A more fundamental way to measure the rotation of Jupiter is to measure the changes in the planet's radio waves, which are controlled by its magnetic field.
Rotation of JupiterJupiter, in contrast to the inner terrestrial planets, is a sphere made almost completely of hydrogen and helium. There are no craters or mountains that spin into view after a set amount of time on Jupiter, unlike Mars or Mercury, which you can follow to determine the rotation speed.Out of all the planets in the Solar System, Jupiter rotates the most quickly. Given that Jupiter is also the largest planet in the Solar System, this is quite an accomplishment because it is rapidly rotating a vast amount of mass. The planet's equator protrudes due to its rapid spin. Jupiter doesn't appear to be a perfect sphere; rather, it resembles a squashed ball. Even with a modest telescope in your backyard, you can see the bulge at the equator.Observing the enormous storms that circle Jupiter's atmosphere can help determine how long it takes for Jupiter to revolve. Monitoring the variations in the planet's radio waves, which are governed by its magnetic field, is a more basic technique to gauge the rotation.

A golf ball is initially travelling at 25m/sec hits a sand traps and slow down with an acceleration of -25m/sec. find its displacement after 2.0 sec.
The displacement of the ball is zero.
What is displacement?
The smallest distance between the initial and final position of an object.
What are the equations of motion?
There are three equations of motion that completely describes the motion of an object.
The first equation of motion gives the relationship between the initial velocity, final velocity, acceleration, and time.
The second equation of motion gives the relationship between the initial velocity, displacement, acceleration, and time.
The third equation of motion gives the relationship between the initial velocity, final velocity, acceleration, and displacement.
Given time, initial velocity, and acceleration, the displacement can be calculated using the second equation of motion. The second equation of motion is,
s=u*t+(1/2)*a*t^2
Here, u=25 m/sec, a=-25 m/sec and t=2.0 sec.
Put the values in the formula and calculate the displacement.

At what distance is the electrostatic force between two protons equal to the weight of one?.
0.118 m is the distance between the two protons.
Mass of proton = 1.6726 × 10⁻²⁷ kg
Weight of proton= 1.6726 × 10⁻²⁷ x 9.81 N
= 1.6408 × 10⁻²⁶ N
Charge of proton = 1.602 × 10⁻²⁹ C
The force between two protons = kq²/r² where, K is a proportionality
constant, q is a charge of proton and
r is the distance between two protons.
= 9 × 10⁹ × (1.602×10⁻¹⁹)²/r²
To calculate distance :
Weight of proton= Force between protons
⇒ 1.6408 × 10⁻²⁶ N = 9 × 10⁹ × (1.602×10⁻¹⁹)²/r²
⇒ r = 0.118m
Therefore, 0.118 m is the distance between the two protons.

In the process of loading a ship, a shipping container gets dropped into the water and sinks to the bottom of the harbor. Salvage experts plan to recover the container by attaching a spherical balloon to the container and inflating it with air pumped down from the surface. The dimensions of the container are 5.80 m long, 2.60 m wide, and 2.80 m high. As the crew pumps air into the balloon, its spherical shape increases and when the radius is 1.50 m, the shipping container just begins to rise toward the surface. Determine the mass of the container. You may ignore the weight of the balloon and the air in the balloon. The density of seawater is 1027 kg/m3.
Answer:
57.885.8 kg weight of the container
Explanation:
The volume of the balloon * density of water = buoyant force of balloon
volume of a sphere = 4/3 pi r^3
= 4/3 pi * (1.5)^3 = 14.14 m^3 <===balloon volume
Now, find the buoyant force on the container ALONE ....
5.8 * 2.6 * 2.8 * 1027 = 43 364 kg <===== buoyant force
Now add the buoyant force of the balloon to find the weight

Scientists in the 1800s suggested that the source of the Sun's energy might be gravitational contraction. What was the major flaw of this hypothesis
Answer:
The major flow of this hypothesis was that the Sun could last only about 25 million years.
Explanation:
Gravitational contraction:
It is the process of a cloud's gravity overcoming its internal pressure and causing a collapse. Before the atoms inside will fuse, the core temperature of an object must reach a minimum temperature.If the source of the Sun's energy is gravitational contraction,
from this process we could say that, the Sun could last only about 25 million years, which is far less than the age of Earth. But geologists already had evidence the Earth was much older than that.

