When an electric current is flowing through a wire, there is a magnetic <em>field</em> produced. The lines of magnetic force are circles around the wire.
Answer:
Pressure Increases
Explanation:
When the temperature of a gas is increased inside a container then the pressure of the gas inside the container increases.
This can be deduced by the Ideal Gas law equation:
where:
P = pressure of the gas
V = volume of the gas
n = no. of moles of gas
R = universal gas constant
temperature of the gas
So,
hence the pressure of the gas will increase while the temperature is increased at a constant volume
Answer:
The metal coil of the slinky
Explanation:
The wave travels on the actual slinky which we see deforming as the wave goes through.
An atom would be your answer, so B!
Answer:
Final velocity = 7.677 m/s
KE before crash = 202300 J
KE after crash = 182,702.62 J
Explanation:
We are given;
m1 = 1400 kg
m2 = 4700 kg
u1 = 17 m/s
u2 = 0 m/s
Using formula for inelastic collision, we have;
m1•u1 + m2•u2 = (m1 + m2)v
Where v is final velocity after collision.
Plugging in the relevant values;
(1400 × 17) + (4700 × 0) = (1400 + 1700)v
23800 = 3100v
v = 23800/3100
v = 7.677 m/s
Kinetic energy before crash = ½ × 1400 × 17² = 202300 J
Kinetic energy after crash = ½(1400 + 1700) × 7.677² = 182,702.62 J
