Answer:

Red has the longest wavelength among all the visible colors of light.

Explanation:

Visible light is the only electromagnetic radiations which can be seen by human eye. When white visible light passes through a prism it breaks down into 7 distinctive colors of rainbow.

These are red, orange, yellow, green blue, indigo and violet.

Red has the longest wavelength of around 700 nano meters with violet has the shortest wavelength of 380 nano meters.

A 66-foot-tall woman walks at 55 ft/s toward a street light that is 2424 ft above the ground. What is the rate of change of th

I am Lyosha [343]

Answer:

a. $\frac{dx}{dt}=20ft/s$

b. $\frac{d(x+L)}{dt}==25ft/s$

Explanation:

Using the triangle theorem both triangle the woman makes between the light so the rate of change of length can use geometry first

$tan(\beta)=\frac{24ft}{L+x}=\frac{6ft}{x}$

Solve to find the rate relation

$x=\frac{24}{6}*L$

$x=4*L$

Now the rate of the change rate

$\frac{dx}{dt}=4*\frac{dL}{dt}$

$\frac{dx}{dt}=4*5ft/s=20ft/s$

Finally the rate of her shadow moving

$\frac{d(x+L)}{dt}=\frac{dx}{dt}+\frac{dL}{dt}$

$\frac{d(x+L)}{dt}=20ft/s+5ft/s=25ft/s$

Which scientist described an atom made of a solid positively charged substance with electrons dispersed throughout it?.

swat32

The scientist that described an atom made a solid positively charged substance with electrons dispersed throughout it was: Ernest Rutherford

In 1911 Ernest Rutherford proposed his atomic model in which he considered the atom as a positively, densely charged center called a nucleus in which the electrons circulate around the core with a negative charge.

The atom is the smallest part of the composition of matter, it is indivisible and is composed of a nucleus that has protons and neutrons, and around the nucleus there are the electrons.
