Answer: True
Explanation:
Distance is a scalar, which means it has no direction. It is the sum of the entire path traveled.
Displacement is a vector, which means it does have direction. It is the shortest path from the start to the end. It is defined as .
The answer is Gamma Rays the have the highest frequency but lowest wave
True, according to the Kinetic Molecular Theory.
B. The kinetic energy will decrease.
To determine the number of photons emitted per second, we need data on the total power of the system and the total energy of the photons. We determine the power by multiplying the total area to the intensity of the sunlight given. We do as follows:
Power = 0.50 kW / m^2 ( π (0.001^2)) = 1.57x10^-6 kW = 1.57x10^-3 W
The energy of the visible light can be calculated from the expression:
Energy = hc / wavelength
where h is the planck's constant and c is the speed of light
Energy = (6.63 x 10^-34) (3 x 10^8) / 550 x 10^-9
Energy = 3.62 x 10^-19 J
Number of photons per second = 1.57x10^-3 J/s / 3.62 x 10^-19 J
Number of photons per second = 4.34x10^15
