Answer:
C. (100+4.9)m
Explanation:
u = 100m/s, t = 1 sec, g = 9.8m/s^2
s = ut + 1/2gt^2
s = 100×1 + 1/2×9.8×1^2 = 100+4.9
s = (100+4.9)m
I think it is 100 dB .I holp it is help.
I think it is building and managing of irrigation systems
Planet Mars has gravitational pull "g" which has a value of g = 3.711 m/s²
Given: Mass m = 65 Kg
Formula: Weight = mg
W = (65 Kg)(3.711 m/s²)
W = 241 N
Answer:
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.
