Answer:
Please find the answer in the explanation
Explanation:
Given that a light bulb will glow when electrons flow through it. As the electron flow increases, the brightness increases as well. A student hooks up two circuits containing three light bulbs in each circuit. In one circuit the lights are connected in series and in the other circuit the lights are hooked up in parallel.
If you could only see the lights in the circuit and the wires were covered up, how could you tell the type of circuit?
The type of the circuit can be determined if you loose or unscrew one light bulb, all other bulbs will be switched of if connected in series. But if the others remain on it is a parallel circuit.
For the student box thing I believe it was the grass or carpet I hope this helps a little
Answer:
Due to its larger size
Explanation:
This is due to those planets being much larger than Earth. The larger a planet is, the more gravity that planet has, since gravity is mainly calculated based on the mass and radius of the planet. Also since the pressure deep inside of the planet depends mainly on the gravity of that planet on the surface, this is calculated as the square of the planet's surface gravity. Ultimately, the bigger the planet is the higher the pressure deep inside the planet will be.
Answer:
The 60 kg skater is traveling at 2.63 m/s in the opposite direction from the 45 kg skater.
Explanation:
The velocity of the 60 kg skater can be found by conservation of linear momentum:
(1)
Where:
: is the mass of the first skater = 45 kg
: is the mass of the second skater = 60 kg
: is the initial speed of the first skater = 0 (he is standing still)
: is the initial speed of the second skater = 0 (he is standing still)
: is the final speed of the first skater = 3.5 m/s
: is the final speed of the second skater =?
By replacing the above values into equation (1) and solving for we have:
The minus sign is because the 60 kg skater is moving in the opposite direction from the other skater.
Therefore, the 60 kg skater is traveling at 2.63 m/s in the opposite direction from the 45 kg skater.
I hope it helps you!
