Planets after Mars in our solar system are called Jovian planets. Therefore, Jupiter, Saturn, Uranus and Neptune are Jovian planets. The specialty of these planets is that they mostly made of gases and have ring around them.
They have rings around them because tidal forces cause volcanic eruptions on some moons, and part of this material subsequently escaped the gravity of the moons, forming the rings.
The resistors in the circuit below have the following values: R1 = 7.20 Ω, R2 = 7.00 Ω, and R3 = 4.10 Ω. The two batteries each have a voltage of 4.00 V.
The total voltage in the circuit is 8 V. Then, the current passing through the resistor R3 is 1.95 A. The power supply to this resistor by the batteries is 15.6 W.
What is Ohm's' law?According to Ohm's law, the voltage through a closed circuit is the product of the current passing through the circuit and resistance through it.
Hence, V = I R.
Given that the resistance through the resistor R3 = 4.10 Ω
The voltage across each batteries = 4 V
Total voltages = 4 + 4 = 8V
Current = voltage/ resistance
= 8 V/ 4.10 Ω
= 1.95 A.
Power through a circuit is the product of current and voltage through it.
P = I V
Power supplied to R3 = 1.95 A × 8 V = 15.6 W.
Therefore, the power supplied by the batteries to the resistor R3 is 15.6 W.

Then, under the action of the gravity, the chain drop freely. Determine the speed of the chain when the left end of leave the plane.
For the chain: linear density =ρ, length =l. The chain is placed on a smooth plane. The speed of the chain when the left end leaves the plane is the same as its initial speed, which is zero.
What is speed?Generally, To determine the speed of the chain when the left end leaves the plane, we need to consider the forces acting on the chain and use Newton's second law to find the acceleration of the chain.
The forces acting on the chain are the force of gravity and the normal force from the plane. The force of gravity is downward and is equal to the weight of the chain, which is given by the equation:
Fg = mg
where m is the mass of the chain and g is the acceleration due to gravity. The normal force from the plane is upward and is equal to the force of gravity, since the chain is stationary at this moment.
Newton's second law states that the acceleration of an object is equal to the net force acting on it divided by its mass. Therefore, the acceleration of the chain is given by:
a = (Fg - Fn)/m = (mg - mg)/m = 0 m/s^2
Since the acceleration of the chain is zero, the speed of the chain does not change as it drops.

0.6 cm/s at an angle of 40◦ with the long edge.
How long will it take her to get across?
Answer in units of s.
it take the ant 68.9 seconds to get across the other edge of a long strip.
How do we calculate for velocity?If the ant is moving at a constant speed, the velocity vector will have the same magnitude at any point, and can be decomposed in two vectors, along directions perpendicular each other.
So then, if we choose these directions coincident with the long edge of the paper, and the other perpendicular to it, the components of the velocity vector, along these axes, can be calculated as the projections of this vector along these axes.
We only are interested in the component of the velocity across the paper, that can be calculated as follows:
vₓ = v* sin θ, where v is the magnitude of the velocity, and θ the angle that forms v with the long edge.
We know that v= 0.6 cm/s, and θ = 40º, so we can find vₓ as follows:
vₓ = 0.6 cm/s x sin 40 º
Vx = 0.6 cm/s x 0.7451 = 0.447 cm/s

In this figure, why is the kinetic energy gained by the falling ball equal to the change of potential energy? (Assuming no loss of energy due to friction.)
Kinetic energy gained by the falling ball is equal to the change of potential energy is because mechanical energy remains conserved ,it only converts from one form to another form.
The mechanical energy stays rationed when just inner powers follow up on the body and no outside powers are in real life. It implies that motor and potential might continue to change all through the excursion. Be that as it may, their total is steady at each point.
The forces are moderate, i.e., they don't rely upon the way of the moving article and are just subject to the beginning and last position. For instance, the gravitational power is moderate in nature, though the opposition presented via air is non-moderate in nature as it relies upon the way.
From the diagram,we can see that object has potential energy =mgh because of height h.When it was dropped from height h potential energy starts decreasing and kinetic energy starts increasing because of velocity attained by the body.Since mechanical energy is conserved,therefore kinetic and potential energy is equal.

a stone is released from rest at height h at the left side of a loop the loop. what is the minimum height hf ro which the stone will not fall of the track at the top of the loop
At height h, on the left side of a loop, a stone is let free from its resting position. h = v^2/(2 x g) + r must the stone be at in order to stay on the track at the top of the loop.
For a stone to not fall off the track at the top of a loop, it must be traveling fast enough to follow the track's curvature. This means that the stone must have a certain minimum speed at the top of the loop in order to complete it from resting position. The minimum speed required for the stone to complete the loop can be calculated using the equation v = sqrt(gr), where v is the minimum speed, g is the acceleration due to gravity, and r is the radius of the loop. Therefore, the minimum height h for which the stone will not fall off the track at the top of the loop can be calculated using the equation h = v^2/(2*g) + r, where h is the minimum height, v is the minimum speed, g is the acceleration due to gravity, and r is the radius of the loop.

