Answer: They have different rigidities.
Explanation:
The answer would be Bismuth and Nitrogen because they have the same number of valence electrons.
Groups in the periodic table are arranged in columns. When it comes to neutral atoms, the number of valence electrons it has is equal to the main group of that element. For example, Bismuth is under group 5A of the periodic table. It has 5 valence electrons. If you look for Nitrogen in the periodic table, you will find it in Group 5A as well and this means that it also has 5 valence electrons.
It's known as the law of equal areas
Answer:
a) D_ total = 18.54 m, b) v = 6.55 m / s
Explanation:
In this exercise we must find the displacement of the player.
a) Let's start with the initial displacement, d = 8 m at a 45º angle, use trigonometry to find the components
sin 45 = y₁ / d
cos 45 = x₁ / d
y₁ = d sin 45
x₁ = d sin 45
y₁ = 8 sin 45 = 5,657 m
x₁ = 8 cos 45 = 5,657 m
The second offset is d₂ = 12m at 90 of the 50 yard
y₂ = 12 m
x₂ = 0
total displacement
y_total = y₁ + y₂
y_total = 5,657 + 12
y_total = 17,657 m
x_total = x₁ + x₂
x_total = 5,657 + 0
x_total = 5,657 m
D_total = 17.657 i^+ 5.657 j^ m
D_total = Ra (17.657 2 + 5.657 2)
D_ total = 18.54 m
b) the average speed is requested, which is the offset carried out in the time used
v = Δx /Δt
the distance traveled using the pythagorean theorem is
r = √ (d1² + d2²)
r = √ (8² + 12²)
r = 14.42 m
The time used for this shredding is
t = t1 + t2
t = 1 + 1.2
t = 2.2 s
let's calculate the average speed
v = 14.42 / 2.2
v = 6.55 m / s
Answer: 87.9 m
Explanation:
We can solve the problem by using the following SUVAT equation:
where
v = 26.1 m/s is the final velocity of the car
u = 23.06 m/s is the initial velocity of the car
a = 0.85 m/s^2 is the acceleration of the car
d is the displacement
By re-arranging the equation and substituting the numbers, we find the displacement:
