The Maglev is a system of train transportation that uses two sets of magnets
working repel one another when matching poles face each other. Here, both magnetic attraction and repulsion are used to move the train car along the guideway.

Answer:
Total time taken = 0.769 hour
Explanation:
using the velocity method
for sheet flow ;
Tt =
Tt = travel time
n = manning CaH
Pl = 25years
L = how length ( ft )
s = slope
For Location ( 1 )
s = 0.045
L = 1000 ft
n = 0.06 ( from manning's coefficient table )
Tt1 = 0.128 hour
For Location ( 2 )
s = 2.5 %
L= 750
n = 0.13
Tt2 = 0.239 hour
For Location ( 3 )
s = 1.5%
L = 500 ft
n = 0.15
Tt3 = 0.237 hour
For Location (4)
s = 0.5 %
L = 250 ft
n = 0.011
Tt4 = 0.165 hour
hence the Total time taken = Tt1 + Tt2 + Tt3 + Tt4
= 0.128 + 0.239 + 0.237 + 0.165 = 0.769 hour
Answer:
(a) lonic bonding
Explanation:
The Strongest chemical bond is the ionic bond ,
Because ionic bond is bound by strong electrostatic interactions ,
The ionic bond forms crystal lattice structure which are bounded by electrostatic interactions but the covalent bond is formed by the van der waal forces .
Hence , ionic bond is stronger than covalent bond .

Answer:
=0.60
Explanation:
Given :Take =1.4 for air
=r ⇒ r=16
As we know that
So
=909.42K
Now find the cut off ration
So efficiency of diesel engine
Now by putting the all values
So =0.60
So the efficiency of diesel engine=0.60
