Answer:
work done = 48.88 × 
J
Explanation:
given data
mass = 100 kN
velocity = 310 m/s
time = 30 min = 1800 s
drag force = 12 kN
descends = 2200 m
to find out
work done by the shuttle engine
solution
we know that work done here is
work done = accelerating work - drag work - descending work
put here all value
work done = ( mass ×velocity ×time - force ×velocity ×time - mass ×descends ) 10³ J
work done = ( 100 × 310 × 1800 - 12×310 ×1800 - 100 × 2200 ) 10³ J
work done = 48.88 × J
Answer:
A piece of code hidden in spread sheet
Answer:
The composition of an alloy is 0.75%wt
Explanation:
Let alloy is a hypoeutectoid alloy.
So, we can apply lever rule which is shown below.
We know that 
and 
Given that 
, we have to find 
Thus,
Hence
%wt
Answer:
Thread cancellation is the task of terminating a thread before it has completed.
Explanation:
In computers and technology, the concept of thread cancellation explains how a thread can be stopped while it is still in the process of execution.
It can also be done in such a way that it checks at intervals if it can safely cancel itself before it then proceeds with the cancellation.
