Answer:
The correct option is E. X(g) → X⁺(g) + e⁻
Explanation:
The electrons are attracted to the nucleus and it is necessary to provide energy to start them. Then the ionization energy is the energy necessary to pull an electron to a gaseous atom, isolated and in a fundamental state. The electrons in the last shell are the most weakly attracted to the nucleus, so these are the lost electrons.
In this way, the gaseous element is converted to a gaseous cation (positively charged ion).
Taking this definition into account, <u><em>the correct option is E. X(g) → X⁺(g) + e⁻</em></u>
Answer: 2.5m/s^2
Explanation:
Mass of car = 2250 kg
Force = 5625 N
Acceleration of the car = ?
Recall that Force is the product of mass of an object and acceleration by which it moves.
i.e Force = Mass x acceleration
5625 N = 2250 kg x acceleration
Acceleration = (5625 N / 2250 kg)
Acceleration = 2.5m/s^2
Thus, the acceleration of the car is 2.5 metres per second square.
Answer:
15,000,000 degrees Celsius
Explanation:
After the temperature reaches this degree, nuclear fusion begins to start.
Answer:
A: ≤ means less than OR equal to. < only means less than
B: 9
Explanation:
A: Because it would equal 19, and 19 is EQUAL than 19. 4(5) - 1 would equal 19, which is equal to 19, and not less than. ≤ means less than or equal to. < means less than. So its not true.
B: 47 - 2, 45. Then 5 x 9 equals 45. So 5 x 9 equals 45, then add 2 would equal 47.
Hope this helps <3
Answer: B. Mass movement always leads to landslides.
Mass movement or mass wasting is a process in which rocks, stones, debris or sediments are forced downward the hill or slope with respect to the action of gravity. Mass movement does not always leads to landslides as it depends upon the density of moving material going down the slope. The heavier and denser the material, the more profound will be the affect resulting in landslide but lighter material cannot cause landslide.
