( Pennfoster plz help ) Which of the following does not accurately describe the forces that exist with an atom? A. Electrons closer to the nucleus and electrons farther from the nucleus repel due to like charges. B. Electrons positioned farther away from the nucleus are less attracted to the nucleus than are electrons positioned closer to the nucleus. C. Electrons positioned closer to the nucleus have a greater attraction to the protons and are more likely to be discharged from the atom than electrons farther away. D. Electrons in an atom are attracted to the protons within the nucleus due to opposite charges.

Answers

Answer 1

Answer:

I would say C i'm not 100% sure

Answer 2

Answer:

Choice-C is nonsense.

Electrons positioned closer to the nucleus are closer to the protons in the nucleus and more strongly attracted to them. Therefore these electrons are LESS likely to be discharged from the atom than electrons farther away from the nucleus are.

Answer: orbit the earth

Explanation:

In 1962, with three orbits around the Earth, John Glenn is the first American Astronaut to do so.

John Glen was selected in NASA in 1959. He flew Friendship 7 mission on 20th February, 1962. He was the first American to orbit the Earth. He took three rounds about the Earth.

A car accelerates uniformly from 5m/s to 15m/s taking 7.5 seconds. How far did it travel during this periodPls help

Answers

Answer:

Given :-

Initial Velocity (u) = 5 m/s

Final Velocity (v) = 15 m/s

Time (t) = 7.5 seconds

To Find :-

Distance (s) = ?

Solution :-

First of all we will find the acceleration of car :

→ Acceleration = Final Velocity - Initial Velocity ÷ Time

→ Acceleration = 15 - 5 ÷ 7.5

→ Acceleration = 10 ÷ 7.5

→ Acceleration = 1.3 m/s²

Now, by using Second equation of motion we can find distance travelled by the car :

→ s = ut + ½ at²

→ s = 5 × 7.5 + ½ × 1.3 × (7.5)²

→ s = 37.5 + ½ × 1.3 × 56.25

→ s = 37.5 + 1.3 × 28.125

→ s = 37.5 + 29.425

→ s = 66.925 m

Therefore,the distance travelled by the car is 66.925 m.

The required answer is 66.925 m which is the distance travelled by the car.
