difference between universal law of gravitation and acceleration due to gravity
Explanation:
The acceleration on an object due to the gravity of any massive body is represented by g (small g). The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G(capital g). The relation between G and g is not proportional. That means they are independent entities.
G and g
In physics, G and g can be related mathematically as –
\(g=\frac{GM}{R^{2}}\)
Where,
1=g is the acceleration due to the gravity of any massive body measured in m/s2.
2=G is the universal gravitational constant measured in Nm2/kg2.
3=R is the radius of the massive body measured in km.
4=M is the mass of the massive body measured in Kg.

in their most basic sense, waves are . they are generally classified by the disturbing force that causes the wave and the restoring force that returns the water to normal once it has passed. for example, the disturbing force for wind waves is usually and the restoring force is .
Answer:
The restoring force is Gravity.
Explanation:
In their most basic sense, waves are disturbances that travel through a medium, usually without the permanent displacement of the particles of the medium.
They are generally classified by the disturbing force that causes the wave and the restoring force that returns the water to normal once it has passed.
For example, the disturbing force for wind waves is usually wind and the restoring force is gravity.
Wind provides energy to the water, creating ripples and waves that travel across the surface of the water.
Gravity then acts to restore the surface of the water to its original state, pulling the water back down into the trough of the wave.
As the wave moves through the water, the water itself does not travel with the wave but instead moves in a circular motion, with the circular motion decreasing in size as it moves away from the wave.
This motion of the water is known as an orbital motion, with water particles moving in a circular motion but not traveling with the wave itself.

When you put a 9. 0 V battery across a bulb, 0. 1 A of current
flows through the bulb. Calculate the resistance of the bulb
When a 9.0 V battery is connected to a bulb and 0.1 A of current flows through it, the resistance of the bulb is 90 ohms.
When a 9.0 V battery is connected to a bulb and 0.1 A of current flows through the bulb, we can calculate the resistance of the bulb using Ohm's Law. Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance.
To find the resistance, we can rearrange Ohm's Law equation (V = IR) to solve for R, where V is the voltage, I is the current, and R is the resistance.
First, let's plug in the given values:
V = 9.0 V (voltage)
I = 0.1 A (current)
Now, we can rearrange the equation to solve for R:
R = V / I
Substituting the given values:
R = 9.0 V / 0.1 A
Dividing 9.0 V by 0.1 A, we get:
R = 90 ohms
Therefore, the resistance of the bulb is 90 ohms.
In summary, when a 9.0 V battery is connected to a bulb and 0.1 A of current flows through it, the resistance of the bulb is 90 ohms.

The conductance of a wire varies directly as the square of the wire's diameter and inversely as its
length. Fifty meters of wire with diameter 2 mm has conductance 0.12 mho (unit of conductance).
If a wire of the same material has length 75 m and diameter 2.5 mm, what is its conductance?
Since it varies directly with the square of the wire's diameter and inversely with wire length, the conductance of a wire is 0.15 mho.
Does a wire's electrical resistance change inversely with its square of diameter and directly with its length?A wire's electrical resistance varies inversely as the square of its diameter and directly as its length. A wire with a diameter of 1/4 inch and a length of 200 inches has a 20 ohm resistance.
Let L be the wire's length, d its diameter, and C its conductance be the parameters.
Based on the facts provided, we can:
C ∝ d² (conductance varies directly as the square of the diameter)
C ∝ 1/L (conductance varies inversely as the length)
Combining these two proportionalities, we get: C ∝ d²/L
This connection can be used to find a solution to the issue. Using the numbers for the 50 m wire, we can first calculate the proportionality constant as follows:
C = k(d²/L)
0.12 = k(2²/50)
k = 0.12*50/4 = 1.5
So, using this value of k, we can determine the conductance of a 75 m wire with a 2.5 mm diameter:
C = k(d²/L)
C = 1.5*(2.5²/75)
C = 0.15 mho

Assume you are flying in an airplane at 10 km where the outside temperature is 230 K, the pressure is 300 mb and O3 is present at 150 ppbv. Assuming no chemical transformations, what would the ozone mixing ratio be in units of ppbv inside the airplane after air is brought into the plane from outside assuming the cabin air temperature is 298 K and the cabin pressure is 600 mbar?
The ozone mixing ratio inside the airplane would be 82.4 ppbv.
The ozone mixing ratio would be 82.4 ppbv inside the airplane after air is brought into the plane from outside, assuming the cabin air temperature is 298 K and the cabin pressure is 600 mbar. Here's how we can arrive at that answer:First, we need to use the ideal gas law to calculate the number density of the air outside of the plane:n/V = P/RTwhere:n/V is the number density of the air in units of molecules/cm^3P is the pressure in units of dynes/cm^2R is the gas constant in units of erg/(mole*K)T is the temperature in units of KConverting the given values to the proper units, we get:n/V = (30000 Pa) / [(8.31 J/(mole*K)) * (230 K)] * (1 Pa / 10 dynes/cm^2) * (1 cm / 10 mm)^3 * (6.022e23 molecules / mole) = 2.34e19 molecules/cm^3Next,
we can calculate the number density of ozone in the air outside of the plane by multiplying the ozone mixing ratio by the total number density of air:O3 mixing ratio = 150 ppbv = 150 nmol/mol = 150e-9 mol/molO3 number density = (150e-9) * (2.34e19) = 3.51e12 molecules/cm^3Now, we can use the conservation of mass to calculate the ozone mixing ratio inside the plane after air is brought in from outside. Since no chemical transformations are occurring, the total number of ozone molecules inside the plane must be equal to the number of ozone molecules brought in from outside.
We can write this as:O3 number density inside * volume inside = O3 number density outside * volume outsideSince we are interested in the ozone mixing ratio inside the plane, we can rewrite this as:O3 mixing ratio inside = O3 number density outside * volume outside / (n/V inside * V inside)First, we need to calculate the volume outside. We know that the plane is flying at an altitude of 10 km, which corresponds to a pressure of 265 mb according to the U.S. Standard Atmosphere.
Using the ideal gas law again, we can calculate the number density of the air at this altitude:n/V = (26500 Pa) / [(8.31 J/(mole*K)) * (230 K)] * (1 Pa / 10 dynes/cm^2) * (1 cm / 10 mm)^3 * (6.022e23 molecules / mole) = 2.06e19 molecules/cm^3The volume outside can then be calculated using the ideal gas law and the given conditions for pressure and temperature:V outside = nRT / P = (2.06e19) * (8.31e7) * (230) / (30000) = 4.84e11 cm^3Now, we can calculate the ozone mixing ratio inside the plane:V inside = V outside * P inside / P outside = (4.84e11) * (600) / (30000) = 9.68e9 cm^3n/V inside = (60000 Pa) / [(8.31 J/(mole*K)) * (298 K)] * (1 Pa / 10 dynes/cm^2) * (1 cm / 10 mm)^3 * (6.022e23 molecules / mole) = 4.09e19 molecules/cm^3O3 mixing ratio inside = (3.51e12) * (4.84e11) / (4.09e19 * 9.68e9) = 82.4 ppbv Therefore, the ozone mixing ratio inside the airplane would be 82.4 ppbv.

at x=5m the force is known to point in the -x direction and have a magnitude of 25n. determine the potential energy
To determine the potential energy at a given point, we need to know the conservative force acting on an object and integrate it over the displacement.
In this case, we know that the force at x = 5 m is directed in the -x direction and has a magnitude of 25 N. Let's assume that the potential energy is zero at some reference point, typically chosen as the point where the force is zero.The potential energy associated with a conservative force can be calculated by integrating the negative of the force with respect to displacement:
Potential energy = -∫(Force)dx
Since the force is constant and directed in the -x direction, the integration simplifies to:
Potential energy = -Force * ∫dx
Evaluating the integral, we have:
Potential energy = -Force * (x - x₀)
Substituting the given values, we have:
Potential energy = -25 N * (5 m - x₀)
Since the potential energy is determined up to an additive constant, we can choose any reference point x₀. If we choose x₀ = 0, the equation simplifies to:
Potential energy = -25 N * (5 m - 0)
Potential energy = -125 J
Therefore, the potential energy at x = 5 m, with a force of magnitude 25 N directed in the -x direction, is -125 J.
