B long board because of the length
Initial velocity = 
acceleration in the downward direction = -9.8 
Final velocity at the highest point = 0
Maximum height reached = 0.410 m
Now, Using third equation of motion:
Speed with which the flea jumps = 
Tu no mete cabra saramambiche
Answer:
The correct option is;
Technician A only
Explanation:
Leaks in the cooling system parts such as the radiator cap can be tested with a pressure operated hand pump by attaching the pump cap to the pump with an adaptor and apply pressure enough for there to be a release of pressure at the cap.
The pressure added to the system should be maintained for up to two minutes. If the pressure drops quicker, then there is likely to be leaks in the system
The freezing and boiling point of the coolant is measured with an antifreeze tester which carries the appropriate apparatus to measure the coolants freezing and boiling points.
Answer:
D 500 N
Explanation:
As the velocity is constant the scale reads the same whether at rest, or at a fixed velocity. The only thing that would make the scale read differently would be a vertical acceleration.
