If a photon has a wavelength of about 10^-10 meters, it would be certainly in the X rays region and it would have a frequency of 2.99792458x10^18 Hz, that you can easily calculate using the relation that states that the product of the wavelength and the frequency of an electromagnetic wave aka light is always equal to 299,792,458 m/s which is the exact value of the speed of light!
Mass of caboose 1000 kg
mass of caboose plus mass of middle car = 3000 kg
a = 5
F = ma
3000 * 5 = 15.000 N
hope this help
Well, a few main reasons would be that they have confidence in themselves, they have knowledge that is work related, and to me most important, motivation. You need to motivate yourself to do something if you want to acheive a goal right? Same idea.
Can you put this in english plz i dont want to be rude but i cant read this at all
First, we will get the mass of the elevator:
Fw = mass * gravitational acceleration
2 * 10^5 = mass * 9.8
mass = 20.4 * 10^3 kg
Now, the total force acting on the elevator can be written as follows:
Fnet = Tension - Fw
mass * acceleration = Tension - 2*10^5
20.4 * 10^3 * 3 = Tension - 2*10^5
61200 = Tension - 2*10^5
Tension = (61200) + (2*10^5)
Tension = 2.61 * 10^5 newton
