Weight = m (mass) * g (acceleration due to gravity)
g = 9.80 m/s^2
m = 2.5 kg = 2,500 g
Weight = 2,500 g * 9.80 m/s^2
Weight = 24,500 N
The answer for “A 9.0-volt battery delivers a 0.50-A current to a bulb connected across its terminals. delivered What power is to the bulb? (A) 0.056 W (B) 4.5 W (C) 18 W (D) 41 W” would be B. Answer is B!!!
v^2 = v0^2 +2ad
v^2 = 22^2 + 2*3.78*45 = 824.2
v= √824.2 = 28.7 m/s
