Answer:
Explanation:
Given
Velocity of traffic 
Maximum value of Centripetal force is one-tenth of weight
such that 
to make a safe turn centripetal force with radius of curvature r is given by






Answer:
Since there is no external force, there is no change (movement) in the center of mass. Internally, the center of mass might change position, but the external result is still zero net velocity.
The net recoil velocity must be zero.
They both-
1) are vector fields
2) they both transmit forces between objects
I hope this helps :))
By Kirchoff's law in left side loop

similarly kirchoff's law in right side loop

also by junction law we know that

now by plug in all values we have




So by solving above equations we have



Explanation:
An IC engines means an Internal Combustion engine. Here, the combustion takes place in side a chamber or a cylinder internally, hence it is known as internal combustion engine.
Combustion is the process where oxygen reacts with the fuel and it burns to produce a large amount of force and heat. In each revolution of the crank, the engine creates a power stroke when the piston goes from the bottom dead center to the top dead center.
During each power stroke, the energy released forces the piston down and the crankshaft is rotated.
