We just consider the moves of the jumbo jet, not it's causes (we solve it kinematically)
It has a constant acceleration, so then we may use this equation to solve our problem: a = Vf^2 - Vo^2 / 2∆x
Vf (The max velocity that allowed) = 360 Km/h
Vo = 0 (At rest)
∆x = 1.5 Km
then..
a = (360)^2 / (2)(1.5) = 43200 Km/h^2
Convert those numbers to m/sec^2 you will surprised by the results=))
Answer:
Explanation:
Given
height from which ball is dropped 
and it rises to a height of 
A person caught the ball in mid-way i.e. at a height of 
from pavement
time taken to reach the bottom is given by
where y=displacement
u=initial velocity
a=acceleration
t=time
here initial velocity is zero i.e.
Similarly to reach of height 
time taken is 
The ball is caught in mid-way i.e. ball travel a distance of 
time taken is 
total time taken 
total time =3.429 s
Answer:
higher, lower, external work, 100 %, work.
Explanation:
These paragraphs refer to the second law of thermodynamics. There are two statements for the second law of thermodynamics. They are as follows:
KELVIN STATEMENT:
All the heat from a source can never be transferred to the sink without the rejection of some heat.
CLAUSIUS STATEMENT:
Heat can not be transferred from a colder body to a hotter body without the application of som external work.
According to the statements the blanks can be filled as follows:
Heat naturally flows from an object that has a <u>higher</u> temperature to an object that has a <u>Lower</u> temperature. Heat can be made to flow in the reverse direction if <u>external work</u> is done. A machine can never have an efficiency of <u>100 %</u>. This means that heat energy can never be fully converted into <u>work</u> energy.
