The subject would be "Planet of the Apes" :)
Answer:
This indicates the project should not be undertaken.
Explanation:
As we can see from the cost estimation, that the profit is very less than that of the cost. And before evaluating any project we first check it benefit cost ratio. Which is an important factor to judge or to check whether the project is profitable or not. Even though it might help the public but on the other hand that loss will be unbearable. That money could be used for that public on certain other ways. Or can be used for the maintenance of the previously available rail lines
Answer:
5.74
Three significant figures
Explanation:
Distance =35.896m
Time =6.25
Speed = distance / time
= 35.896/6.25
=5.74
Answer:
For object A
m = 5 kg , v= -11 j
For B object
m = 6 kg , v= 5 i +8.7 j
For object C
m = 10 kg , v= -10 i
We know that
Linear momentum P= m v kg.m/s
a) A and C
Momentum in y direction
Py=- 5 x 11 j= - 55 j kg.m/s
Momentum in x direction
Px=- 10 x 10 j= - 100 i kg.m/s
b) B and C
Momentum in y direction
Py=6 x 8.7 j= 52.2 j kg.m/s
Momentum in x direction
Px=( 6 x 5 - 10 x 10 ) i = - 70 i kg.m/s
c) A ,B and C
By using data of a and b
Momentum in y direction
Py= 6 x 8.7 - 5 x 11 j= -2.8 j kg.m/s
Momentum in x direction
Px= 6 x 5 -10 x 10 i = -70 i kg.m/s
