The correct choice is D, and it's convection, not conversion.
Answer:
1.75 s
11.4 m
Explanation:
In the y direction:
Given:
Δy = -15.0 m
v₀ = 0 m/s
a = -9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
-15.0 m = (0 m/s) t + ½ (-9.8 m/s²) t²
t = 1.75 s
In the x direction:
Given:
t = 1.75 s
v₀ = 6.50 m/s
a = 0 m/s²
Find: Δx
Δx = v₀ t + ½ at²
Δx = (6.50 m/s) (1.75 s) + ½ (0 m/s²) (1.75 s)²
Δx = 11.4 m
The electromagnetic radiation produced when a charged particle moves spirally in a magnetic field is called <span>synchrotron radiation. This phenomenon occurs due to the fact the particle is accelerated radially (due to the presence of the magnetic field), and every charged particle when it is accelerated emits electromagnetic radiation.</span>
Answer:
Explanation:
As we know that position of first minimum on the either side of central maximum is given as
so the width of the central maximum is given as
so we have
so we have
Answer: "One object speeds up before it slows to a stop
"
(the top one)
Explanation:
Ok, first a little recall on how to read this type of graph.
If the points are far apart, the object is moving fast.
If the points are close together, the object is moving slow.
If the distance between the points changes then the velocity of the object changes, which means that the object is accelerated.
If we have a lot of points clustered in one location, then the object is not moving.
We can see:
The top object starts slow, then it increments the speed, then it slows down again, and then it comes to stop.
The bottom object starts fast, and it slows down.
then:
"One object speeds up before it slows to a stop
"
This describes the motion of the top object, this is the only correct option that describes one of the graphs.
