Vector u :
u = 6 i - 3 j
The magnitude of vector u :
| u | =
Answer:
The magnitude of vector u is 3√5.
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.
Hello!
What Deshawn notices is that the volume of the bubbles increase as they get closer to the surface of the water.
This occurs because of the
Boyle's Law. That Law states that when pressure decreases at constant temperature (like in water), the volume of a gas increases (
).
What is happening is that as the bubbles get closer to the surface of the water, the pressure on them decreases, causing their
volume to increase, and that is seen by the increase in the size of the Bubbles that Deshawn noticed.
Have a nice day!
Answer:
Explanation:
Those kind of problems of electric physics is about capacitors, so the normal questions are:
What are the charge on each electrode?
Solve this you can get other information required in the problem or write down the other questions you need
Capacitance
The charge is find by the equation
Football helmets that are made with padding are believed to have reduced head injuries especially when a player accidentally collides with an object. This is because the impact of the collision is decreased due to the padding that serves as a shock absorber.
