A Cessna Citation II jet (call number 90-RC) has a lift-off velocity of 260 km/hr. The runway that 90-RC takes off from is 1200 m long. (a) What is the minimum acceleration that the jet has to have in order to take off before it reaches the end of the runway? (b) How long does it take for 90-RC to take off? (c) 20 s into the takeoff, a fault occurs in one of the engines. From this point on, what acceleration does the jet need in order to stop before it reaches the end of the runway?

find the sum of the two horizontal vectors and the sum of the two vertical vectors

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m

if i am correct, your answer choices are:

a. the temperature remains constant

b. the temperature increases at a constant rate

c. heat flows at a constant rate into the system

d. heat flows at a constant rate out of the system

e. no heat flows into or out of the system

if so, then the answer is e. no heat flows into or out of the system.