What is acceleration?
In mechanics, acceleration is the rate of change of an object's velocity with respect to time. Acceleration is a vector quantity (as long as it has magnitude and direction). The direction of an object's acceleration is given by the direction of the net force acting on that object.
For example, if a vehicle starts from rest (zero velocity in the inertial frame) and moves in a straight line while increasing speed, the vehicle accelerates in the direction of travel. When the vehicle turns, it experiences acceleration in a new direction and changes its motion vector. Acceleration in the vehicle's current direction of travel is called linear (or tangential, in the case of circular motion) acceleration, and the passenger perceives that response as pushing back into the seat.

A certain type of glass is used in making flat-panel computer monitors. For light with a wavelength in air of 656.3 nm, the refractive index of the glass is nA = 1.5160. For light with a wavelength in air of 435.8 nm, nB = 1.5290. Determine the difference, lA - lB, in their wavelengths inside the glass.
The answer is 147.9 nm. Can you please show the work? Thanks
nB = 1.5290 for light having a 435.8 nm air wavelength. The difference, lA - lB, in their wavelengths inside the glass is 221.4nm.
The refractive index of a medium is defined as the speed of light in a vacuum (c) divided by the speed of light in the medium (v). This can be expressed mathematically as:
= n
= c / v
The wavelength of light in a medium is related to its frequency (f) and its speed in the medium (v) according to the following equation:
= lambda
= v / f
where lambda is the wavelength of the light in the medium.
We can use these equations to find the difference in the wavelengths of the two types of light inside the glass. Letting lA and lB represent the wavelengths of the light with wavelengths 656.3 nm and 435.8 nm inside the glass, respectively, we can set up the following equation:
for nA
= nA
= c / v
= c / (f x lA)
for nB
= nB
= c / v
= c / (f x lB)
Dividing the eq. we know:
=> nA / nB = (f x lB) / (f x lA)
= lB / lA
Inserting the known values for nA, nB, and lA, we get:
=> 1.5160 / 1.5290 = lB / 656.3 nm
Solving for lB, we find that lB = 434.9 nm.
The difference in the wavelengths inside the glass is then:
=> lA - lB = 656.3 nm - 434.9 nm
= 221.4 nm
Therefore, the difference in the wavelengths of the two types of light inside the glass is 221.4 nm.

This argument is valid because the bar is a homogeneous linear conductor, and the magnetic field around it must be constant.
What is magnetic field?A magnetic field is a region of space in which a magnetic force is exerted on any magnet, electric current, or magnetic material. It is created by an electric current, such as the electric current in a wire. It is also created by the motion of electric charges, such as those found in an electromagnet. The strength of the magnetic field increases as the electric current increases. The direction of the magnetic field is determined by the direction of the electric current.
The field at any point along the bar is proportional to the current passing through it, which remains constant for a homogeneous conductor. Therefore, the field at any point along the bar must be the same as at the midpoint, just with a larger magnitude. This implies that the average effective magnetic field along the bar is five times larger than the field at the midpoint.

The Mars rover, Spirit, has a mass of 836 kg.
Calculate its weight on Earth.
Answer:
The weight of an object is a measure of the force of gravity on the object. It is calculated by multiplying the mass of the object by the acceleration due to gravity. On Earth, the acceleration due to gravity is approximately 9.8 meters per second squared (m/s^2).
Therefore, to calculate the weight of the Mars rover Spirit on Earth, we can use the formula:
weight = mass * acceleration due to gravity
In this case, the mass of the Mars rover is 836 kg, and the acceleration due to gravity on Earth is 9.8 m/s^2. Plugging these values into the formula, we get:
weight = 836 kg * 9.8 m/s^2
This simplifies to:
weight = 8194.8 kg*m/s^2
The weight of the Mars rover Spirit on Earth is approximately 8195 kg*m/s^2.

ISurprised? Well, note the following example: For all N, the summation over the binomial coefficients N!/Ir! (N-r!)l gives CNG, 2 r-0 therefore nCNIn2. Now, the largest term in this sum corresponds to r N/2; so, for large N, the logarithm of the largest term is very nearly equal to In(N!)-2In((N/2)!) N, N which agrees with (a).J
Because one mole of H X 2 is typically lighter than N e, it stands to reason that it would have a higher entropy than N e. Ne, on the other hand, is thought to have a higher entropy due to its lower molar mass.
A chemical equation can be examined for changes in physical states and the number of moles of product and reactant particles to predict relative changes in entropy using the same factors on a macroscopic level.
The species with the greater molar mass between two monoatomic ones will have a greater standard entropy. The more mobile of two allotropic forms of an element will have a higher standard entropy value. The entropies of these substances are not zero, despite the fact that their conventional internal energies and enthalpies would be. The "energies of formation" of elements in their normal states are typically set to zero because there is no absolute scale of energy.
Entropy, on the other hand, gauges the distribution of energy among the numerous quantum states that can accept it; they exist even in pure substances.
Evidently, entropies often rise with molecule weight. This is, of course, a direct reflection of the fact that translational quantum states are more densely packed in heavier molecules, making them more occupiable, for the noble gases.

w = angular velocity of earth = 7.29×10^-5
R = radius of earth = 6371000metre
Now, the tension
mg' = mg - mw^2 R
= 415 − 42.34×6371000×7.29×10^-5×7.29×10^-5
= T'= 415-(42.34×6371000×7.29(10^(-5)) ×7.29×(10^(-5)))
T' =413.56 N