A sphere of diameter 6.0cm is moulded into a thin uniform wire of diameter 0.2mm.calculate the length of the wire in metres.
The length of the wire is 36 m.
The density is the ratio of the mass and volume of a substance. The density is given by the formula,
d=m/V
where d is the density. m is the mass and V is the volume.
The density of the material does not change and the initial and final volume of the substance will be equal when it has changed shape provided the mass has not been changed.
The radius r of the sphere is half of its diameter. Therefore, r=6.0/2 = 3.0 cm.
Then volume of the sphere Vs is given by the formula,
Vs=(4/3)*π*r^3
Put the value of r in the above formula.
Vs=(4/3)*3.14*(3.0)^3
Vs=113.04 cm^3
For the cylinder, the radius s=0.2/2 mm = 0.01 cm and the length l is unknown. The volume of the cylinder Vc is given by the formula,

Given:
A transverse wave on a string has an amplitude "A". A tiny spot on the string is colored red.
To find:
Distance travelled by red spot in one cycle of the wave.
Solution:
So, we know that particles in a transverse wave oscillate periodically in a direction perpendicular to propagation of wave.
Frankly speaking, the type of motion shown by particles is SHM (simple harmonic motion)
So, in a wave cycle, the red dot will start from a particular position and will end at the same position.

What is the magnitude of the net electric field at the origin produced by this distribution of charge?
The magnitude of the net electric field at the origin due to the given distribution of charge is E_net = 4kQ/πR².
Given:
A semi-circle distribution with radius 'r'
Charges '+Q' and '-Q'
Calculation of net electric field:
Step 1:
The electric field for a charge is given as:
E = (kλ/R) i + (kλ/R) j - ( 1 )
where, k is Coulomb's force constant
λ is charge density
R is separation distance between the charges
i & j are unit vectors for x-axis and y-axis respectively
Step 2:
The electric field due to charge +Q is given as:
E₁ = (kλ/R) i - (kλ/R) j - ( 2 )
The electric field due to charge -Q is given as:
E₂ = (kλ/R) i + (kλ/R) j - ( 3 )
Step 3:
Thus, the net electric field will be given as:
E_net = E₁ + E₂
Applying values in above equation, we get:
E_net = (kλ/R) i -(kλ/R) j + (kλ/R) i + (kλ/R) j
=( kλ/R) [ i - j + i + j ]
= 2i (kλ/R) -( 4 )
Step 4:
Now, we know that the linear charge density is given as:
λ = Charge/length
= Q/(πR/2)
= 2Q/πR
Applying the value in equation 4, we get:
E_net = 2i (k(2Q/πR)/R)
= 4i (kQ/πR²)
= 4kQ/πR²
Therefore, the net electric field due to the given charge distribution is of magnitude 4kQ/πR² directed along the positive x-axis.

If this minimum mass is nudged ever so slightly, it will start being pulled up the incline. What acceleration will it have
The acceleration of the mass when it is nudged ever so slightly on the incline: a = (g sin(∅)) - (μ g cos(∅))
If the minimum mass on the incline is nudged ever so slightly, it will experience a force due to gravity pulling it down the incline. This force can be broken down into two components: one parallel to the incline and one perpendicular to the incline.
Since the mass is on an incline, it experiences a normal force that is perpendicular to the incline.
The perpendicular component, also known as the weight component perpendicular to the incline, is given by mg cos(∅).
The force of friction can be represented as the product of the coefficient of friction (μ) and the normal force (mg cos(∅)).
Therefore, the net force along the incline is;
(mg sin(∅)) - (μ mg cos(∅)).
To calculate the acceleration, we use Newton's second law, which states that the net force acting on an object is equal to its mass (m) multiplied by its acceleration (a).
(mg sin(∅)) - (μ mg cos(∅)) = ma
Simplifying:
a = (g sin(∅)) - (μ g cos(∅))
This is the expression for the acceleration of the mass when it is nudged ever so slightly on the incline. The acceleration will depend on the angle of the incline (theta), the coefficient of friction (μ), and the acceleration due to gravity (g).
