Answer:0.853
Explanation:
Given
Reliability of A is 0.90
Reliability of B is 0.80
Reliability of C is 0.99
B has a backup with reliability of 0.8
i.e. B has a component in parallel to it.
A,B& C is series.
B actual reliability is
Thus 
is given by
Answer:
20 m/s
Explanation:
initial velocity, u= 25m/s
u has two components. one in horizontal and in one vertical.
so,
u sin theta = vertical component.
=> u sin theta = 25× 4/5
= 20 m/s
Its D because i know that smoke does change very easily and its particles that dissolves in air which was infuenced by the gas. hope this helps man ;)
Answer:
This has all the answer (Data sheet, graph, answers to the questions, and the summary) :)
First the plane turns 100 km North, and than 200 km East. Since both the directions are perpendicular to each other, therefore we can apply the Pythagoras theorem to calculate the distance between the destination and the point where plane took off
=100^{2}+200^{2}
D=223.60 km=224 km
Therefore, The destination is 224 km from where the plane took off
