Neon is element #10, so every neon atom has 10 protons in the nucleus.

If it also has 9 neutrons in there, then its mass number is (10 + 9) = 19 .

What does it mean if electric field lines are close together versus farther apart ?

hoa [83]

Answer:

As a result, if the field lines are close together (that is, the field line density is greater), this indicates that the magnitude of the field is large at that point. If the field lines are far apart at the cross-section, this indicates the magnitude of the field is small. (Figure) shows the idea.

To determine the height of a flagpole, Abby throws a ball straight up and times it. She sees that the ball goes by the top of th

Kryger [21]

Answer:

$H = 10.05 m$

Explanation:

If the stone will reach the top position of flag pole at t = 0.5 s and t = 4.1 s

so here the total time of the motion above the top point of pole is given as

$\Delta t = 4.1 - 0.5 = 3.6 s$

now we have

$\Delta t = \frac{2v}{g}$

$3.6 = \frac{2v}{9.8}$

$v = 17.64 m/s$

so this is the speed at the top of flag pole

now we have

$v_f - v_i = at$

$17.64 - v_i = (-9.8)(0.5)$

$v_i = 22.5 m/s$

now the height of flag pole is given as

$H = \frac{v_f + v_i}{2}t$

$H = \frac{22.5 + 17.64}{2} (0.5)$

$H = 10.05 m$

In two or more complete sentences, describe the purpose and outcome of the Miller Urey experiment.

Rama09 [41]

Miller Urey experiment's purpose was to test the chemical origin of life under the conditions supposed to be present on the early Earth.
The scientists Miller and Urey heated a mixture of water, ammonia, methane and hydrogen in a sterile flask until it evaporated water to produce water vapour. Electric sparks were passed through the mixture of water vapour and gases, simulating lightning. The experiment was done during one week. After a week, the contents were analysed and Miller and Uray proved that several organic compounds could be formed spontaneously by simulating the conditions of Earth's early atmosphere.

The following acceleration vs time plots show

fenix001 [56]

The data set that is most likely from the car equipped with ABS is :

The First ( upper ) plot

Although the plots related to your question is missing attached below is the missing data.

The First plot ( acceleration vs time ) plot is the data that represents the application of brakes in a car fitted with ABS ( antilock braking system ) because of the absence of skidding effect between 6.5 and 9 seconds in the graph.

The skidding effect is present in the second plot around the same time because the car is not fitted with ABS

Hence we can conclude that the graph that shows the car fitted with ABS is the first plot .
