is an atom with one valence electron more reactive than an atom with two electrone?
Answer:
An atom with a closed shell of valence electrons (corresponding to an electron configuration s2p6) tends to be chemically inert. An atom with one or two valence electrons more than a closed shell is highly reactive, because the extra valence electrons are easily removed to form a positive ion.Explanation:

A block weighing (Fg) 100 N is resting on a steel table (us = 0.68)
The minimum force to start this block moving is. N.
Answer:68
Explanation:
6.8x100
We have that for the Question "A block weighing (Fg) 100 N is resting on a steel table (us = 0.68) ." it can be said that
The minimum force to start this block moving is [tex]F_{min}=37N[/tex]
From the question we are told
A block weighing (Fg) 100 N is resting on a steel table (us = 0.68)
The minimum force to start this block moving is. N.
Generally the equation for the Maximum force is mathematically given as
[tex]F_{max} =0.74*50\\\\F_{max} =37N[/tex]
Therefore
The Minimum force = max Frictional force
Therefore
[tex]F_{min}=37N[/tex]
Hence
The minimum force to start this block moving is [tex]F_{min}=37N[/tex]

What is Force?
Aristotle famously described a force as anything that generates an object to undergo “unnatural motion. Sir Isaac Newton was one of the preferred scientists to explore gravity and force. Any kind of force is simply a push or a pull. It can be described as a push or pull on an object.
Thus, Ew=Fd=E (P=E/t)

Answer:
gravity?
Explanation:
i dont have a lot of context but this is what i thought of so...
Stars and planets form when dust and gas from space is pulled together by gravitation.
What is gravitation?In mechanics, gravity, often known as gravitation, is the force of attraction that acts on all matter. It has little impact on determining the intrinsic characteristics of common stuff because it is by far the weakest known force in nature.
In contrast, it governs the formations and evolution of stars, galaxies, and the entire cosmos by its extensive and ubiquitous action, which affects the trajectories of objects in the solar system and beyond the universe. All objects on Earth experience weight, or a gravitational pull that is proportionate to their mass and is imposed by the planet's mass.
Hence, the stars and planets form when dust and gas from space is pulled together by gravitation.

The diagram below shows a 2.0-kilogram block being moved across a frictionless horizontal surface by a 6.0-newton horizontal force.
Answer: 6.0 m/s2
Explanation:
The acceleration of the block pushed horizontally with the force of 6 N is 3 m/s².
What is force?
In order to move a body of mass 'm' kg with an acceleration of 'a' m/s², a force of magnitude → |F| = ma is needed to push the body in a specified direction.
Given is a 2 kg block being moved across a frictionless horizontal surface by a 6 Newton horizontal force.
Mass of block [m] = 2 Kg
Force on block [F] = 6 N
From the definition of force -
|F| = ma
6 = 2 x a
6 = 2a
a = 3 m/s²
Therefore, the acceleration of the block pushed horizontally with the force of 6 N is 3 m/s².

A gun kept on a straight horizontal road is used to hit a car travelling on the same road away from the gun at a uniform speed of 14.14 ms -1. The car is at a distance of 150 m from the gun when it is fired at an angle of 45° to the horizontal. What is the distance of the car from the gun when the shell hits it?
Answer:
250 m
Explanation:
In projectile, range is given as;
R = (v²sin 2θ)/g
We are given θ = 45°
Thus range of shell is;
R = (v²sin (2 × 45))/g
R = v²/g
Now, distance for the shell to hit the car will be; 150 + 14.14t
This will be equal to the range of shell;
150 + 14.14t = v²/g
Where t is time of flight
Now, time of flight is given by;
t = (2vsin θ)/g
t = (2v sin 45)/g
In surf form, we have;
t = (2v/(g√2))
Simplifying further gives;
t = (v√2)/g
Plugging this value of t into the distance equation gives;
150 + 14.14(v√2)/g = v²/g
Assuming g is 10 m/s², we have;
150 + 14.14(v√2)/10 = v²/10
Multiply through by 10 to get;
1500 + 14.14(v√2) = v²
v² - 20v - 1500 = 0
From quadratic equation calculator, we have; v = 50 m/s
Thus, t = (50√2)/g
t = (50√2)/10
t = 5√2
Plugging this into the distance equation gives;
Distance = 150 + 14.14(5√2) = 250 m

with which the ski jumper hits the slope?
Answer in units of ◦
.
Complete question is;
A ski jumper travels down a slope and leaves the ski track moving in the horizontal direction with a speed of 24 m/s. The landing incline below her falls off with a slope of θ = 59◦ . The acceleration of gravity is 9.8 m/s².
What is the magnitude of the relative angle φ with which the ski jumper hits the slope? Answer in units of ◦
Answer:
14.08°
Explanation:
The time covered will be given by the formula;
t = (2V_x•tan θ)/g
t = (2 × 24 × tan 59)/9.8
t = 8.152 s
Now, the slope of the flight path at the point of impact will be given by the formula;
tan α = V_y/V_x
We are given V_x = 24 m/s
V_y will be gotten from the formula;
v = gt
Thus;
V_y = gt
V_y = 9.8 × (8.152) = 78.89 m/s
Thus;
tan α = 78.89/24
tan α = 3.2871
α = tan^(-1) 3.2871
α = 73.08°
Thus ;
Relative angle φ = α - θ = 73.08 - 59 = 14.08°

Explanation:
A batter hits the baseball A with an initial velocity of v0 = 100 ft/sec directly toward fi elder B at an angle of 30° to the horizontal; the initial position of the ball is 3 ft above ground level. Fielder B requires 14 sec to judge where the ball should be caught and begins moving to that position with constant speed. Because of great experience, fi elder B chooses his running speed so that he arrives at the "catch position" simultaneously with the baseball. The catch position is the fi eld location at which the ball altitude is 7 ft. Determine the velocity of the ball relative to the fi elder at the instant the catch is made.
Answer:
47.4 ft/s
Explanation:
Using v² = u² - 2gs where u = initial vertical velocity of ball = 100sin30, v = final vertical velocity of ball at the time it was caught by the fielder, g = acceleration due to gravity = 32 ft/s² and s = vertical displacement = y₂ - y₁, y₁ = 3 ft and y₂ = 7 ft. s = y₂ - y₁ = 7 - 3 = 4 ft
Substituting these values into the equation, we have
v² = u² - 2gs
v² = (100sin30)² - 2 × 32ft/s² × 4 ft
v² = (100sin30 ft/s)² - 256 ft²/s²
v² = (50 ft/s)² - 256 ft²/s²
v² = 2500 ft²/s² - 256 ft²/s²
v² = 2244 ft²/s²
v = √2244 ft²/s²
v = 47.37 ft/s
v ≅ 47.4 ft/s
So, the velocity of the ball relative to the fielder at the instant the catch is made is 47.4 ft/s.
