and direction which makes it a vector quantity.

Acceleration = velocity / time

5 m/s² = v / 3s

v = 15m/s.

To calculate the distance we can use:

D = 1/2*a*t²

 =  1/2 × 5 × 3²

= 22.5m.

A mass on a spring undergoes simple harmonic motion. When the mass passes through the equilibrium position, its instantaneous velocity.

Answers

A mass on a spring undergoes simple harmonic motion. When the mass passes through the equilibrium position, its instantaneous velocity is maximum.

Simple harmonic motion or SHM is the alternating motion of an object that passes through a certain balance point. SHM has a fixed frequency and amplitude and is periodic, namely movements that occur regularly and are repeated at the same time.

When a spring undergoes simple harmonic motion, the mass accelerates in a direction toward the equilibrium point, then the velocity of the object at the equilibrium point is maximum. The object is accelerating in a direction toward the equilibrium point. Acceleration caused by the force recovered.

The maximum force that can be put on an egg without breaking it has been determined to be 15 N. If the 0.15 kg egg is moving at 10.0 m/s and needs to be brought to a stop. How much time will need to be allowed for it to slow down?

Answers

The time it takes to put the egg to rest is 0.1 seconds

What is time?

Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present.

To calculate the time it will takes to put the egg to rest, we use the below.

Formula:

t = m(v-u)/F.................... Equation 1

Where:

t = Timem = Massv = Final  Velocityu = Initial velocityF = Force

From the question,

Given:

m = 0.15 kgF = -15 N (Against the direction of motion)u = 10 m/sv = 0 m/s (To rest)

Substitute these values into equation 1

t = 0.15(0-10)/-15t = -1.5/-15t = 0.1 seconds

Hence, the time is 0.1 seconds

Please help chemistry, I'm stuck
9 mol P4010 forms 36 mol H3PO4, while
51 moles H2O form 34 moles H3PO4.
How many moles of H3PO4 form during
the reaction?
? ] mol H3PO4
Round your answer to the ones place.

Answers

Answer:

???

Explanation:

Not sure to which reaction the question refers

 but here is the simplest balanced equation

    P4 O10     +  6  H2 O ======>  4  H3 PO4  

So the answer may be   4 moles

If the reaction is using 9 moles of PO4   and 51 Moles of H2O

  the H2O will limit the number of moles of H3PO4 produced to 34 moles      this may be the answer the Q is looking for....H2O is the limiting reagent

The number of moles of H3PO4 form during the reaction is 4.

What is meant by limiting reagent ?

Limiting reagent of a reaction is defined as the reactant that is being completely used up in the reaction.

Here,

Given that,

The number of moles of P₄O₁₀ = 9

The number of moles of H₂O = 51

If 9 moles of P₄O₁₀ can form 36 moles of H₃PO₄, 1 mole of P₄O₁₀ can form 36/9 = 4 moles of H₃PO₄

The balanced equation for the reaction can be written as,

P₄O₁₀ + 6H₂O ⇒ 4H₃PO₄

From the equation, we can say that 1 mole of P₄O₁₀ and 6 moles of H₂O will form 4 moles of H₃PO₄

H₂O is the limiting reagent of this reaction.

Hence,

The number of moles of H3PO4 form during the reaction is 4.
