Answer:
The answer would be A. - the temperature remains constant
Explanation:
An isothermal process is a change of a system, in which the temperature remains constant: ΔT = 0
Answer:
Violet Light
Explanation:
On one end of the spectrum is red light, with the longest wavelength. Blue or violet light has the shortest wavelength. White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow.
Answer:
A) E = 3.70*10^{4} N/C
B) E = 2.281*10^3 N/C
Explanation:
given data:
charge density
length of wire = 9.50 cm
a) at x = 4.5 m above midpoint, electric field is calculated as
x = 4.5 cm
midpoint a = 4.5 cm = 0.0475 m
E = 3.70*10^{4} N/C
B) when wire is in circle form
= 1.235*10^{-8} C
Radius of circle
r = 1.511*10^{-2} m
E = 2.281*10^3 N/C
I just figured this out now.
First you would use the formula
Ephoton= hc/λ and substitute in the value's of plank's constant, the speed of light in a vaccum and the wavelength which will give you the energy in joules. Then you go to the reference table and solve for the energy used between the different levels for Mercury making sure to convert electron volts to jules. In the end the correct answer should be energy level D.
The law of conservation of energy states that energy is neither created nor destroyed, but can be converted from one form to another.
When the book was at the shelf, its kinetic energy was zero and its potential energy was maximum. As it fell, its potential energy stated converting to kinetic energy. Before the book directly hits the ground, its kinetic energy is maximum and its potential energy is zero.
Based on the above explanation, at the moment the book landed on the floor, ALL the potential energy was converted to kinetic energy, so the kinetic energy = 67 Joules.
