May be

It is depend up on your level of thinkin
But in graduation may be not second option will consider
....
Work = (force) x (distance)
40,000 J = (20 N) x (distance)
Distance = (40,000 J) / (20 N)
= 2,000 meters
= 2 kilometers.
(20 N is not a huge force when it's being used to move a car.
It's only about 4.5 pounds.)
Water pollution can affect the economy because with no clean water, people will be forced to buy water bottles impacting their disposable income. In the search for clean water, potential future conflicts may occur because water is a fundamental need to human survival. :)

B. Technician B only
Explanation:
Technician A says that valve overlap is the number of crankshaft degrees that both valves are closed. Technician B says that valve overlap is the number of degrees that both valves are open. Who is right? A. Technician A only B. Technician B only C. Both technicians A and B D. Neither technician A nor B
Valve overlap is when both the intake and exhaust valves are open. This occurs towards the end of the exhaust stroke, the intake valves are opened just before all the exhaust gases are released, providing more time for the intake air to enter the engine. Valve overlap must be shorter for a petrol/gasoline engine because the engine is drawing in fuel as well as air through the intake. ...it is not so for a sport car
the inlet valve and exhaust valve are located at the head of the engine. fuel enters the engine through the intake valve.
