Looking at the same nonmetal group on the periodic table, how does the reactivity of an element in period 2 compare to the react

ivity of an element in period 4? The period 2 element would be more reactive because the attractive force of protons is stronger when there are fewer neutrons interfering. The period 2 element would be more reactive because the attractive force of protons is stronger when electrons are attracted to a closer electron shell. The period 4 element would be more reactive because the attractive force of protons is stronger when there are more neutrons helping. The period 4 element would be more reactive because the attractive force of protons is stronger when electrons are attracted to a farther electron shell.

The reactivity of a nonmetal element in period 2 would be more violent than an element in period 4, as the size of the element and its ability to gain electrons would decrease as you go down the group in the table. Nonmetals want to form negative ions, as their weak valence shell allows them to gain electrons from other elements.

From the information gathered, the answer is '<span>The period 2 element would be more reactive because the attractive force of protons is stronger when electrons are attracted to a closer electron shell'. </span>

Tresset [83]

Answer:

450W

Explanation:

V= I*R

V=3A*50 Ohms

V=150V

P=I*V

P=3A*150V

P=450W

Juan is standing on the street. An ambulance moves toward him and then passes by. What best describes the pitch that Juan hears?
ozzi

Answer: The correct answer is "the pitch drops to a lower pitch once the ambulance passes by Juan".

Explanation:

Doppler effect is the phenomenon in which there is an increase or decrease in the frequency when there is relative motion between the source and listener.

Pitch depends on the frequency. if the frequency increases then pitch increases.

When the source and the listener are moving towards each other then there is increase in the frequency. When the source and the listener are moving away each other then there is decrease in the frequency.

In the given problem, Juan is standing on the street. An ambulance moves toward him and then passes by the pitch drops to a lower pitch once the ambulance passes by Juan.

The maximum height to which the ball attain before falling back down is 1147.96 m

<h3>Data obtained from the question</h3>

The following data were obtained from the question:

  • Initial velocity (u) = 150 m/s
  • Final velocity (v) = 0 m/s (at maximum height)
  • Acceleration due to gravity (g) = 9.8 m/s²
  • Maximum height (h) =?

<h3>How to determine the maximum height </h3>

The maximum height reached by the ball can be obtained as illustrated below:

v² = u² – 2gh (since the ball is going against gravity)

0² = 150² – (2 × 9.8 × h)

0 = 22500 – 19.6h

Collect like terms

0 – 22500 = –19.6h

–22500 = –19.6h

Divide both side by –19.6

h = –22500 / –19.6

h = 1147.96 m

Thus, the maximum height reached by the ball is 1147.96 m

Ne4ueva [31]

Answer:

impossibility

Explanation:

We can assume or conclude that he must have made an error in his experiment. This is because, that kind of speed has been tagged to be impossible by a number of previous experiments. Cosmic rays are high energy protons and atomic nuclei that moves through space at a speed just close to light. They can come from the sun, distant galaxies and even outside if our solar system.
