Answer: 28
Explanation:
Given
Circuit breaker current is
Power of the light bulb is
Voltage of the DC-circuit is
If the resistance are connected in parallel, they must have same voltage i.e. 120 V
So, Resistance is given by
For the 20 A current and 120 V battery, net resistance is
Suppose there are n resistance in the circuit connected in parallel.
Thus, there can maximum of 28 bulbs.
Im not sure but i think its 4ft
hope this helps
At 100 km/hr, the car's kinetic energy is
KE = (1/2) (mass) (speed)²
KE = (1/2) (1575 kg) ( [100 km/hr] x [1000 m/km] x [1 hr/3600 sec] )²
KE = (787.5 kg) (27.78 m/s)²
KE = 607,639 Joules
In order to deliver this energy in 2.9 seconds, the engine must supply
(607,639 J / 2.9 sec) = 209,531 watts
<em>Power = 281 HP</em>
Answer:
