Answer:
b. 40V , 40V
Explanation:
Connections are as per the figure.
As total current through source is 4A , current through each lamp is 1A.
As total resistance of the circuit is 10Ω ,resistance of each bulb is 40Ω because in case of a parallel circuit in which identical objects are connected , 
where R is the resistance of each bulb and n is the number of bulbs.
As per Ohm's law , voltage of the source =IR = 4×10 =40V.
We can see from the figure that if the voltage across the source is 40V , the voltage across each bulb is also 40V.
Answer:
it points towards positive charges
Potential equals kenecric at the bottom so potential would also increas
Answer:
150 N= 15 or 150 N= 1.1
Explanation:
What I did was subtract 165kg and 150 N and I divided it too but I got 1.1 so yuhh
Answer:
Explanation:
If a rocket (firework) is launched
with an initial velocity of 39.2 meters per second at a height of 1.6 meters above
the ground, the equation h = -4.9t2
+ 39.2t + 1.6 represents the rocket’s height h in
meters after t seconds. The rocket will explode at approximately the highest point.
Fire official require the fireworks to explode at a height greater than 76 feet in
order for debris to land in Lake Michigan and not on the festival sight. The event
planners assured the fire officials that the fireworks would reach a height greater
than 76 feet
