Complete question: A wagon is pulled at a speed of 0.40 m/s by a horse exerting 1800 Newtons of horizontal Force. how much work was done by the horse per second.
What is an atomic nucleus
The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment.
An isotropic point source emits light at wavelength 500 nm, at the rate of 185 W. A light detector is positioned 380 m from the source. What is the maximum rate ∂B/∂t at which the magnetic component of the light changes with time at the detector's location?
An isotropic point source emits light at a wavelength = 500 nm
Power = 185 W
Radius = 380 m
Let's first calculate the The intensity of the wave , which is =
The amplitude of the magnetic field is calculated afterwards by using poynting vector
The magnetic field wave equation can now be expressed as;
Taking the differentiation
The maximum value ;
The maximum rate at which the magnetic component of the light changes with time at the detector's location is approximately Tesla per second (T/s).
To find the maximum rate at which the magnetic component of the light changes with time at the detector's location, you can use the formula for the rate of change of magnetic field due to an electromagnetic wave. The formula is given by:
is the rate of change of the magnetic field.
λ is the wavelength of the light.
E is the electric field strength.
c is the speed of light in a vacuum, approximately
You have the wavelength (λ) as 500 nm, which is 500 x 10^-9 meters, and the electric field strength (E) can be calculated using the power (P) and the distance (r) from the source. The power emitted by the source is 185 W, and the distance from the source to the detector is 380 m.
First, calculate the electric field strength (E):
Now, you can calculate the rate of change of the magnetic field:
So, the maximum rate at which the magnetic component of the light changes with time at the detector's location is approximatelyTesla per second (T/s).

Which of the following is a description of the Remote Associates Test (RAT)?
The description is outlined throughout the clarification section following, and according to the given word.
Throughout the 1960s, Sarnoff Mednick created the RAT as a tool used for testing imaginative convergent thought. Through each RAT test query lists a set of terms, which demands that we have a single additional term that will tie any of the others around.
Those other words may also be related in something like a variety of ways, such as through creating a compound word or perhaps a semantic connexon.
